Re: [meteorite-list] Snow and Mars water and meteorites
Pictures I've seen from the rover that was on Mars makes it look like the typical rocks are weathered to a rusty brown color...like many olivine/pyroxene (w/iron) rich rocks here on earth.

If this is true, since snow (sublimated frost) can form anywhere on Mars, there ought to be more gullies in the lower elevations (say, the rim of the Hellas Basin) than in the higher elevations (Tharsis plateau), at similar distances from the equator. This is because the pressure on Mars is near the Triple Point pressure, and a similar amount of snow in either place ought to produce more gullies in the place where the air pressure helps most. There are some assumptions here, and certainly the gulley system shows a wide range of ages. One must not be too hasty in jumping to conclusions, but a superficial glance does show more larger gullies at lower elevations. A precise count and control for age from crater counts may be helpful. Further, there should be some variation in the alteration of same-age Martian meteorites originating from high elevation on Mars to low elevations. As the Morroccans busily increase the sample (and non-Morrocans like Mr Verish :), we will see. Francis Graham __ Do you Yahoo!? Yahoo!

Bill, Thank you for this informative response. I have a nice chunk of Zag that has one surface that looked like a slickenslide...but I've had doubts because it looked smooth/polished, and I was thinking these subtle striations should be grooves with edges. Not the case by your answer. If I can get a good picture of it this weekend, I'll send it to Jeff in Australia and see if he'll put on his site. Thanks again for clarification for all of us.

Michel, Perhaps I can give you an insight into just what slickensides are all about. A slickenside is a fault surface or fault-plane which exhibits movement and dislocation,frequently warped,broken,and frequently offset. When you see a true slickensides it is polished because the sliding surfaces are under great pressure as they move slowly, opposing surfaces are polished and often striated grooved. If you are thinking of impact structure you will most likely find evidence of directional striations as in a dynamite exposition but you will not see the polishing as evidenced in slickenside.

[meteorite-list] follow-up finds and their documentation
Hello all, I'm about to ask one of those wandering (also wondering) questions again...one that probably won't be answered to everyone's satisfaction, especially mine. Here goes... With all the latest Campos, Sikhote Alins, Kainez, Gao, Gold Basin, and others (I'm sure) being found these days...what (if any) verification and documentation is done with theselatest finds of known meteorites. Are finders required/supposedto follow any particular stepsto comply with the rules(whatever they are)of the Society that should eventually affect the total weights for these known falls/finds. Is the documentationof these and other "follow-up" findsout of control these days with the interest of meteorites being so high, and the desire to find more specimens paralleling that interest?I'm just curious. It doesn't bother me one way or the other...I just find the issue very daunting from a documentation point of view. I suppose a newly foundSikhote Alin looks like the ones found years before...and that most buyers look at it and say that is a SA andwould buy it. Is it documentedand added it to a running total? Is it supposed to be?Campos are also somewhat distinct in their appearance, but I'm not sure I could tell if one is for sure...if someone asked. The stones are often distinct in their appearance for a given name meteorite, and most buyers know what they are looking at...but (for example)some Gold Basin look just like many NWA's found in recent years.Weathered...and old looking. The source of supplieris always the key for us buyers...we have to have trust. The IMCA helps this situation in my opinion.Another key is tovisually recognize the look of a particular meteorite from experience. A problem with this is that the experience level for recognizing a given meteorite can have a wide range within a group of buyers. Notice I did not lump NWA's into this because it becomes even more gray as you look at them...from my simple mind's perspective. However, the scrutiny is much higher for them than the others...even though the level of "documentation" maybe the same...none, other than it looks like the others and were found in the vicinty of the original finds.

Re: [meteorite-list] when will the US see another meteorite fall and recovery?
Eric and others, The fireball in PA was a big one. I missed seeing it by seconds...I was out front working and stepped in for a minute for a drink of water...only to miss it. As for where it landed...possibly in the bordering counties of PA and NY, near the middle of PA. There is some farmland in that area...but most of it is heavily wooded eastern mountains (or foothills to you Western guys). Tough terrain to find a couple rocks...especially when most of these two states are one big rock, thinly covered by a little bit of topsoil and vegetation...the woods and underbrush are almost jungle like in many of these areas. A tough area to find meteorites...as far as I know from reports, no one saw it come in close anywhere...so they are probably sitting on the side of a mountain covered by six inches of leaves, etc. and two feet of snow (right now). The mountains and terrain of Colorado also offers great challenges to finding these falls. Flatlands and deserts are obviously the optimum locations for falls.

