Re: [meteorite-list] Search for first U.S. lunar meteorite, Sajkowitz
Hello Rob, All, Well, I'm flattered by the mention, but I think you're selling yourself short here. It certainly took a great deal of skill/wherewithal to recognize the Lucerne Valley CK4, which I probably wouldn't have bothered to get analyzed -- even if I had, for some unlikely reason, picked it up and taken it home as a 'strange rock.' Superior Valley 014 actually looked rather chondritic from afar: http://tin.er.usgs.gov/meteor/get_original_photo.php?recno=5633196 But, to address the point - there is a goodly number of hunters here in the US who are definitely capable of finding even a weathered lunar. Give it some time. I'm sure that one will turn up on a lakebed sometime in the not-too-distant future. Oddly enough, we did find a nearly non-magnetic stone (admittedly still a chondrite) on our last trip: http://www.facebook.com/album.php?aid=201379id=508345918l=376351b876 It's pictured in the first three photos and again in the last shot, through a microscope. I'm still not really sure why I gave it a closer look, but I suppose it must have appeared somehow different from even 4-5 feet away. Magnetic canes are indispensable tools for meteorite-hunting, but when using one, it's necessary to keep an open mind. Strangely enough, the majority of the 'rare' meteorites that I can think of that have yet been found in the American Southwest have generally been magnetic; Rob's EL and CK, my acapulcoite and the other achondrite, and Ruben's...mesosiderite(?). Sonny and Nick Gessler, on the other hand, have found some interesting (and non-magnetic(!)) stones, including the Bluewing eucrite, an R-chondrite, and a CM1. And I'm sure there's more that I simply haven't heard of yet. I'd be curious to meet this Sajkowitz person. They're apparently the most successful hunter in the southwest in terms of finding new and rare meteorites (and huge, to boot!). To put things in perspective: in terms of rare meteorites, Skip Wilson has found a single ~20 gram Ureilite, out of the hundred+ meteorites that he's found. This single fellow (BIll Sajkowitz) has found more achondrites than all of the other hunters in the southwest, combined. In fact, no one else has found one over 30 grams. This guy has found two (2.1kg and 700 grams), as well as the largest single carbonaceous find by any meteorite hunter in the southwest in recent years (2.86kg). I suppose Bob Verish's martian compares in some respects, but...look at the ratio. Scores of common chondritic finds, and one or two rare meteorites. One large-ish one. It's not that Sajkowitz is more successful. He's simply a more successful hunter than Sonny Clary, Rob Matson, Skip Wilson, Ruben Garcia, etc, etc. All of us hunters in the Southwest combined. And he's either yet to find an ordinary chondrite...or he's yet to submit the hundreds he must have found. ...And no one has ever heard of him (?). Doesn't seem too likely, does it? Granted, I'm willing to accept the fact that he has *happened* to have won the lottery three times running. But if I were running the lottery, I'd be looking into things right about now. With an open mind, of course.

Re: [meteorite-list] Search for first U.S. lunar meteorite
All: Believe me - I'm looking for them along with any other achondrites without metal. That's why I do not solely depend on a metal detector or a magnet. I look at the features of the rocks: are they smooth, do they have sharp edges or rounded edges, are they different than surrounding rock, if I find something different, is there more of the same rock in the area. I have often found rocks that are odd or different to me and then keep looking and end up with a bucket full of this rock. A meteorwrong. I also check my finds with a loupe in the field - if I do find something, I want to know right away. I also believe many have been passed over. Greg S.

(1986) Cosmic Debris, Meteorites in History, Chapter 4, p. 121: Chladnite: Again, it was an observation by Charles U. Shepard that paved the way toward the identification of the pyroxenes. In 1846 he described a mineral which, he wrote, is a ter-silicate of magnesia...[and] forms more than two-thirds of the Bishopville stone. He named the mineral chladnite in honor of Chladni, the scientific founder of this department of knowledge. Two years later Shepard reported his analytical results: 70 percent silicic acid, 28 percent magnesia, and 1 percent soda, so that the ratio of oxygen in the magnesia to that in the silica was 1 to 3. In 1851 Sartorius von Waltershausen analyzed a fragment of the Bishopville meteorite and arrived at about the same results, but also found 1.5 percent alumina. Though making errors in his calculations, Sartorius did produce the correct formula - MgO,SiO2; however, he postulated that chladnite was a kind of wollastonite, in which magnesia substituted for lime. The issue was confused further in 1861, when Rammelsberg found by analysis almost 3 percent alumina, 35 percent magnesia, and only 57.5 percent silicic acid. Doubting the existence of a definite mineral, Rammelsberg did not attempt to devise a chemical formula. Meanwhile, Shepard in 1854 described the Tucson iron meteorite and speculated that certain inclusions were chladnite. J. Lawrence Smith immediately corrected him, pointing out that the inclusions were actually olivine, and added a note that he suspected chladnite is likely to prove a pyroxene. At about the same time, in 1855, Gustav A. Kenngott, professor of mineralogy at Zurich, published a memoir giving details of the minerals of what he termed the augite group of the pyroxenes. One member of the group was enstatite, which, Kenngott wrote, was a bisilicate of magnesia, was augitic in crystallization, and had the formula 3MgO,2SiO3. In 1861, when Kenngott saw Rammelsberg's analysis of chladnite, he insisted that the mineral was identical with enstatite. Smith then made two analyses of the Bishopville meteorite and reported in 1864 that chladnite consisted of 60 percent silica and nearly 40 percent magnesia. He agreed with Kenngott that the mineral was the magnesian pyroxene, enstatite, and accepted Kenngott's formula, in which the oxygen content of the magnesia to that of the silica was 1 to 2. Both Rammelsberg and Maskelyne acted to clarify the formula of enstatite, and through his work on the Breitenbach, Bustee, and Manegaon meteorites, Maskelyne recognized the existence of solid-solution series that included enstatite and bronzite. By the 1870s mineralogists began to report regularly these constituents in meteorites. __ Visit the Archives at http://www.meteoritecentral.com/mailing-list-archives.html Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list __ Visit the Archives at http://www.meteoritecentral.com/mailing-list-archives.html Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list

