[meteorite-list] I want to display a Canyon Diablo piece in the local Library
Hello List, Now that Montrose, Colorado is no longer the Meteorite Capitol of the World or whatever, I have something I would like to do. I have a 733 gram whole individual Canyon Diablo iron that I want to display in the same display case at the Montrose Regional Library where some other supposed moon rocks were displayed a while back. I would like to display this piece of iron in hopes that it might, on its own, spark some interest in meteorites, and maybe the write-up that I put with it will help as well. My piece is not that spectacular but since it is all I have, hopefully it will work. I got this piece from a fellow up in Oregon that traded the finder for it back in the 1970s. The finder responded to my inquiry on the piece basically acknowledging the piece but I think I still need a certificate of authenticity in order to properly display it as a meteorite. My questions to the M-List are: how can I get a certificate on it; and would anyone want to suggest information on the Canyon Diablo irons that I should put with it in the display . I am willing to send the piece I have off to a lab if necessary to get it certified but to who? I would like to get it into the display case yet this winter if that's possible. I would appreciate any and all help I get on this. Here is a picture of the iron that I have: http://i127.photobucket.com/albums/p124/mmurray_02/IMG_1697.jpg Mike __ Visit the Archives at http://www.meteorite-list-archives.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list

Re: [meteorite-list] Giant Asteroid's Troughs Suggest Stunted Planet
Is it possible they could be a result of the giant impact? Ripples maybe? On Sep 26, 2012, at 6:03 PM, Ron Baalke wrote: http://www.jpl.nasa.gov/news/news.php?release=2012-304 Giant Asteroid's Troughs Suggest Stunted Planet Jet Propulsion Laboratory September 26, 2012 Enormous troughs that wrap around the giant asteroid Vesta may actually be dropped blocks of terrain bounded by fault lines, suggesting a geologic complexity beyond that of most asteroids. Since the discovery of the troughs last year in data from NASA's Dawn spacecraft, scientists have been working to determine the story behind these unusual features. The research reinforces the claim that Vesta has a core, mantle and crust, a structure normally reserved for larger bodies, such as planets and large moons. An extensive system of troughs encircles Vesta's equatorial region. The biggest of those troughs, named Divalia Fossa, surpasses the size of the Grand Canyon. It spans 289 miles (465 kilometers) in length, 13.6 miles (22 kilometers) in width and 3 miles (5 kilometers) in depth. The complexity of the troughs' morphology can't be explained by small collisions. New measurements from Dawn indicate that a large collision could have created the asteroid's troughs, said Debra Buczkowski, a Dawn participating scientist based at the Johns Hopkins University Applied Physics Laboratory in Laurel, Md., who is the lead author of a new paper in Geophysical Research Letters, a journal of the American Geophysical Union. The crustal layer at the surface appeared to stretch to the breaking point and large portions of the crust dropped down along two faults on either side of the downward-moving block, leaving the giant troughs we see today. The scale of the fracturing would only have been possible if the asteroid is differentiated - meaning that it has a core, mantle and crust. By saying it's differentiated, said Buczkowski, we're basically saying Vesta was a little planet trying to happen.

The findings were presented today at the annual meeting of the Geological Society of America in Minneapolis, Minn. Dawn, which has been orbiting Vesta since mid-July, has found that the asteroid's southern hemisphere boasts one of the largest mountains in the solar system. Other findings show that Vesta's surface, viewed by Dawn at different wavelengths, has striking diversity in its composition, particularly around craters. Science findings also include an in-depth analysis of a set of equatorial troughs on Vesta and a closer look at the object's intriguing craters. The surface appears to be much rougher than most asteroids in the main asteroid belt. In addition, preliminary dates from a method that uses the number of craters indicate that areas in the southern hemisphere are as young as 1 billion to 2 billion years old, much younger than areas in the north. Scientists do not yet understand how all the features on Vesta's surface formed, but they did announce today, after analysis of northern and southern troughs, that results are consistent with models of fracture formation due to giant impact. Since July, the Dawn spacecraft has been spiraling closer and closer to Vesta, moving in to get better and better views of the surface. In early August, the spacecraft reached an orbital altitude of 1,700 miles (2,700 kilometers) and mapped most of the sunlit surface, during survey orbit, with its framing camera and visible and infrared mapping spectrometer. That phase was completed in late August, and the spacecraft began moving in to what is known as High Altitude Mapping Orbit at about 420 miles (680 kilometers) above Vesta, which it reached on Sept. 29. An archive of the live news conference is available for viewing at: http://www.ustream.tv/nasajpl2 . The Dawn scientists also shared their findings at the recent European Planetary Science Congress and the Division of Planetary Sciences Joint Meeting 2011 in Nantes, France. Dawn launched in September 2007 and arrived at Vesta on July 15, 2011. Following a year at Vesta, the spacecraft will depart in July 2012 for the dwarf planet Ceres, where it will arrive in 2015. Dawn's mission to Vesta and Ceres is managed by the Jet Propulsion Laboratory, Pasadena, Calif., for NASA's Science Mission Directorate in Washington.