Re: [meteorite-list] when will the US see another meteorite fall and recovery?
Mike and others, Since it has been snowing all day and is expected to do the same all day tomorrow (total of 30 inches or so)...I think I'll have time to read more of Nininger's book. The one thing that stands out from his book accounts of searching and finding meteorites (usually indirectly through others) is that he worked really hard at it. If it were a fireball he was chasing...he would drive hundreds of miles around (at least three sides) of a suspected fall, interviewing people to (mathematically) determine the fall area within several miles in each direction. Then he would focus on that area, educating people by showing them real meteorites he had in his pocket, and telling them to contact him if they found anything. He would go to schools, assemblies of all types, etc. to spread the word of the local fall...and of course the promise of money if they found some. Often he would have to wait several months to a year or more to hear from people from that area. And like today's experiences, he often came up empty from his efforts. He had great perseverance. Some interesting things he said that should be remembered...1) meteorites usually stop burning and go out about eight miles or so up because the velocity is much lower than when it first hit the atmosphere, reducing friction.. 2) If you see a fireball go into the horizon...it is not just over there, it is probably a couple hundred miles away (why? refer back to item 1) 3) Where one or a few specimens are found from a significant new fireball, there are probably many specimens still out there to be found. 4) And last but not least, go back to where older falls/finds have occurred and try searching for, and asking about more meteorite finds. Well I'll stop yapping and say goodnight, Happy Hunting, John PS It still blows my mind that Bensour fell in the middle of the largest ongoing meteorite search field (NWA) in the world.

I don't know if anyone remembers this post and a few other earlier ones which referred to a possible fall which may have occurred more or less in my own back yard.

I only looked in the area of a golf course near Amherst, that according to at least one eyewitness would have been in the area of it's flight path. Needless to say, I came home empty handed.

Hello all, As David Hardy suggested...things sure are slow on list. I'll try to add something. I'm reading Nininger's book, Find A Falling Star. I'm only a third of the way through...and I'm hooked! I keep looking out back to see if a fireball might be passing by... or maybe I'll find a nice size crater in the backyard when I take the dog out in the morning. Al Mitterling told me this book would stir my desires to go out and find a rock from space. Everyone interested in meteorites should read it. What a story Nininger had to tell. Let's hope Steve Schoner gets well enough to share his observations of the man he met with years ago. In the book he seems to be running from one fall or find to another for about 20 years (so far, from my reading)...mostly in the US, Canada or Mexico. Falls seemed to happenmore frequently during those days, especially in the Midwest. My question is...are we in a meteorite drought (falls)here in the US and elsewhere, or is their no one out there doing what Nininger did when a fireball is witnessed? Obviously it takes lots of people interested in finding them to eventually bring them to someone like a Nininger...who advertised in papers, spoke to groups and individuals, offering money, etc. I knowwe've had sightings...but I think the last recorded meteorite falls in the US were Portales Valley and Monahans in 1998. Can anyone come up with a later one? I think we are in a drought. Let's hope this is the year we see another or two...and of course, it happens in the backyard of someone on the list. When John

Matt, Tom, Dirk, Michael and others, From Dirk's and Matt's reports, they are still out there falling. Maybe as Nininger promoted, the finds are out there to be had too.Possibly the latest energies by David Freeman and others to help educate the public will be the starting point fora new batch of finds. If the IMCA group (including me) can help "turn up the volume", maybe we all will benefit with some more materials.

Hello Al and others, I have been at collecting for about 4 years after finding some of the most convincing meteorwrongs you'll ever see. Someday I'll get them up on web for you all to see. It turned out to be a rocky-like slag that had a lot of flux in it from oldtime smelting. Melted surfaces with cupped features, ball-like surface features that looked like chondrules, etc...might fool many early collectors. Amigo Bob (Haag) finally gave me the bad news. I actually studied, watched auctions, etc. for about a year before I started buying. I wonder how many other folks start out by finding a meteorwrong? Quite a few I would bet. As for Arizona...I visited once in 1962...but my parents drove right by the crater. Too bad.

My first collection piece was from Meteor(ite) Crater in the 1960's. Probably 1965 or 1966. Went to the crater as a kid. They sold Canyon Diablo Meteorite oxide (shale) on a card. I still have the cards which are purple, reddish in color and say From Outer Space showing a meteor in flight with the oxide glued in the center of the fireball. It has information about the impact on the back. I can't say that I really got serious about collecting until the 1980's though. I did make an effort to obtain a iron meteorite from Meteor(ite) Crater in 1979 but they didn't like the idea of selling iron meteorites to just anyone, so I settled for a larger chunk of iron oxide which I still have in my collection. After that I got serious. Thank-you Robert Haag! Also Thank-you Blaine Reed! John Sinclair wrote about the attractions around Tucson. I agree with him on all of his well suggested places. One such place he mentioned was Tombstone and the shoot out at the O.K. Corral.