Dennis, I have found tiny glass spherules in some areas along the tracks - lots of them. I think it's welding slag from RR operations. I was pretty excited until someone suggested it (I never had them tested, but hard to believe folks would overlook something significant until me...). Nothing as big as you mention (other than the marbles we occasionally find). In other places I have found weathered obsidian which often has a tektite texture (though not the same). I think it's caused by solution weathering. I have a magnet cane, but I never used it to pick up a meteorite. It's just a fashion statement I guess (peer pressure). ;-) Mark B.

Re: [meteorite-list] Magnet canes are evil DONT THINK SO!
These permits are free, just a huge hassle in order to get one. They want to know everything about your visits afterward on reports that need to be sent in. Stay out of any area that requires a permit if you do not have one. We learned the hard way. Our team was snitched out by a competitive hunter from L.A. when we did not know you needed permits. A gate leading to a lake bed was left open with the permit required signs on the back of it obscured when we went through it. When we tried to exit the lake bed at the end of the day, the gate was closed and a BLM truck on the way. Needless to say, this catch em alive trap worked very well. I now research every area I enter and look carefully for signs. If I see a BLM truck, I ask questions first.

I was under the impression that it only affected the portion of Roach west of the RR tracks -- can't very well have aircraft runways crossing those tracks!

[meteorite-list] Accretion Questions: Age Material
Hi List, I think I asked something about accretion and planet formation about a year or so ago onlist, and since then I've done a bit of study on it. I still have a few questions though. In the early formation of our solar system, the protoplanetary disk that fed and formed the planets, we know that material accreted over billions of years around the Sun, but some debris was left over. If the asteroid belt is some of the leftovers from the formation of our solar system, and most meteorites come from the asteroid belt between Mars and Jupiter, then what of the Kuiper Belt? Could the Kuiper Belt material be even older than recent studies have determined Northwest Africa 2364 to be since NWA 2364 most probably came from the Asteroid belt? Are there any known meteorites that come from anywhere further than the asteroid belt? Could they? or would they be swallowed up by Jupiter before reaching the asteroid belt? This brings up another question about star systems which are very close to one another. What are the chances of material passing between them? We know the massive forces of the stars gravity holds the protoplanetary disk in place but what about the debris on the furthest outer edges of the disk? Would the orbiting/spinning of this debris cause them to be flung out into deep space away from their parent stars toward other star systems? Is this where comets come from? or the Oort Cloud which surrounds our entire solar system? And this brings me to my final question, though not really directly related to accretion it's one I've been curious about for a while now. Are asteroids dead comets? I know, lots of questions... ;) Regards, Eric (sorry if this gets posted twice) __ Visit the Archives at http://www.meteoritecentral.com/mailing-list-archives.html Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
Re: [meteorite-list] Magnet canes are evil
I took an old collapsible tripod leg and modified the bottom with a powerful magnet to use as a cane. Works well.

As he sat, he folded the cane and set it in a backpack. And it hit me - What a great design for a meteorite hunting stick. I should make a magnet cane out of a folding blind mans walking cane. So I bought one at a medical store and refined the bottom with glue and a screw to attach the magnet and made my very own meteorite hunting cane. It's great because I can fold it and put it in my back pocket or my backpack. It's also good for travel - like on a plane. It looks very much like this one. http://www.mountainside-medical.com/products/Blind-Mans-Walking-Cane-50-Inch-long.html It has always fascinated me to look at all the different meteorite hunting canes there are, and how each person puts their individuality in making them.

Re: [meteorite-list] OK, how 'bout
Hi Rob and List, Sorry to hear you are in the van of back sufferers. It must be very difficult for you. Yours is a very good suggestion...getting up close and personal is the right way to examine prospects. That's true for just about anything one is searching for. I agree with your method of using the magnet in hand and would encourage all new hunters to follow your advice. My last post was an attempt at poking fun at the more experienced hunters combined with a thinly concealed challenge as to who will discover the first American Lunite. It's inevitable that it will be foundthat's exciting.

Hi Count/List, No need for anyone to get defensive -- many people use a meteorite cane because their backs are shot. I have compressed lumbar discs, so I have lived with chronic back pain for years. Bending over a thousand times per meteorite hunting day does take its toll. (I consequently bend at the knees, not at the waist.) The point I was trying to make is that if you depend SOLELY on the feedback provided by a meteorite cane, you will unavoidably miss some meteorites -- and unfortunately, these will be the most interesting ones. I've seen my share of newcomers to the hobby that completely depend on their magnet canes as their primary detector, because they are still learning to recognize meteorites (of all types) by their visual appearance. That's all fine. But if someone is young and/or in reasonably good physical shape, I suggest they ditch the cane in favor of a handheld magnet. It forces you to place more dependence on your eyes; if you're uncertain of a particular rock, you simply pick it up for a closer look (which also has the advantage of giving you an idea of the density). You then have the option of holding the rock in one hand and the magnet in the other to test for attraction. Believe me, the sensitivity of this test is an order of magnitude greater than using the exact same magnet on the end of a cane. My intention here is not embarrassment, as you put it, but enlightenment. If I didn't want others to be successful, I'd let them merrily go about their business tapping rocks all day. --Rob -Original Message- From: countde...@earthlink.net [mailto:countde...@earthlink.net] Sent: Tuesday, August 24, 2010 1:29 PM To: Matson, Robert D.; Meteorite-list@meteoritecentral.com Subject: Re: [meteorite-list] Magnet canes are evil Robert wrote: I sometimes carry an LL6 with meThat usually cures them.