The data obtained by Dawn's framing camera, used to produce the visualizations, will help scientists determine the processes that formed Vesta's striking features. It will also help Dawn mission fans all over the world visualize this mysterious world, which is the second most massive object in the main asteroid belt. The video, which shows Vesta as seen from Dawn's perspective, can be viewed at: http://www.jpl.nasa.gov/video/index.cfm?id=1020. You'll notice in the video that Vesta is not entirely lit up. There is no light in the high northern latitudes because, like Earth, Vesta has seasons. Currently it is northern winter on Vesta, and the northern polar region is in perpetual darkness. When we view Vesta's rotation from above the south pole, half is in darkness simply because half of Vesta is in daylight and half is in the darkness of night . Another distinct feature seen in the video is a massive circular structure in the south pole region. Scientists were particularly eager to see this area close-up, since NASA's Hubble Space Telescope first detected it years ago. The circular structure, or depression, is several hundreds of miles, or kilometers, wide, with cliffs that are also several miles high. One impressive mountain in the center of the depression rises approximately 9 miles (15 kilometers) above the base of this depression, making it one of the highest elevations on all known bodies with solid surfaces in the solar system. The collection of images, obtained when Dawn was about 1,700 miles (2,700 kilometers) above Vesta's surface, was used to determine its rotational axis and a system of latitude and longitude coordinates. One of the first tasks tackled by the Dawn science team was to determine the precise orientation of Vesta's rotation axis relative to the celestial sphere. The zero-longitude, or prime meridian, of Vesta was defined by the science team using a tiny crater about 1,640 feet (500 meters) in diameter, which they named Claudia, after a Roman woman during the second century B.C. Dawn's craters will be named after the vestal virgins-the priestesses of the goddess Vesta, and famous Roman women, while other features will be named for festivals and towns of that era.

The magnesium/silicon, aluminum/silicon, and calcium/silicon ratios averaged over large areas of the planet's surface show that, unlike the surface of the Moon, Mercury's surface is not dominated by feldspar-rich rocks. XRS observations have also revealed substantial amounts of sulfur at Mercury's surface, lending support to prior suggestions from ground- based telescopic spectral observations that sulfide minerals are present. This discovery suggests that the original building blocks from which Mercury was assembled may have been less oxidized than those that formed the other terrestrial planets, and it has potentially important implications for understanding the nature of volcanism on Mercury.