Re: [meteorite-list] More on NWA 753 and NWA 978
Bernd, Mark and Dean, Thank you for your responses on NWA R-chondrites. My comparison is that my two slices of 978 looks a lot fresher than my two 753 slices and one individual, which are more oxidized (orange colored) than the 978 I have. The chondrules appear to be rounder and smaller too in the 978. The 782 and 800 ones are also relatively fresh looking, but to me they look different from 753 and 978. The 978 and Dean's latest material look alike by my comparisons, and yes Bernd they have light colored chondrules in a greyish black matrix that is like looking into the milky way. Very nice material. The new piece from Dean had a fair amount of white caliche on the exterior, but the interior is fresh looking. The price of these R meteorites ($7 to 20/g), along with Allende($4 to 5/g), Bilanga ($12 to 18/g), Gao ($1 +/-), Zag ($0.50 to $2/g), SA ($0.30 to $1.00/g) offer some of the best deals out there right now for great falls and finds.

Re: [meteorite-list] marjalahti pallasite..... yada yada yada
Elton, Rosie, Steve and others, This is a tiresome subject. Rosie you were right on target last week when discussing the attitude of Steve who seems to often be offering his mine is better than yours attitude, and again today when you commented on Elton's attempt to lead Steve to better deals. I would have to say the number of willing traders out there is shrinking by the day. The approach taken by Steve is brash and irritating. The rumors of some of these dealings are not surprising. I'm sure a book could be written about them all but who would want to read it. I think he even dreams of such a book. No fame will come from the approach taken. Steve, you should treasure your collection a little more. The revolving door approach demonstrates that these things are nothing more than badges to you...and we have the problem of having to experience your presentations with each new wonder...it is not appealing to me or most others I would suspect. I understand the idea that these are like cash, and trading is one of our options as collectors. But you seem to have developed a new method. Steve, I think you might be surprised at how many awesome, intact (for the most part) meteorite collections that are out here. Many awesome specimens that were acquired at a great price or through a great deal. Here is to the true collectors. Here is to field collecting of any kind...that is where your mind begins to treasure what discovery and collection is all about. Everyone should do both if they can. I would not trade many of my personal earthy finds...even for a slice of marjalahti. Well, to all those going to Tucson...have a safe and enjoyable trip, and hopefully get along with each other. I would love to be there to meet all of you, including Steve. But I'll remain back east dreaming of Gold Basin and the rest of the show. Report in please.

In other words, in this particular case the source may not necessarily Vesta, but a Vesta-like asteroid. If there are classes of asteroids, and my guessis that it will turn out that there are, then you get into the differentiation problem and the problem of parent body size. Wild stuff, but that's how I think this is going to play out.

As always, thank you for responding to my question and comments. You guys are going to force me back into the books to see what I read, but obviously didn't learn. As I remember it, the evidence with Vesta has to do with the large gouge in it's side that shows different levels of crust (eucrite) and sub crust (diogenite). This leads to another challenge or question, if we think all or most of HED's come from Vesta, then why do they look so different from each other?. Some eucrites are white or grey, while others are a shade of light brown/yellow. The differences in diogenites are even greater. Is the new olivine diogentite thought to be from Vesta also? My answer would be they sure could be. My experience in finding plutonic rocks here on earth is that the same area of exposure searched can have a wide variety (in appearance) of same type type rock. Some are more rich in one mineral than another...but for the most part still made up of the same ingredients. Temperature and pressure of the magma at one location versus another precipitates out minerals at different rates. Also the makeup of the magma then changes as it losses more of one element than others, changing the resulting rock formation mineral ratios.

The topic that Bernd had started was on asteroid color clans and that at least 90 percent of asteroids are associated with families (from collisions in the past). No doubt the Vesta HED's are from chunks broken off from Vesta in an impact and that have made their way into an orbit that upon further impact has allowed meteoroids to end up in some of the kirkwood gaps where they can be purbatrated into Earth crossing orbits.