Re: [meteorite-list] Magnetism On The Angrite Planetary Body
We believe that the simplest interpretation of these data is that there was no or only a weak magnetic field on the APB at 3700 ± 700 Ma. This pretty much puts the nail in the coffin of Mercury being the parent body of Angrites. Mike Fowler Chicago Hello All, Here is an abstract by Dr. Ben Weiss of MIT, the same scientists who took a core sample from my angrite, NWA 4931 (main mass of the NWA 2999 grouping): http://www.lpi.usra.edu/meetings/lpsc2008/pdf/2143.pdf While magnetism 'sampling' from NWA 4931(NWA 2999) indicated it was most likely 'polluted' from strong earth magnets possibly by Moroccan testing at time of find, it did help Dr. Weiss's experiments which are not completed at the time of this abstract.

Re: [meteorite-list] Magnet canes are evil
Greetings, The problem with using magnet canes are, once a meteorite is touched then the weak field in the specimen (and the parent body it came from) will be altered. A magnet field may be one way of pairing specimens to certain parent bodies. Now and in the future. While it saves a lot of bending over there may come a time when a specimen's fields might be ruined in which magnetic studies may want to be done. Since there are many unique specimens found by meteorite hunters, using the canes may not be in the best interest of science and as Richard points out may allow you to miss some types of meteorites, lunites included. --AL Mitterling Mitterling Meteorites __ Visit the Archives at http://www.meteoritecentral.com/mailing-list-archives.html Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
Re: [meteorite-list] Hot AUG NV. Dry Lake bed meteorite hunt.
Hi All I just got back last week from my second NV. dry lake bed meteorite hunting trip I did on Aug 12,13,14,15. I had 5 days off from teaching flying so Off I went to my location #1 720 miles from my Airpark in Wa State . I offered to take my wife but she said it was to hot for her taste. So I packed all my tools. This time I had my trusty Kawasaki Teryx side by side 4x4 buggy with sun shade roof. I got to my site #1 after a full days drive just at dark . I was up at 5 A.M. hunting as I ate my cereal. I got a few nice ones as I ate. I started with a probe out onto this huge lake bed just to see if I could spot any out in areas I have not hunted before . I brought my X-Terra 70 so I could check the area I had found my biggest 196 gr rock last hunt when I was here. It's a sand dune so I felt there was likely a bigger one here . I set up a grid with in 10 min I had found my 1st underground rock. This gave me high hopes So I hunted on. I felt pretty small out here with my detector on this huge lake bed. After about a 1/2 hr my x-terra 70 said there was a -8. I opened up a hole there was a really nice underground meteorite about 5 inches under. It was my second biggest I have found here at this location. I hunted with my detector till I wore my self out in the heat . Then I packed it up hunted the rest of the day by foot and some on my 4x4. It was a great day of hunting So I cooked up a big N.Y steak some veggies nice salad had a cold beer. I was tired but the meteor shower was on tonight. So I laid there in the back of my truck watching the show . I woke up early it was quite chilly out . I did the same as 1st morning I ate my cereal as I hunted in my slippers. I had found 3 nice ones during breakfast. I felt it was going to be a good day so I got going as soon as I had sun. I went back hunted the dune area with my detector with no luck at all. Then I hunted a second area with my detector only a few small ones that were in cracks made my detector sing . I felt I was wasting my hunting time with my detector so I headed out to explore a new area. The day time temps were getting really hot so I did my exploring on my 4x4 buggy. I Had found a area that was producing a few nice sized rocks , So I set up a grid in my 4x4 . The sun shade on my buggy saved me as temps were hot. I did a east west grid. Going east I could see 15 ft out the left side of my buggy onto the playa . Then going west into the hot sun I could only see 5 ft out. So I did a 20ft swath across this part of the lake. I was really hitting them nice. I had my I pod on as I hunted I went threw 3 great albums Kansas, Journey, John Prine , I also did some filming. I was like a kid in a candy store I was so high on life that I was dancing like no one was watching me out on this remote lake bed. I had hunted two days now 14 hrs each day , so I was dragging my butt around . This last 3rd day I was slow at the punch. I did not hunt as I ate my cereal. I kind of just starred out onto the huge lake bed thinking of my next move. I explored areas on my 4x4 seeing if I could spot any new rocks. I worked over the north eastern edge but nothing but a arrow head. Around noon of my 3rd day I packed up my camp and drove west across NV. I was headed to my hunting location #2 and it was all the way across the state. I drove all afternoon but could not get there before dark , So I grabbed a motel, Shower Mx dinner. I had the motel give me a 4:30 wake up call the next A.M. I hit the road by 5 A.M. was standing on my location #2 dry lake bed by 6 a.m . I felt good rested up , so I watch the sun rise as I took pics ate my cereal. This was a huge lake bed but it was all hard pan so I felt good about driving my big 1 ton 4x4 out onto it. I unloaded my gear quickly headed out on the hunt. With in a 1/2 I had found my first possible space rock . After Pics of it as I found it I rolled it over for second photo on its back with GPS location I only had 1 day here so I wasted no time looking over my specimen. It looked a bit funny but put it away till I could look at it better. My next adventure was finding a moving rock. This specimen was black you could see a nice trail were this fella had moved 40 ft or more across the dry lake bed. I filmed it all for my little film iam doing. Then I stuck my Magnet up to it and WOW it stuck like it was solid medal. I recorded pics location of it but knew it was not a meteorite. I felt it was possibly magnetite. Then a bit farther I found a much larger piece about 30 lbs then 4 more smaller 5 10 lbs rocks.Then just like I knew where I was headed I drove to the east shore of the lake walked about 30 ft from my 4x4 buggy looked down there was a very nice meteorite just waiting for me to find it take home for classification . Well I was 1 happy hunter. I had found two nice looking specimens before 9:30 in the A.M. After finding my 114 grm rock I set up a grid hunt threw this area. I hunted all day