Re: [meteorite-list] Does Asteroid Vesta Have a Moon?
I would bet the excitement is really starting to build for the people working on this mission. Shouldn't be long now until they can figure out what Vesta is made up of. Congratulations to everyone involved. Mike in CO On Jul 7, 2011, at 11:07 AM, Ron Baalke wrote: http://science.nasa.gov/science-news/science-at-nasa/2011/06jul_vestamoon/ Does Asteroid Vesta Have a Moon? NASA Science News July 6, 2011 July 6, 2011: NASA's Dawn spacecraft is closing in on Vesta, and from now until the ion-powered spacecraft goes into orbit in mid-July, every picture of the giant asteroid will be the best one ever taken. What will researchers do with this unprecedented clarity? For starters, says Dawn chief engineer Marc Rayman, we're going to look for an asteroid moon. You might think of asteroids as isolated bodies tumbling alone through space, but it's entirely possible for these old loners to have companions. Indeed, 19-mile-wide Ida, 90-mile-wide Pulcova, 103-mile-wide Kalliope, and 135-mile-wide Eugenia each have a moon. And 175-mile-wide Sylvia has two moons. Measuring 330 miles across, Vesta is much larger than these other examples, so a Vesta moon is entirely possible. Where do such moons come from? Rayman suggests one source: When another large body collides with an asteroid, the resulting debris is sprayed into orbit around the asteroid and can gradually collapse to form a moon. Another possibility is gravitational pinball: A moon formed elsewhere in the asteroid belt might, through complicated gravitational interactions with various bodies, end up captured by the gravity of one of them. Hubble and ground based telescopes have looked for Vesta moons before, and seen nothing. Dawn is about to be in position for a closer look. This Saturday, July 9th, just one week before Dawn goes into orbit around Vesta, the moon hunt will commence. The cameras will begin taking images of the space surrounding the asteroid, looking for suspicious specks. If a moon is there, it will appear as a dot that moves around Vesta in successive images as opposed to remaining fixed, like background stars, says Dawn Co-investigator Mark Sykes, who is also director of the Planetary Science Institute. We'll be able to use short exposures to detect moons as small as 27 meters in diameter. If our longer exposures aren't washed out by the glare of nearby Vesta, we'll be able to detect moons only a few meters in diameter. While you won't see find a moon among the mission's science goals, a moon-sighting would be a nice feather in Dawn's cap. Not that it will need more feathers. The probe is already primed to build global maps and take detailed images of the asteroid's surface, reveal the fine points of its topography, and catalog the minerals and elements present there. Besides, Dawn will become a moon itself when it enters orbit around Vesta. And the probe's motions as it circles will provide a lot of information about the rocky relic. Sykes explains: We'll use the spacecraft's radio signal to measure its motion around Vesta. This will give us a lot of detailed information about the asteroid's gravitational field. We'll learn about Vesta's mass and interior structure, including its core and potential mascons (lumpy concentrations of mass). As you read this, the spacecraft is gently thrusting closer to its target. And with the navigation images alone we're already watching a never-before-seen world grow ever larger and clearer. The pictures are beginning to reveal the surface of this battered, alien world, says Rayman. They're more than enough to tantalize us. We've been in flight for four years, we've been planning the mission for a decade, and people have been looking at Vesta in the night sky for two centuries. Now, finally, we're coming close up to it, and we'll be getting an intimate view of this place. This is not only the first time a spacecraft has visited this alien world, it's also the first time a spacecraft has visited a massive body we haven't approached previously. In the past, rocket ships have orbited Earth, the moon, Mars, Venus, Jupiter, Saturn, and Mercury. In each case, flyby missions occurred first, providing a good estimate of the target's gravity along with information on other aspects of its physical environment, including whether any moons are present. This time we're much less certain what we'll find. At a recent press conference, NASA Planetary Science Deputy Director Jim Adams told reporters that Dawn will paint a face on a world seen only as a 'fuzzy blob' up to now. What does Rayman think Vesta's face will look like? Wrinkled, ancient, wizened, with a tremendous amount of character that bears witness to some fascinating episodes in the solar system's history. If a new moon is among the episodes, Rayman has a name in mind. How about 'Dawn'? Author: Dauna Coulter Editor: Dr. Tony Phillips Credit: Science@NASA More

Re: [meteorite-list] non-magnetic meteorites?
I have a small suspect stone that will roll right off of a NDIB supermagnet if you set it on it and tilt the magnet a little, but I picked it up with my magnet cane. (??) I have two 2x2x1/4 NDIB supermagnets side by side on the head of the cane. When I found the little stone that day it was sitting up on the top of the magnets and right in the middle where the two magnets touched. I don't know squat about magnets but because of finding this little rock like that I have always wondered if the attraction is stronger when two flat magnets are touching each other on the edge more so than just one of those magnet's attraction by itself. I'm probably way out in left field on this. Maybe someone on the List can shoot down my theory so I can forget about that being the reason for picking up the stone.