Re: [meteorite-list] Asteroid Color Clans
Hi Al, Great stuff Al. As always, thank you for responding to my question and comments. You guys are going to force me back into the books to see what I read, but obviously didn't learn. As I remember it, the evidence with Vesta has to do with the large gouge in it's side that shows different levels of crust (eucrite) and sub crust (diogenite). This leads to another challenge or question, if we think all or most of HED's come from Vesta, then why do they look so different from each other?. Some eucrites are white or grey, while others are a shade of light brown/yellow. The differences in diogenites are even greater. Is the new olivine diogentite thought to be from Vesta also? My answer would be they sure could be. My experience in finding plutonic rocks here on earth is that the same area of exposure searched can have a wide variety (in appearance) of same type type rock. Some are more rich in one mineral than another...but for the most part still made up of the same ingredients. Temperature and pressure of the magma at one location versus another precipitates out minerals at different rates. Also the makeup of the magma then changes as it losses more of one element than others, changing the resulting rock formation mineral ratios. I think I answered my own question, but I'M WAY OVER MY HEAD HERE!!!

The topic that Bernd had started was on asteroid color clans and that at least 90 percent of asteroids are associated with families (from collisions in the past). No doubt the Vesta HED's are from chunks broken off from Vesta in an impact and that have made their way into an orbit that upon further impact has allowed meteoroids to end up in some of the kirkwood gaps where they can be purbatrated into Earth crossing orbits. Yes they are from other sources but they originated from the same source or asteroid.

I don't think there is much doubt about the Mars type meteorites (SNC's) are from Mars and the Lunar meteorites are from the moon as we have been there and have material to compare to. With the color clans coming into play we can at least say that certain meteorites are from certain families now. On a related note Mar's moon Phobos is very similar to the CV3's like Allende but there are also many other asteroids out there with that spectral match (could it be the same clan?) I have always thought with the larger crater I see in the photos taken by NASA that Phobos was a good candidate for that source material. Another question or comment. Perhaps some of the meteorites of different classes sample the same asteroid (or family, clan). We could have iron meteorites, pallasites and chondrites or achondrites all from the same parent body but we are looking at different depths of material all from the same parent body or asteroid family clan. This is no doubt true of the meteorites we have from Vesta and shows material from different depths.

Hello All, This is my first shameless plug for a listing of goodies for sale and due tomorrow night on ebay. Tonight will be the long version. The list has a couple meteorite slices including Gao, Dhofar 007 and NWA 904. http://members.ebay.com/aboutme/herman-75/ I've also added some nice earthly material (olivinegabbro) which I liken to achondrites such as shergottite and diogenite.I'velisted a few slices that are a cheap version of a nice slice ofthe good stuff. I know many of you could care less about such material, but I feel compelled to share what I think is great study material. Especially when comparing to achondrites.Based on its location in the field, this material isprobably ancient ocean bedrock from the Pre-Cambriantime period, and maybe over a billion years old.I would like to think if we ever find meteorites on the moon from earth, it would be material similar to this. I also have listeda piece of magnetite rich gneiss (iron ore) which is stongly attracted to magnets. In the future I will also have more meteorites, thin sections of meteorites and gabbros, etc, and other types of earthly finds from the same area including peridotite, serpentenite, hypersthene-magnetite rich material, gneiss(es), etc. If any of you are interested in getting some of this great earthly material, contact me and I'm sure I could fix you up fora small price plus shipping. All of the material was field collected by me. Take care and thanx for reading. John Divelbiss Reading, PA IMCA 2006

Bernd, Matteo and Brothers and Sisters of this list, One year ago our country was savagely and cowardly attacked. It was my first experience of a so-called war that hit me close to home. I did not lose a family member or friend, but I cried just the same. Living here in the middle of the 3 sites of the crashes was scary. The horrors we all witnessed were reminders to me of my grandfather's stories of the trench battles, and the great pain and suffering of WW 1. He left us last November at 106. He always felt war was such a waste, but yet he was very patriotic and supported our countries efforts to stop others from creating such terror and grief. My father's stories of WW 2 were just as disturbing...he even had horrific pictures that a friend of his took of the concentration camps. Vietnam is a nightmare for many. All countires involved in these wars can attest to the horror. People can be so cruel. Let us not forget that fateful day last year. We all have to be diligent in our daily lives, and possibly one day have to pay the great sacrifice to stop the evil. I am ready if such an occurrence would present itself.

Re: [meteorite-list] Bessey comment
Ron and associates, Greetings. First off, I know you have along distinguished career in this arena and I wish to not offend you and others who have given so much to this great interest of many. My frustration is the long list of Sahara and NWA numbers that do not have official classifications including weights, etc. As Mark Mafer suggested there must be ways to help this process out by using a simpler method of classification for ordinary chondrites. It would not be the full blown method, butareduced method that at least would label/categorize many of the unknowns. Is that possible? Make it a special label as "probable" or something like that. I can make guesses, but I'm sure my accuracy would be poor. I believe Dean when he says he has triedwith difficulty to get classifications. Maybe at this point(due to frustration) he is just passing the burden on to others to keep his business going. Isit a lack of effort or is there one big roadblock, that only opens for the achondrites and the #3 chondrites. I don't know...but what I do know is that the list ofofficial meteorites is short compared to the amount of material outthere. As for the article, yes I read it this week and it sounds very simple to get a #. Who would someone like mecontact, andwhatare the odds of getting a classification? A number withoutofficial (even if probable) classification is nothelpful in my opinion. I mean if I go to the trouble of sending in something, only to end up with a number...what is the point?I can label it I guess. I will try myself in near future to get a classification on an unknown...and report back with my experience.