Re: [meteorite-list] Magnet canes are evil
Hi Count Deiro I read your post last night of you finding a 13.7 Kilo LL6 . Then I went to bed and had a dream of finding my own 13.7 kilo monster. Then I woke up no big meteorite. I would love to see a photo of that baby sticking out of the ground and a photo of it out of the ground. Also I gotta say I'm manifesting being that dumb ass newbie that trips over the lunar.

Ah, come on you guys. You talk like we relative newbies are a sandwich short of your picnic. I carry a very powerful (+50) neomydium on a staff I use, cause I'm a cripple and I don't like to fall down, or bend over. But, my first location device is my own pair of MK2 eyeballs backed by recognition patterns learned in studies on line, in papers, texts and handling in person thousands of meteorite wrongs and rights. Yeah, I know, I'll never catch up to you in numbers, but you'd be surprised at the difference in each individual's learning abilities, memory and powers of observation. Per esempio. I was dropped in a known strewnfield that had been worked, admittedly for six years, by one of the best hunters in the Americas and several of his equally experienced dealer/hunter friends. Within an hour I spotted a 13.7 kilo LL6 sticking three inches out of the ground. I had used my eyes first, then the cane second. If it hadn't been attracted I would have picked it up anyway to loup e it. If it was obviously not a wrong, but still ringing bells (possible planetary, or other rariety) I would have put it down. Then cubed, GPS'ed and taken a photo, put it in a baggy (if it would fit) and taken it home to the scope. But guess what?...this LL6 clicked, albeit lightly. So, you had better use a lunaite to embarass newbies with their magnets. And keep in mind that hunting for meteorites isn't a very complicated business. Hell, you can teach dogs to do it. And about that first lunar to be found in the Americas...don't be surprised if some reportably dumb ass newbie trips over it.

[meteorite-list] Accretion Questions: Age Material
I think I asked something about accretion and planet formation about a year or so ago onlist, and since then I've done a bit of study on it. I still have a few questions though. In the early formation of our solar system, the protoplanetary disk that fed and formed the planets, we know that material accreted over billions of years around the Sun, but some debris was left over. If the asteroid belt is some of the leftovers from the formation of our solar system, and most meteorites come from the asteroid belt between Mars and Jupiter, then what of the Kuiper Belt? Could the Kuiper Belt material be even older than recent studies have determined Northwest Africa 2364 to be since NWA 2364 most probably came from the Asteroid belt? Are there any known meteorites that come from anywhere further than the asteroid belt? Could they? or would they be swallowed up by Jupiter before reaching the asteroid belt? This brings up another question about star systems which are very close to one another. What are the chances of material passing between them? We know the massive forces of the stars gravity holds the protoplanetary disk in place but what about the debris on the furthest outer edges of the disk? Would the orbiting/spinning of this debris cause them to be flung out into deep space away from their parent stars toward other star systems? Is this where comets come from? or the Oort Cloud which surrounds our entire solar system? And this brings me to my final question, though not really directly related to accretion it's one I've been curious about for a while now. Are asteroids dead comets? I know, lots of questions... ;) Regards, Eric __ Visit the Archives at http://www.meteoritecentral.com/mailing-list-archives.html Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list

Re: [meteorite-list] Rocks from Space Picture of the Day - August 26, 2010 thanks to the Hupes
Hi Adam and List, Thanks for sharing your specimens, time, money, and effort with the community at large. This is another example of how science and meteoritics benefit from private involvement working in tandem with institutions and scientists. The vast majority of these NWA meteorites would be languishing undiscovered in the desert, if not for the efforts of private parties to bring them to light. Sure, it can be argued that these same meteorites could survive for thousands of years more to be discovered later by official expeditions sponsored by governments or institutions. But, the problem with that argument is that there are no official expeditions in that region. Sure the Swiss and Germans have made some expeditions into Oman, and we have ANSMET, but the official hot desert finds are tremendously outnumbered by private finds in both quantity and quality. It is a pity that more governments and institutions cannot realize this - instead of rebuking private involvement, they should embrace it and take full advantage of it. Everyone wins. When I see the Smithsonian sending teams of scientists into Mauritania, Morocco, Algeria, Niger, and the other regions of the Sahara, I might alter my stance. But I'm not going to hold my breath waiting for that to happen. Best regards and happy huntings!

My most sincere apalogies to the others who have also contributed so much! All of your efforts are greatly appreciated as you have done more for the advancement of the understanding of our earth than all of the moon missions. All at your own expense with relatively little to show for the contributions you have made. As an example. How many billions of dollars has it cost to send a probe to Vesta? And how much material from vesta or the moon could be found right here on earth if a few million dollars was spent to actively search for rocks from space here on earth? Imagine how much could be found if the succesful hunters were given government grants to hunt full time? Have a great day!