[meteorite-list] Saw another fireball a little bit ago
We need an all-sky camera in my neck of the woods... I just saw another (small) fireball. It was orange/red. I first saw it a little to the west of Montrose at about 45 to 50 degrees above the horizon and it appeared to be on a path almost due north. It traveled until I would say it was at 10 to 15 degrees above the horizon from my view point, then looked to have disrupted and then quickly went dark. No sound from it that I could hear but that's not saying much because I have tinnitus terrible bad tonight. My wife had called me to come outside to listen to a really high pitched sound she could hear when she was on the north side of the house. Turned out to be an alarm going off in our 5th wheel sitting in the driveway. As I was standing out there in the front drive trying to figure out that sound, that is when I saw the fireball.

[meteorite-list] green fireball last night
I email Cloudbait Observatory about this. We were driving home last night when we saw a green fireball going west from here (southwest Colorado). Looked like it was headed out over Utah, maybe farther. Anyone else see it? Time was about 10:10 PM.

Hi Chris, List I for one, certainly appreciate your opinions. I have a great deal of respect for your knowledge and abilities. I'm glad you're willing to share the things you do with the List. I would miss it if you didn't. If I haven't thanked you before for the things you share, I will now. Thank you. And I mean that sincerely. List, hopefully we have reviewed at least my original post about the use of the rods all we need to. I have had someone contact me who did not elaborate but their wish was for me to stop please. I presume they are wanting fewer emails. I intend to respect that wish at least on this topic. I don't know exactly where the thread is off to now. Because I don't think some of what I see now being brought up actually pertains to my first post exactly. I believe I will have to relinquish responsibility for the thread at this juncture. I will apologize now for any headaches the number of emails to this point has caused anyone. However I must admit, I have enjoyed the discussion immensely.

Re: [meteorite-list] Divining and dowsing-a question
I'm somewhat surprised that the Met-List doesn't have at least one or two other folks on it that work or have worked in one of the utility businesses dealing with underground utilities or for that matter someone in the landscaping business. If they are on the List, they are sure being kind of quiet. What ever name you want to put on using the rods, divining, dowsing, who cares, they are used quite a bit in both types of businesses. I have even seen municipal workers using them to locate their own stuff underground. Wow, imagine that, sure a lot of good folks out there using bullshit to maintain your underground utilities. Someone aught to clue 'em in, eh? Just be prepared anyone doing the cluing, you might want to back up a bit when you tell them that their efforts to keep from hitting your power, water, sewer or whatever prior to excavation is nothing more than bullshit.

[meteorite-list] Try divining rods over a large iron
List, If someone out there with a baseball size or larger iron wouldn't mind performing a little test with it I would appreciate hearing back from them on how it turned out. To test what I had in mind you will need to make a couple metal divining rods out of coat hangers or something similar. Starting with an overall length of wire about 24 inches, make a 90 degree bend at about 6 inches from one end. Hold the short ends vertical, one in each hand and keep the long part close to horizontal and move over the iron. Do this some place away from any other metals and in an area where you don't get movement on the rods otherwise. What I'd like to know is, when you do move them over the iron meteorite, do they try to cross? Can you get movement on the rods if you are standing up and the meteorite is on the ground? If not, how close to you need to have the rods from the iron? Thanks in advance to anyone giving this a try for me.