I have no clue as to the fix(es) for the problems perceived, but to "putoff or shun" the likes of Dean and others to get classifications done in a timely matter is a mistake. Some dealers have direct connections that make this less of a problem...but they are in the minority I would think. A concerted effort to improve all aspects of this problem, including the availability of labs capable of doing such work should be done before we lose the bulk of potential information on these great rocks. It is late in the game, but not too late I would hope. There are many great pieces out here that are orphaned at this point...with owners wanting to know what it is.

Re: [meteorite-list] Bessey comment
Bernd, Dave and list, I concur with the comments to date. But I thought it really wasn't meteorite until the council says it is? For now it is just a rock, right. My gut tells me that science as a whole is missing the boat with the NWA's...someday the negative positions taken during these times over the lack information like location, particulars of find, etc. will be a mistake that can't be fixed. I know this subject has had a lot of press, but from a simpletons point of view the treatment of the most NWA's not being legitimate is wrong. I have no clue as to the fix(es) for the problems perceived, but to putoff or shun the likes of Dean and others to get classifications done in a timely matter is a mistake. Some dealers have direct connections that make this less of a problem...but they are in the minority I would think. A concerted effort to improve all aspects of this problem, including the availability of labs capable of doing such work should be done before we lose the bulk of potential information on these great rocks. It is late in the game, but not too late I would hope. There are many great pieces out here that are orphaned at this point...with owners wanting to know what it is. Protesting not to buy or acknowledge this so called junk only reinforces this stubborn position. Those doing so are adding to the thick crust of the objectors...limiting science instead of improving it. From the sounds of it, fixing the problems (some real, some perceived due to association) in Morocco are probably the hardest to resolve...and they may never be.

I am newbie to all this, collecting only for three years. I'm sure many smart people out there have more insight. But when you break it down in my mind, the general treatment of NWA's (and other African meteorites) is WRONG!

Re: [meteorite-list] Beginner Questions on Meteorite Classification
Mark, If you look hard you will find dozens of decent sites that will help one understand meteorites alot better. Also, Nortons new book goes alot further than Rocks From Space, and it is filled with colored pictures demonstrating the differences in their appearance. It is called The Cambridge Encylcopedia of Meteorites, and is highly recommended. Another very in depth book is Meteorites and Their Parent Planets by Harry McSween, Jr. To read it and understand (most of) it takes great patience and focus...good luck. Another interesting (online) source of information and pictures is the Dweir Studies. The link to it is below. There are other books, sites that others may refer you to that are helpful. http://www.geocities.com/~dweir/ Have fun...it takes awhile to get the full depth.

[meteorite-list] impact melts and mesosiderites
Hello all, I want to ask the group their opinion on whether they agree with the latest book from Norton that places mesosiderites in the achondrite section, rather than the stony-iron section of the book. As I understand it, he "suggests" that mesosiderites are merely impact melts of the howardite/eucrite parent body with an iron body. Similar to H and L impact melts. Personally, I agree with this concept after comparingChico (L6 IMB), Sahara98362 (H6 IMB) and the new Gao (b) (H5? IMB) with slices of mesosiderites Vaca Muerta and Ethersville. Vaca Muerta looks like the H and L IMB's, while the Ethersville I have has larger pockets of metal than the others...but similar to some of "normal"Gao I have. Willmesosiderites one day be renamed Howarditeimpact melts or Eucrite impact melts? I may be going too fast here, but the suggestion in the Norton book leads a novice like me down that path. Wondering??? John Divelbiss Reading, PA IMCA 2006