Re: [meteorite-list] Rocks from Space Picture of the Day - August26, 2010 thanks to the Hupes
This is great. Seems like a waste of the gov time and money to send expeditions when we have private entrepreneurs able to procure these rocks and donate or sell them to institutions. Its a win win for all involved. The only REAL benefit I see in having an organized expedition would be to map the strewnfields and terrestrial age determinations. But seriously, the nomads in these hot deserts are amazing meteorite hunters and get very little credit for the incredible finds they produce.

How many billions of dollars has it cost to send a probe to Vesta? $0.45 Billion and this includes a second asteroid, Ceres. You could say the Vesta mission is less than half that since the extended mission would be at Ceres. While sounding high, this is typical of this type of mission. If distributed between among all US taxpayers, this works out to 1/3 of a cup of mud from Charbucks or several good cups of coffee. And how much material from vesta or the moon could be found right here on earth if a few million dollars was spent to actively search for rocks from space here on earth? None. Lunars are known to be lunars only because we went ot the moon and brought back samples. Martians are only known to be Martians because we've sent spacecraft to that planet and smelled the air tasted the soil. HEDs are suspected of coming from Vesta, but until Dawn arrives there and examines and measures that body in situ, HEDs coming from Vesta is still not a proven fact. Imagine how much could be found if the succesful hunters were given government grants to hunt full time? Have a great day! Steve That happens every year, in Antarctica. To be honest, successful hunters are doing a great job finding material now, and often get much greater rewards by hunting in the name of capitalism. Remember, if they find them now, the rocks and the profits are theirs to keep. If they are funded by a government, they get their salaries and the government keeps all the rocks. Free enterprise is a much better route to finding meteorites, for everyone.

[meteorite-list] Rocks from Space Picture of the Day - August 26, 2010 thanks to the Hupes
Wow those were some great images of those great meteorites. Be nice to see those in person and see the texture and detail and beable to hold them with glooves of course :) I read that if the Smithsonian got involved with NWA hunts that might be a good thing. I wonder how that would change meteorite hunting and the fact of the matter, if the USA was off limits to everyone except for government funded meteorite expeditions? I have always wondered how much money is spent on the Antarctica expeditions for locating and recovery of meteorites down there? I bet its a pretty penny. If that would happen in the US and NWA I could see science and funding would suffer more and it would turn into what is happening in Australia, where funding isn't available for research and recovery in the meteoritic science sector. I think its great what the Smithsonian is doing in Antarctica, but if they applied that to other parts of the world, I could see the hopes of finding a Lunar meteorite in the USA as a dream and not a reality. To privatize meteorite hunting and collecting could also cause problems for the mere fact that what ever is recovered would be the property of the government and we would be at square one, no meteorites, they would be sealed and stored away in vaults. The involvement meteorite hunters, collectors, and newbies keeps this world happening and moving forward. I am excited to see whats going to be happening in the future with meteorite collecting and the recovery processes that the community might face, till then lets pray for a new meteorite fall... and soon :) Shawn Alan IMCA 1633 eBaystore http://shop.ebay.com/photophlow/m.html?_nkw=_armrs=1_from=_ipg=_trksid=p4340 [meteorite-list] Rocks from Space Picture of the Day - August 26, 2010 thanks to the Hupes Galactic Stone Ironworks meteoritemike at gmail.com Thu Aug 26 12:12:25 EDT 2010 Previous message: [meteorite-list] Rocks from Space Picture of the Day - August 26, 2010 thanks to the Hupes Next message: [meteorite-list] Rocks from Space Picture of the Day - August26, 2010 thanks to the Hupes Messages sorted by: [ date ] [ thread ] [ subject ] [ author ] Hi Adam and List, Thanks for sharing your specimens, time, money, and effort with the community at large. This is another example of how science and meteoritics benefit from private involvement working in tandem with institutions and scientists. The vast majority of these NWA meteorites would be languishing undiscovered in the desert, if not for the efforts of private parties to bring them to light. Sure, it can be argued that these same meteorites could survive for thousands of years more to be discovered later by official expeditions sponsored by governments or institutions. But, the problem with that argument is that there are no official expeditions in that region. Sure the Swiss and Germans have made some expeditions into Oman, and we have ANSMET, but the official hot desert finds are tremendously outnumbered by private finds in both quantity and quality. It is a pity that more governments and institutions cannot realize this - instead of rebuking private involvement, they should embrace it and take full advantage of it. Everyone wins. When I see the Smithsonian sending teams of scientists into Mauritania, Morocco, Algeria, Niger, and the other regions of the Sahara, I might alter my stance. But I'm not going to hold my breath waiting for that to happen. Best regards and happy huntings!