[meteorite-list] very small possible
Hi List, Hope you don't all throw me on the crazies pile after you read this but here goes... It was August 17 at approximately 7:15 PM. My wife Beverly and I were working on freezing some corn late in the afternoon. Earlier, I had picked about 4 dozen ears out of the garden. I had husked it on the back deck and was carrying the second sack of husks back out to the compost pile in the garden. As I was approaching the east most edge of the lawn next to the garden, I saw a very small object dropping quickly down at a slight angle in front of me at about an arm's length away. I continued on into the garden but as I was dumping the husks out of the sack, I was thinking about what I had just seen. I decided I would go get my big magnet rake and run it over the grass in that spot where the object had come down. Maybe it wasn’t a bird drop or an insect. It sure seemed to be traveling in a straight line as it fell. It had me thinking possible meteorite. I walked back out there with the magnet rake and drug it in two different directions over the area. Then I carefully picked the rake up and carried it across the lawn over to a plastic table by the east end of the house and set it up on it. It was getting late in the day and I needed to cut the front grass yet, so I hopped on the mower and got it cut. I was also going to cut a small area out back so I headed out there. I started to make a pass around that area when the mower picked up a short piece of nylon rope I had left laying in the grass. I shut the pto off and decided time to call it quits for the night and went back to the garage with the mower. After putting the mower away, I grabbed a small gold pan off a shelf in the garage and headed back out to the the magnet rake. Working carefully, I cleaned the magnets off real good putting everything I got off of them into the gold pan. I put the magnet rake away and took the gold pan with its contents in the house to look at the little bits through the microscope. After taking a seat at the scope, I shook the pan in a manner that could be likened in the gold panning world to the Blueberry Bounce. That action allowed me to separate the very small bits from the more coarse pieces in the pan. There was less than a half teaspoon of dry fine stuff all total in the pan so not a lot of material over all. With the really fine stuff out of the way, I started checking over the little rock pieces one by one using the low-power scope. As I searched through the pan and using a pair of plastic tweezers, I took four little bitty rocks out that looked like they might be possibles. I put them on a small child security magnet. My wife walked into the room about that time and I told her about my seeing something very small fall in front of me when I was heading back out to the garden. I explained that I was experimenting. I wanted to see if by chance my supermagnets could have picked it up. Back to the scope now, I inserted the 20x eyepieces and turned up the magnification on those 4 little pieces I had placed on the magnet. Bringing them into focus and looking at the third stone there it was! A small dark brown/black object that looks very much like a stony. I said out loud to Bev, “There it it is!” She had been on the computer right next to me so I asked her to come over and take a look at it through the scope. She did. “Oh, yeah. Wow!”, she said as she studied it. After she got up from the scope and walked back out into the living room, I sat back down and marveled at it through the scope again for a bit. Certainly not for it's size but because of the high possibility that I may have just recovered a stony meteorite I had seen fall. Then the thought struck me...If it is the same small object I saw fall and it is actually a stony meteorite, chances are it will have a sulphur smell. I cleaned the magnet off so that it was on there by itself and held it up close to my nose. Yep, smells like sulphur. Without saying anything about what I had just smelled, I took the magnet with the stone on it out to the living room and asked Bev to put it up close to her nose to smell. She did and she said, “Oh, it smells like sulphur!” I took it off the magnet and placed it in a small vial. It's about the thickness of pencil lead so very hard to photograph but here are a couple poor quality pictures anyway. Maybe someone out there has the ability to brighten up the photos. I don't have much of a photo program and wasn't successful trying to brighten them up. http://i127.photobucket.com/albums/p124/mmurray_02/fallpic2.jpg http://i127.photobucket.com/albums/p124/mmurray_02/fall.jpg Mike in CO __ Visit the Archives at http://www.meteoritecentral.com/mailing-list-archives.html Meteorite-list mailing list
[meteorite-list] I know what it looks like...
Hi List, Thought I would share a couple pictures of a recent questionable find. I know, it looks like a piece of shrapnel. And it might just be. I found it 6 down using my Gold Bug II. I was detecting an area within a 40 acre parcel up in the pinions. It intrigued me so I put it in my pouch and brought it home to check out. I did a couple nickel tests on it and both times it produced a strawberry red color on the swab that stayed longer than 5 minutes. It doesn't seem to become a magnet it weighs 12.4 g and after doing a bulk density weighing I came up with a 7.75g/cc I tried etching a small area on it but did not see a pattern emerge. My test area might have been too small. The piece shows many small cracks on it. It has obviously been subjected to some pretty good forces to break it leaving such a small jagged piece. The shape isn't what I would consider typical for an iron; and the little bugger smells strongly like metal when handled. I soaked it in CLR for about 3 days so I could see what the surface features looked like It's interesting, especially under magnification. Makes me wish I knew what it is. Oh well, another one for the possibles pile.