Re: [meteorite-list] Springfield Show this weekend!
List, I was at the Springfield Show this past Friday. Being my first show, I was very interested in seeing some nice material first hand. The balance of meteorites available to the rest of the show's materials was very small, but we were not without great representation of dealers, collectors and ofcourse the rocks. At the invite of fellow collectors, Charlie Devine and Gary Swanson from Rhode Island, I traveled the 6 + hours from PA in anticipation. My first encounter when the doors opened was with thehumble Alain Carion. He was very interested in discussing and selling his beautiful selection of meteorites and impactite. Getting my copy of his book signedwas a treat.I ended up getting some his Tafassasset, a CR equilibrated to a6 or 7, so the chondrite believers say. However, he mentioned that others argue it is primative (achondrite). But Alain assured us thatit was primative, as in a chondrite. Awonderful transition type...one of a kind I believe ? I also picked up a fragment of the microtektite material from Haiti...very nice. Alain, thank you for your time (Ann Black, please let him know if you would). Others there included Geoff Cintron from Island Meteorites. Geoff had some awesome pieces for sale and a nice chunk of Murchinson was my prize. Thanx for the opportunity, and to be able to hold and look at some choice material. Geoff carries the flag well. The other main dealer was Serg from Comet Meteorite Shop who have some great stuff, including the Dhofar lunars and shergottites. The NWA 470 (?) was one I was interested in, their CH...but I came up short. Maybe someday. Thanx for the look see Serg. A fair amount of Sikhote Alin's were seen at several stands, and some of the newer Campos were available from the field collectors. It would be nice to see more dealers next year. Maybe more interest and feedback will bring them. Well thanx to Charlie and Gary for their interest in me. It was a great day.

Re: [meteorite-list] Posted on Sci.astro.amateur what is it?
Tom, Looks like a slag from a smelting process. Probably the lighter material from the top of the process. If you see that someone buys it, I can find some more for them here in PA. The hills are full of it. The magnetic property is probably due to the rock being melted having magnetite in it. I once thought that some slag I found was possibly a meteorite.

Adam, Thanx for response. Now that's two votes for 787, 869 and 900 pairings. As far as 904 goes...it does look similar, and it does have melt inclusions, like others. But the diogenite (which I have not seen or heard of in others, yet) and the crust that you said is just plain ugly, make them different in at least two ways. I know the crust is ugly because I have a nice end piece. With those two items in mind I'll agree that 904 is not paired with the others. But again it is only my opinion here agreeing with you.

Although the chondrules vary in crispness from type 3 to 6 most of them are type 5. D.) The crust is totally different than 869 and 900, is not as fresh and has a rather odd warty texture. F.) The green diogenite looking clasts are achondritic. G.) NWA 904 has different zones which show different degrees of weathering and petrologic type. H.) I have a sample of NWA 869 and have seen hundreds of kilos of it at the Tucson Gem and Mineral Show and it is not paired with NWA 904. I.) NWA 869 looks as if it might be paired to NWA 787, a very nice looking L6. J.) NWA 869 has had three different classifications L4, L5 and L6. I guess it depends on the type samples that were provided to the laboratories. I do not blame the research labs because most dealers only deposit a 20 gram type sample. Sometimes this amount of material is not enough to cross the different petrologic boundaries and thus you can get many classifications for the same meteorite. Some dealers only send in a portion which they think will get the best classification, sharp chondrules, less weathering etc.. K.) Although NWA 900 has black clasts it does not display the zoning of NWA 904, has no green clasts and the weathering is consistent throughout the stone. L.) In my opinion NWA 787, 869 and 900 are paired. I have not seen NWA 995 so I cannot comment on its pairing status. If we had more time we would do a bulk analysis on each of these to once and for all settle the pairing question. Unfortunately the Microprobe we lease is booked until September.

Re: [meteorite-list] nwa869
Hi Al and list, Thank you again for being attentive to my ramblings. You and countless others are close to, and more informed of the process and the expertise given to the analysis of meteorites. I did not mean to trivialize this process...and if I did offend anyone, I'm sorry. My nature, being a mechanical consulting engineer, is to evaluate all situations with a bit of skepticism and caution. It comes through on occasion with my meteorite collection. So does my ignorance on the subject, but I'm learning. As far as looks go when evaluating a particular piece, or when comparing one to another...well that's all I've got, and the word of the seller and it's evaluator. In the case the NWA's, the collection process as you mentioned makes the identification process that much harder to be sure of a given class/type. In the case of 869 and all its brother and sister #'s...I would like to see a concerted effort to nail this one down. The wonderful 900 slices from Matteo deserve it, along with the unique 869 pieces Dean and Mark have seen and offered with nice C clasts and brecciation, the same for 995 slices sold last winter, and let us not forget the beautiful slices of 904 and others (787 I believe) from the Hupes. All of these, and others as Matteo suggested deserve an opinion of are they from the same fall or source?. I would appreciate it, and I'm sure many others would also. How it would get done is a mystery to me. Maybe it could be project for a university to study and comment on. How about it Ron? Well I'm going to stop embarrassing myself on this one.