[meteorite-list] New View of Gas and Dust in the Solar Nebula (Genesis)
http://www.psrd.hawaii.edu/Aug10/gas-dust-Oisotopes.html New View of Gas and Dust in the Solar Nebula Planetary Science Research Discoveries August 25, 2010 --- The current view holds that gas and dust in the solar nebula began with the same oxygen isotopic composition, then changed by processes in the nebula. A new view suggests that dust and gas had vastly different mixtures of oxygen isotopes in the first place. Written by G. Jeffrey Taylor Hawai'i Institute of Geophysics and Planetology The recognizable components in meteorites differ in their relative abundances of the three oxygen isotopes (^16 O, ^17 O, and ^18 O). In particular, the amount of ^16 O varies from being like that of the Earth to substantially enriched compared to the other two isotopes. The current explanation for this interesting range in isotopic composition is that dust and gas in the solar nebula (the cloud of gas and dust surrounding the primitive Sun) began with the same ^16 O-rich composition, but the solids evolved towards the terrestrial value. A new analysis of the problem by Alexander Krot (University of Hawai'i) and colleagues at the University of Hawai'i, the University of Chicago, Clemson University, and Lawrence Livermore National Laboratory leads to the bold assertion that primordial dust and gas differed in isotopic composition. The gas was rich in ^16 O as previously thought (possibly slightly richer in ^16 O than the measurements of the solar wind returned by the Genesis Mission, but that the dust had a composition close to the ^16 O-depleted terrestrial average. In this new view, the dust had a different history than did the gas before being incorporated into the Solar System. Solids with compositions near the terrestrial line may have formed in regions of the solar nebula where dust had concentrated compared to the mean solar dust/gas ratio (1 : ~100). The idea has great implications for understanding the oxygen-isotope composition of the inner Solar System and the origin of materials in the molecular cloud from which the Solar System formed. Reference: * Krot, A. N., Nagashima, K., Ciesla, F. J., Meyer, B. S., Hutcheon, I. D., Davis, A. M., Huss, G. R., and Scott, E. R. D.

Two Reservoirs of Oxygen Isotopes The oxygen we breathe is composed of three isotopes with atomic weights of 16, 17, and 18. ^16 O is the most abundant (99.76% of all the oxygen), followed by ^18 O, with ^17 O bringing up the rear (only about 4 ten-thousandths the abundance of ^16 O). In spite of ^16 O being so abundant compared to the others, the set of three isotopes provides exceedingly important information about how the Solar System formed and about geochemical processing on the planets. One informative way to plot oxygen isotopic data is to use all three isotopes by plotting the ^17 O/^16 O ratio against the ^18 O/^16 O ratio, as shown in the diagram below. In general, rocks in and on a given planet fall along a well-defined line with a slope of about ½; the line for terrestrial rocks is labeled TF in the graphs below. A striking discovery made more than three decades ago by Robert Clayton (University of Chicago) and coworkers was that primitive materials in chondrites plot along a line that suggests addition or subtraction of ^16 O. [Plot of oxygen isotope ratios in chondrules and CAIs in meteorites.] Plot showing the ^18 O/^16 O and ^17 O/^16 O ratios in chondrules and CAIs in meteorites in parts per thousand. Data have been standardized to standard mean ocean water (SMOW) and plotted as deviations from that value. The meteorite particles define a line with much steeper slope than the fractionation line (TF) line, which is consistent with loss or addition of ^16 O. A shorthand way to show the deviation from the TF line is to plot the vertical displacement of any point from it, as indicated graphically in purple. This parameter (Î^17 O) is called big delta O-17 by cosmochemists. We use it in subsequent diagrams. The explanation for the difference between primitive materials and the terrestrial line is that the dust and gas that made up the primitive Solar System were both rich in ^16 O, but that some process produced substantial amounts of dust depleted in it. Several imaginative ideas were invented by cosmochemists to explain the existence of two isotopically distinct reservoirs. One class of models depicts formation of the ^16 O-poor reservoir (the one near the terrestrial fractionation line in the diagrams) by a chemical effect produced by irradiation of carbon monoxide (CO) by ultraviolet light.

University Blvd., Room 308 From Hawthorne House to the Papal Palace: Adventures of a Vatican Planetary Scientist Brother Guy Consolmagno, SJ (LPL Ph.D. 1978) has worked as a planetary astronomer on every continent, from teaching at the University of Nairobi to collecting meteorites in Antarctica. For this lecture, he'll share some of his adventures along the way, including how he helped write the first graduate student plays (and set up the grad student residence Hawthorne House), information about his space club at the Starehe Boys' Centre in Kenya, and tales of his intimate dealings with aliens (well, alien rocks, at least) in the bowels of the Vatican. Dr. Consolmagno is curator of the Vatican meteorite collection in Castel Gandolfo. His research explores the connections between meteorites and asteroids, and the origin and evolution of small bodies in the solar system. After obtaining his Ph.D. in Planetary Sciences from the University of Arizona in 1978, Brother Consolmagno worked as a postdoctoral fellow and lecturer at the Harvard College Observatory, and from 1980-1983 continued as postdoc and lecturer at MIT. In 1983 he left MIT to join the US Peace Corps, where he served for two years in Kenya teaching physics and astronomy. Upon his return to the US in 1985 he became an assistant professor of physics at Lafayette College, in Easton, Pennsylvania, where he taught until his entry into the Jesuit order in 1989. He took vows as a Jesuit brother in 1991, and studied philosophy and theology at Loyola University, Chicago, and physics at the University of Chicago, before his assignment to the Vatican Observatory in 1993. Dr. Consolmagno studies the nature and evolution of small bodies in the solar system. His work in the 1970s on the moons of the outer solar system predicted many of the features later discovered by the Voyager and Galileo spacecraft, including the first published suggestion of Europan sub-crustal oceans with the possibility of life. Models for the geochemical evolution of lunar basalts and basaltic meteorites eventually led to the identification, on geochemical grounds, of asteroid Vesta as the parent body of the eucrite, diogenite, and howardite meteorites. His doctoral thesis on the role of electromagnetic forces in chemical fractionations of the early solar system pioneered the field of gravito-electrodynamics, the behavior of dust subjected to both gravitational and electromagnetic forces, and he was the first person to apply this concept to describe the dynamics of Jupiter's dust ring. Dr. Consolmagno's present research is centered on understanding the origin of moons, meteorites, asteroids, dwarf planets, and trans-Neptunian objects. One continuing project is measuring the density, porosity, and magnetic properties of meteorites, with applications to understanding the lithification of meteorites and the structure of their asteroidal parent bodies. He is also involved in telescope observations measuring the spectra of small bodies in the outer solar system. Brother Consolmagno has authored/coauthored several books, including: Turn Left at Orion (with Dan M. Davis; Cambridge University Press, 1989); Worlds Apart (with Martha W. Schaefer; Prentice Hall, 1993); The Way to the Dwelling of Light (U of Notre Dame Press, 1998); Brother Astronomer (McGraw Hill, 2000); God's Mechanics (Jossey-Bass, 2007), and The Heavens Proclaim: Astronomy and the Vatican (VO Publications, 2009).