Re: [meteorite-list] I know what it looks like. . .
Hi David, other interested list members, The Lone Ranger could have been up there on that mountainside in those woods, I don't know. If he had been, he would have probably had iron on his hip, which sometimes while up in the thick timber by myself, I wished I'd had on me. Pepper spray just doesn't seem to be the right thing to have somehow. A 357 or a 32 Winchester Special would be more comforting, if you know what I mean. And then too, what good is a prospector's pick with a 16 handle. Probably not much. I doubt if a mountain lion would care if his prey was carrying a 16 prospector's pick or, for that matter, if he was swinging a metal detector, eh? Anyway, by my reference to performing bulk density testing, I meant I was following the steps mentioned in the Field Guide to Meteors and Meteorites by O. Richard Norton and Lawrence A Chitwood. Page 254. Step 1, weigh the specimen. Step 2, zero out the scale with a container of water sitting on it. Step 3, weigh while specimen is suspended in the water. Then divide the specimen weight by the suspended specimen weight to get the g/cc. Once I had done this, I compared the result with the chart in the Guide on page 253 just to be sure I was somewhat correct in my testing. Looked to me that the 7.75g/cc was right in the ballpark for an iron but then I have to say that I don't know fully what man-made iron average bulk density weight is so it could be man-made just the same. From what I can read on the net, man-made iron bulk density average should be comparable to an iron meteorite bulk density average. My scale is a Palmscale 8, not that that matters a whole lot but I believe it is a pretty accurate little bugger. All the best, Mike in CO On Oct 2, 2010, at 4:18 PM, David Gunning wrote: Hi Mike, Odd looking specimen you got there. If it's got a specific gravity of 7.75 it falls within the range of being a piece of iron (7.3 - 7.8). I am not sure what you mean when you say after doing a bulk density weighing and coming-up with 7.5g/cc. According to Professor Randy L. Kootev, an internet expert on these kinds of measurements: In order to measure density, it is necessary to measure the volume of a rock. That's hard to do accurately. In any event, from the pictures you posted it reminds me of some sort of bullet mold. But what I don't understand is the nickel test reaction. But, then, there are many things I don't fully understand. Maybe King-o-sabi (the Lone Ranger) was casting silver bullets with it. Some chemical tests for silver can turn strongly red colored, and if there was a residue of Silver, who knows? Hi Ho Silver, Up, Up and Awa!

Re: [meteorite-list] grey fusion crust on a stony?
Hi Eric, Pat, Martin, Steve D, Jason and any other interested parties on the Met-List I managed to take a half-bad picture of the little grey stone in my earlier post. My excuses for such a bad photo are that it is tiny, so hard to photograph even through the scope. Also lighting is by the ring light on my scope so the true color is not there. Close though. One thing I was hoping to show with this picture is the cracks all over it. Inside appears to be somewhat of a root beer color outside is ash grey. Not sure if it is a meteorite but it is interesting to look at. I found it with my magnet rake. The little stone is strongly attracted to a magnet. It has little silvery specks showing on the outside. The whole stone looks like it would crumble if handled but actually it is not that soft. Anyway, just thought you might want to see what I was so curious about. Thanks everyone for the help on the grey crust question.

Re: [meteorite-list] Classification of Chondrites
Don't pay much attention to my guess but I say H5. Few chondrules, evenly spread concentration of metal flakes. If I read the chart provided in the Field Guide to Meteors and Meteorites correctly, bulk density for H5 should be about 3.4. You could check that. I have a question for you though...Can you see the metal flakes through the crust? I found a small one that I think is similar. I can se the flakes showing through on the outside that's why I'm asking. Mike in CO On Aug 17, 2010, at 4:29 PM, David Pensenstadler wrote: What timing.

Re: [meteorite-list] Perseids.
We had clear skies here in southwest CO. I was out watching starting at about 9 PM. Saw an eyepopper of a meteor at about 9:15. Long tail, orange tint to it. I'm certainly no expert on meteors but sure looked to me like this one made it into dark flight. I've seen a daytime fireball and watched the big one that went over to California a while back at night but the first one I saw last night was by far more spectacular to see. Last night, I also watched several that were multiple pieces of 3 or more traveling side by side. They went pretty much directly overhead going north to south. For the last few years we had clouds during the Persieds. Nice to finally get to watch some of the shower.