Today using the microprobe for chemical analysis, scientists are looking at about ten different items and trace chemical signatures to distinguish the minute variation of the common chondrites. To further help this out and isolate it more, the shock metamorphism is also taken into consideration. Although no process is perfect I think there is a pretty good handle on being able to distinguish individual falls these days using the processes stated. Also weathering comes into play on these. With that said, I would think the bigger problem on a fall coming out of the Sahara desert is whether some nomad decided to throw (or perhaps the rocks just get mixed up in camel transit) into the lot and so we have a mixture of different falls stated to be from one fall. As with meteorite dealers it is a matter of trust on whom you are dealing with and if they are being honest with you or not. This isn't meant to be a grind to those going over there an collecting these items. I don't think it is always a good idea to go by looks on meteorites (I have many in my collection that are similar in appearance but from discrete falls and finds) and until a detail analysis is done then it is really hard to say. As a rule with time when these meteorites are looked at they may refine the classification. With the break up of Hebe and back into a rubble pile we sample a variation of classes in a single chondrite sometimes. I trust the researchers to be able to distinguish the bulk matrix of these finds and produce a accurate classification. It is to their own advantage when they do research on these to know the accuracy of classification on the meteorites they are dealing with so they don't go the wrong direction on understanding them. All my best! --AL John Divelbiss wrote: I just looked at the group I have and quite frankly it is not easy to say they are different materials. Even under the scope.

Thin sections of each one may help...but as Dean has stated, his section may have thrown off the evaluation of his sample relative to its true petrologic type. All this makes me wonder about the process and accuracy of identifying a particular fall or find. As I understand it, the boundaries between H's and L's can be somewhat blurred when metal and iron contents are in the transition percentage levels.

Re: [meteorite-list] nwa869
Hello List, I'm probably wrong here, so please help me out here. Lets get it out open for everyone...which ones are we talking about here that maybe paired with 869. I've been wondering about this group for awhile now. NWA 869 paired with NWA 900 ? NWA 904 ? NWA 905 ? Are there others that might match up? At times, I think NWA 787 (L6) looks like a close (differentiated) cousin to 869. Could a large enough meteor have all these petrological possibilities within different zones of the original large mass (prior to breaking up)... in theory I suppose. One piece looking like an L5 or L6, and another L3/4.4 (Matteo is this correct for yours...and which NWA # of yours is it?) Zag comes to mind being a H3-6. Obviously this mean that some chondrules are 3's and others are differentiated all the way to 6. Can you see these differences in one slice or is it different from piece to piece? Could that the same for 869 and its brothers? By the way...I have pieces (NWA's) of all the above, and I think each one is very nice material and at first glance they look about the same. Crusts are slightly different in some cases...but could that be from the desert effects in different locales?

For $230 I will cut the kilo of specimens in two or for $300 a kilo I will cut you 40 to 60 gram (On Average) slices (And of course the two endpieces per stone). No guarantees of anything unusual but I will send you a photo of the uncut specimens as they looked before I cut them so that I cant cherry pick them and decide after I cut them which ones to send you - so you would have as much a chance to get the inclusion looking things as if you cut them yourself. Just paypal me if you want them as I have plenty to fill any orders. I will cover postage to the US (which cost $11) but other countries add $15 for postage (Which cost about $26 to $28 so I am getting the same price no matter where they are being sent) Cheers DEAN _ You dont have to go to NASA to get a Rock from outer space.

Re: [meteorite-list] nwa869
Al, Your point is well taken on the source aspect of this discussion. As with any type, no matter the name or number assigned to it...there is good chance they are from the same asteroid. HED's from Vesta, etc. I just looked at the group I have and quite frankly it is not easy to say they are different materials. Even under the scope. Yet I see the reports of L4 or L5 for NWA 869, L6 for 787, now L3.4/4 for 900, and similar suspicions for 995 (not 905 that I listed in earlier message). Thin sections of each one may help...but as Dean has stated, his section may have thrown off the evaluation of his sample relative to its true petrologic type. All this makes me wonder about the process and accuracy of identifying a particular fall or find. As I understand it, the boundaries between H's and L's can be somewhat blurred when metal and iron contents are in the transition percentage levels. All the more bewildering. I'm glad I'm not assigning these things. How does one know when he or she has got it right? Personally I'm going like them all for being rocks from space. With that in mind is seems silly to argue between one fall or # versus another with mine is different than yours... when at first look they do not appear to be any different. I will however be cautious of paying too much for so called petrological type of 3's and 4's when it isn't obvious. I'll stick with do I like it or want it or not, relative to the price it is offered at ?.