Re: [meteorite-list] Holbrook Tektites ( Magnet canes are evil)
Dennis, Mark,List, Interesting you mention finding rocks that resemble certain tektites. You describe them as looking translucent and weathered with a tektite texture. Years ago I found what I thought was a strewnfield of tektites in Southern AZ. They too looked like what you found. I took them to ASU and Dr. Moore had his assistant attempt to melt one of them. He explained that a true tektite would simply melt like glass similar to the way a glass blower melts glass. If however it gets frothy and white it is not a tektite but likely natural obsidian glass. This had something to do with the amount of water. Apparently tektites are much dryer than obsidian. Well, they tested frothy and therefore deemed to be sand blasted obsidian. I believe he also said they are not magnetic. Some of mine were magnetic others were not. Curiously, I have since found that Surf-tumbled Sea glass has exactly the same appearance as these sand blasted obsidian orbs I found in the desert. The only difference is that sea glass does melt like tektites so, the melting test does not work on them. In fact other than the flanged buttons, to me many of the Tektites look more like Sea-glass than anything else. If you are unaware of it. Sea glass is largely a product of surf tumbled glass that has been littered or discarded by human activity in the past. If you Google it there are lots of people selling it. What I found looks like either Columbianite or Georgia Tektite. two different looking types all in the same find area. Really Makes me wonder about the true origin of Tektites.

[meteorite-list] New International Study Shows Some Asteroids Live in Own 'Little Worlds'
http://www.colorado.edu/news/r/11335e94d14fe23de65b3cbbabd145dc.html New International Study Shows Some Asteroids Live in Own 'Little Worlds' University of Colorado at Boulder August 25, 2010 While the common perception of asteroids is that they are giant rocks lumbering about in orbit, a new study shows they actually are constantly changing little worlds that can give birth to smaller asteroids that split off to start their own lives as they circle around the sun. Astronomers have known that small asteroids get spun up to fast rotation rates by sunlight falling on them, much like propellers in the wind. The new results show when asteroids spin fast enough, they can undergo rotational fission, splitting into two pieces which then begin orbiting each other. Such binary asteroids are fairly common in the solar system. The new study, led by Petr Pravec of the Astronomical Institute in the Czech Republic and involving the University of Colorado at Boulder and 15 other institutions around the world, shows that many of these binary asteroids do not remain bound to each other but escape, forming two asteroids in orbit around the sun when there previously was just one. The study appears in the Aug. 26 issue of Nature. The researchers studied 35 so-called asteroid pairs, separate asteroids in orbit around the sun that have come close to each other at some point in the past million years -- usually within a few miles, or kilometers -- at very low relative speeds. They measured the relative brightness of each asteroid pair, which correlates to its size, and determined the spin rates of the asteroid pairs using a technique known as photometry. It was clear to us then that just computing orbits of the paired asteroids was not sufficient to understand their origin, said Pravec. We had to study the properties of the bodies. We used photometric techniques that allowed us to determine their rotation rates and study their relative sizes. The research team showed that all of the asteroid pairs in the study had a specific relationship between the larger and smaller members, with the smallest one always less than 60 percent of the size of its companion asteroid. The measurement fits precisely with a theory developed in 2007 by study co-author and CU-Boulder aerospace engineering sciences Professor Daniel Scheeres. Scheeres' theory predicts that if a binary asteroid forms by rotational fission, the two can only escape from each other if the smaller one is less than 60 percent of the size of the larger asteroid. When one of the asteroids in the pair is small enough, it can make a break for it and escape the orbital dance, essentially moving away to start its own asteroid family, he said. During rotational fission, the asteroids separate gently from each other at relatively low velocities. This is perhaps the clearest observational evidence that asteroids aren't just large rocks in orbit about the sun that keep the same shape over time, said Scheeres. Instead, they are little worlds that may be constantly changing as they grow older, sometimes giving birth to smaller asteroids that then start their own life in orbit around the sun. While asteroid pairs were first discovered in 2008 by paper co-author David Vokrouhlicky of Charles University in Prague, their formation process remained a mystery prior to the new Nature study. When the binary asteroid forms, the orbit of the two asteroids around each other is initially chaotic, Scheeres said. The smaller guy steals rotational energy from the bigger guy, causing the bigger guy to rotate more slowly and the size of the orbit of the two bodies to expand. If the second asteroid is small enough, there is enough excess energy for the pair to escape from each other and go into their own orbits around the sun. Several telescopes around the world were used for the study, with the most thorough observations made with the 1-meter telescope at Wise Observatory in the Negev Desert in Israel and the Danish 1.54-meter telescope at La Silla, Chile. This study makes the clear connection between asteroids spinning up and breaking into pieces, showing that asteroids are not static, monolithic bodies, said Vokrouhlicky. The asteroids that populate the solar system are primarily concentrated in the main asteroid belt between Mars and Jupiter some 200 million miles from the sun, but extend all the way down into the inner solar system, which are known as the near-Earth asteroids. There are likely about a million asteroids larger than 0.6 miles, or 1 kilometer, in diameter orbiting the sun. Last month, NASA's WISE spacecraft spotted 25,000 never-before-seen asteroids in just six months. Astronomers believe most asteroids are not solid chunks of rock, but rather piles of debris that come in shapes ranging from snowmen and dog bones to potatoes and bananas, with each asteroid essentially glued together by gravitational forces.