[meteorite-list] bulk density testing
Hi List, I want to be sure that I'm fully understanding the correct method to perform bulk density tests. I'm attempting to follow the steps in the Field Guide to Meteors and Meteorites. If someone would check me on this I would greatly appreciate it. Here is what I have been doing...I'm using a Palmscale 8.0. I'm weighing the specimen on the gram scale, then placing my little vial of water on there and after zeroing, I place the suspended specimen down in the water being sure not to touch the bottom. Using those two figures, I have been dividing the specimen's weight by the weight of the specimen suspended in the water. My most recent test gave me a 1.3g weight on the specimen by itself. Then a suspended weight of . 3. If I figured it correctly with my division, that gives me a 4.33 bulk density. The little specimen was not porous. Using this same procedure, I tested a different specimen, not related, and came up with a 4.555 result for it. Comparing those weights to meteorite densities in the chart in the Field Guide, the results indicate stony irons. It seems simple enough. Am I close?

Hi Chis, You might see if you captured video of one that took place at 9:15 or thereabouts tonight. I watched it go from north to south or southeast a bit. It was west of Montrose. It was a spectacular thing to see with a long trail behind it. I'd call it a small fireball. I would be interested in knowing if you caught it on your cameras.

[meteorite-list] Found this yesterday
Hi List, I found this strange stone yesterday metal detecting. It is weird in that it sounds off on my Gold Bug but does not sound like a hot rock. More like a small nugget. Going by feel only, gross density is less than 3. Seems light for its size. It's very friable in some areas, other areas on it look like melted glass covers them Slight but definite magnetic attraction Color in photos is pretty close to actual. A big portion of the stone has an orange color, other areas on edges is more tan-grey. There are orange inclusions here and there throughout what I can see. Orange material seems to have a different melt point than other material. Other than that, it looks to have some white material under some of the clear glassy exterior.

To my eye, it has some of the same surface features as one might expect to find on a small iron meteorite. It sure threw me, I first thought it might be an iron meteorite, at least until I got it cleaned up and saw the remanent threads. Mike in CO ps, For fun... What do you see in this picture, a honeycomb with holes or bumps? Look at it for a bit, then scroll down so it is out of sight and then scroll back up to see it again.

Re: [meteorite-list] Meteorite Question
Hi Pete, List, Good question. I don't have your answer but have been pondering on the main mass thing myself. When I see the words main mass mentioned, I conjure up a mental image of the biggest piece of meteorite recovered from the strewn field of a known fall. Otherwise, if you simply find a piece of meteorite, whether whole individual or not, you quite possibly will never know if it is the biggest piece from that fall or not. I hope that is close to being correct. Mike in CO On Nov 9, 2009, at 8:37 PM, Pete Shugar wrote: What is the smallest Main Mass and as a bonus question, who has it? I hold a NWA 1953 @ 11.73 gm.

[meteorite-list] sharing some pictures of little [suspect] irons
Hi List, Thought some of you might like to see some more pictures of my little suspect irons that I have been trying to get cleaned up. It is a slow process. Here is a few of them. This little guy has what appears to be flow lines running down to the point, wouldn't you say? It took some long soaks in naval jelly to get it looking this clean. It's amazing what you can find when you get the crud off of them. http://i127.photobucket.com/albums/p124/mmurray_02/IMG_1118.jpg The next two pictures are of the same piece.

It is a shell of iron filled with what appears to be chondritic material. It reminds me of a three-minute egg with the top taken off. I believe I have at least three pieces like this. http://i127.photobucket.com/albums/p124/mmurray_02/IMG_1114.jpg I like how this one has a little finger on the one side, and how as it cooled it kept what looks like flowing metal. http://i127.photobucket.com/albums/p124/mmurray_02/IMG_1115.jpg Here are the two I have been trying to get the calcium cover off of.