However there are some suspect parent bodies which have been identified by spectral matches to the asteroids and meteorites. One such match is asteroid Hebe for the H type chondrites. It is obvious from looking at Hebe's surface that it has a variation in spectra as the asteroid rotates representing the different metamorphism (classes) we see from the change in olivine to pyroxene ratio. No doubt the asteroid had a large enough impact at one time to knock it apart allowing the more differentiated classes to show up on the outside, and some of the outer part of the asteroid became buried in the interior as it reassembled into a rubble pile asteroid. It isn't uncommon for H type chondrites to have brecciation of various different classes all in one meteorite. A good example of this is Zag (H3-6) and Noblesville, Indiana an H4 chondrite with H6 clasts. Probably why we get so many of the H type chondrite material now is we are living at a time when the results of the impacts which have been migrating to us over the eons have finally made their way to fall at a constant rate. If we lived in a different time many years from now or very long ago then perhaps and most likely we would sample some other type of meteorite falls. Perhaps it wouldn't be uncommon for some rare type meteorite (to us) to fall at a regular more consistent rate. How does this tie into NWA 869. As stated earlier we don't know all of the parent bodies yet (a good reason for funding to NASA to build a craft to visit as many asteroids as we can) However there is one asteroid of about 7 km in diameter that resides in the main belt and may be related to the L type chondrites and a possible parent body though a very weak link. Asteroid 3628 Boznemcova exhibits spectral qualities to the L's and LL's. It is obviously too small to be a complete asteroid and has been suggested it is a fragment of a much larger asteroid. Perhaps this might be what is left of the NWA 869 and other L type meteorites and why we sample a steady rate of L type chondrites. Beside these parent bodies, we are fairly sure of the Vesta and HED type meteorite connections as well as the Martian (SNC), and lunar meteorite to Moon connections. It's what makes reading about and research on meteorites so exciting and trying to figure out all of the complicated puzzles they present to us. --AL Mitterling __ Meteorite-list mailing list [EMAIL PROTECTED] http://www.pairlist.net/mailman/listinfo/meteorite-list
Re: [meteorite-list] Which meteorite is real - top or bottom?
Tim, I'll guess the bottom one is a real meteorite. Maybe a 1947 SA? The top specimen looks too roundish. Hematite ore or something like it? Hey...50/50 chance. John Divelbiss IMCA #2006 PS The 102 F (in the shade) we had here in Eastern Pennsylvania yesterday was not a dry heat. WOW! At least we finally got a break today...below 90 F. Hope all of you out West get a break soon. And hopefully it gets above 70 F for you guys in Europe. Take care all. - Original Message - From: Tim Heitz [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Friday, July 05, 2002 2:06 AM Subject: [meteorite-list] Which meteorite is real - top or bottom?

Re: [meteorite-list] Interesting meteorites- Portales and Sahara 98362
To answer one of my own questions...I can offer this...impact melts are just what the name suggests, two materials that have collided, melted and cooled together. Probably on or near the surface??? Portales being from a "deep" region, is a combination of two materials that were joined by shock and pressure injection(of metal into stone). Temperature must not been a major factor for the depth. Could a Portales and a Sahara 98362 have formed in the same type of collision? I would like more input on the particulars of 98362, if possible.

I have a wonderfulpiece that has a nice mix of metal vein and stone...including a few large chondrulesright next to a metal vein. Very strange...you would think such an impact would alter the stone greatly...but it doesn't look like it at first glance. Also the crust over the metal portion is black and not thick. The crust over the stone portion is similar but has the look of having more minerals in it. With my small 5g piece, I cannot make too many observations. That brings me to a different meteorite. It is Sahara 98362, which is supposedly a H6, impact melt breccia (IMB). My first question is"Has it been thoroughly studied, and where can I find results?" The second issue...what is difference between animpact melt and what happended to the Portales stone material?One hit by stone and the other hit by an iron? It must be more than that, because the 98362 material is glass-like when viewing a fractured surface. It is loaded with metal. I seen no other meteorite like it. It looks almost like the sulphur slag that has been discussed lately. Help...will someone please provide more insight into this very strange meteorite? Thanx in advance, John Divelbiss

[meteorite-list] African meteorites
Hello All, Being my first week on "the list", I'll give you all my take on why "African Meteorites are cool because." great pieces of LUNAs SNCs CRs HEDs LLs COs Rs and the occasional unclassified individual (that could be one of above if I chose to cut it!) ...all adorn my collection without breaking the bank. It has been a great time to collect during the past couple years. The African meteorties have been a blessingto the common working man/collector. Enjoy them, JohnDivelbiss