The Yarrabubba Impact Structure Impact Minerals' 20%-owned Yarrabubba Project, located 50 km south east of Meekatharra in Western Australia, has most of the geological characteristics of the World Class Sudbury mining camp in Canada which has produced about 20% of the World's nickel. It is generally accepted that a major meteorite impact occurred at Sudbury and that this gave rise to the many large nickel-copper-PGE deposits in that area. The Yarrabubba Joint Venture tenements cover about 1,200 sq km. Within these there is a very large magnetic low in regional airborne magnetic data and outcrops of distinctive geological structures indicative of shock metamorphism which have been interpreted (in published scientific papers) to be caused by a major meteorite impact. The feature in this area is called the Yarrabubba Impact Structure. Interpretation of close-spaced airborne magnetic data flown by the Yarrabubba Joint Venture has defined in more detail the large magnetic low (Figure 1). It is at least 50 km long and up to 15 km wide and is interpreted to be caused by both the meteorite impact and by related subsequent hydrothermal fluids that may form mineral deposits within the intensely fractured rocks. These fluids have caused extensive magnetite destruction and development of sericite, an alteration mineral. The airborne magnetic data has also revealed multiple radial and concentric structures prospective for deposits of nickel, copper and platinum group metals, similar to those which host nickel deposits at the Sudbury mining camp. Soil Geochemistry Results Previous soil geochemistry programmes at Yarrabubba identified Target NH1 as a highly ranked area of about 10 sq km that warranted infill soil sampling to define specific drill targets (Figure 1). A programme of 1,494 soil samples taken at a spacing of 50 m by 50 m was completed in the June Quarter 2010. The samples were submitted for multi-metal analysis by the MMI-M partial digest method at SGS Laboratories in Perth Two areas, called NH1A and NH1B, contain significant nickel responses of between 10 and 58 times background and which are each coincident with a north west to south east trending zone of linear magnetic anomalies interpreted to be part of a major concentric fault related to the impact event. The two areas are coincident with strong magnetic gradients (Figure 2). At Target NH1A the peak nickel responses are in part coincident with strong cobalt responses of between 20 and 55 times background and weak copper responses of between 5 and 6 times background. At Target NH1B the peak nickel responses are sub-parallel to and are partly coincident with modest copper responses of between 6 and 10 times background. The south east part of NH1B is also coincident with modest to strong cobalt responses of between 10 and 50 times background. Drill Programme Applications for Aboriginal heritage surveys and Government environmental approvals were lodged in the June Quarter. The Heritage Survey is expected to be completed by the end of September and Government approvals are due shortly. A drill programme will commence as soon as possible after the statutory approvals have been received. There are many other smaller areas containing elevated nickel responses that may warrant further exploration if the drilling at NH1A and NH1B is encouraging. __ Visit the Archives at http://www.meteoritecentral.com/mailing-list-archives.html Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
[meteorite-list] New Classifications from the Met Bulletin - Irons and more
Hi List, Bob King's earlier post about Mifflin finally being published in the Met Bulletin inspired me to go have a look at the recent updates. Several interesting meteorites have been approved in the last 3 days, including several new irons : One Brazilian iron is massive and weighs 2 metric tons - Campinorte. One iron (NWA 959) has yellowish inclusions and dates back from 2001! It took nine years to go from provisional status to official! Greg Hupe is listed as the main mass owner. Hey Greg - got any photos of this one to share? And what is your opinion of the yellow inclusions? Another Hupe iron is NWA 968 that also languished in provisional status for nearly 10 years. A rare iron IIIE type from Brazil that weighs 200 kilos - Porto Alegre. Another meteorite that is not an iron is New Deal from Texas, an H6 chondrite. I just like the name of this one. The rest of the newly approved meteorites can be seen at this link - http://tin.er.usgs.gov/meteor/metbull.php?sea=sfor=namesants=falls=valids=stype=containslrec=50map=gebrowse=country=Allsrt=namecateg=Allmblist=Allrect=phot=snew=7pnt=Normal%20tabledr=page=0 Best regards, MikeG PS - Hey Greg and Adam, what else have you guys been quietly sitting on? ;) -- Mike Gilmer - Galactic Stone Ironworks Meteorites http://www.galactic-stone.com http://www.facebook.com/galacticstone __ Visit the Archives at http://www.meteoritecentral.com/mailing-list-archives.html Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list

I really love ebay's definition of used that they manage to insert into all auctions for used items... Used: An item that has been used previously. I'm sure glad they pointed that out for everyone!

Yeah! And the New Deal is mine! It is a small meteorite, only 230g, and a few slices have already been reserved, so if anyone is interested, you have better speak up very quickly. Really! Anne M.

Looks like the khareef in the southern Arabian Peninsula. Flash floods are a real killer, I was in one in '98 that killed 5 people and don't ever want to in one again. Hunt the Lunar!