[meteorite-list] naval jelly soak gone wrong
Hi All, I have a question if I might please. I had put some small (suspect) irons in naval jelly then neutralized it with baking soda and then removed them and rinsed them. Then I had wire brushed them with a small hand held brush. Several pieces came clean and chrome looking for the most but they still had a couple places where the buildup of corrosion was still there. So I put them back in with some other pieces to soak in the naval jelly some more. When I removed them the second time, I found all three pieces that I had wire brushed once before were now heavily coated all over again. The coating was blue and grey crystals looking. I tried wire brushing that off only to find that now the brushing leaves them looking like they are coated with oxide again. It is like the naval jelly soak worked in reverse. The other pieces that I had thrown in the navel jelly soak with them did not get wire brushed previously and they came out clean. So I learned don't soak them twice but not sure why exactly. Now I'm wondering if someone can tell me what will take the new coating off? Anyone have a similar experience?

HI List, This little suspect iron passes my home do-it-yourselfer tests. If it is a meteorite, I'd say it's a bit unusual in that it is very thin, maybe 2 or 3 mm at the thickest. Course though, it is also very small. field of view for this picture through the scope is about 10 mm. Thought you might like to see the picture.

Along that same idea, for a typical chondritic meteoroid, what is the minimum size that you might expect to make it through the atmosphere and land as a meteorite?

Re: [meteorite-list] Flow lines on the INSIDE! Not. (cleaning irons follow-up)
Hi All, I put my little suspect iron in a solution of water and calcium carbonate. I actually wrapped it loosely with tinfoil and sat that down in the mixture. I got out my trusty battery charger and connected the red lead to a sacrificial piece of junk strap metal and sat that down along one side of the plastic bowl. I connected the black lead to the tinfoil. Actually clamping it against the side of the bowl same as I did the piece of strap on the other side of the bowl. Anyway, I poured in a couple teaspoons cleanser and swished it around with a plastic spoon so it was dissolved good. Plugged in the charger and watched as a steady stream of bubbles headed from the tinfoil towards the sacrificial anode strap. After about two hours of cooking, I can now see what I have. A really sculptured, bright chrome something that is as hard or harder than tool steel (don't ask how I know that last bit) and shaped like a stretched out version of Willamette. I did a nickel test and think now with all I see that it might need to go to someone to get checked further if I want to know for sure. Anyway, the process worked better than I was expecting. Doesn't seem to be dangerous to do. I put the charger on 12V, 6 amp scale. I left the solution outside when it was cooking. I treated my specimen to a bath in penetrating oil when I had finished cleaning it. One more interesting tidbit, looks like after the red rust was removed, left on the suspect rock is a very thin black coating in quite a few places, mostly in the low spots. If that is magnetite then I answered my own question, no, the process doesn't remove the oxide, only the red rust. My little experiment worked well enough for my purposes, but hopefully no one with a stone of any value will follow my lead. I would hate to think I inspired someone to ruin a valuable specimen.

Perhaps the best example of such weathering can be seen on irons from Gibeon. I unfortunately don't have a copy of Buchwald here, but if anyone does have access to the second volume, if they could flip through the Gibeon section, they would find a photograph of a beautiful mass of Gibeon (I forget the name of the mass) on display in a museum in Germany. It displays beautiful fusion crust and smooth-edged, shallow regmaglypts - it looks as fresh as many Sikhotes on the market today. Compare it to many of the larger Gibeons on ebay today and you'll see little-to-no resemblance. If anyone out there can scan a picture of said page, I'd be much obliged. It really is a good example. There are, however, a few common irons which I would never expect to have fusion crust: Canyon Diablo, Toluca, Odessa, and Nantan, to name a few. I've seen hundreds, if not thousands of examples of each, and I have never seen a single one of any of them that came close to being fresh enough to retain a trace of fusion crust. Nantan is one of the most corroded and least stable iron meteorites I have ever known, though Dronino's turning out to be about as bad. People need to learn more in order to clear up the misconception that all meteorites show signs of a hot, violent entry through the atmosphere; I see NWA's on ebay all the time that are nothing but old weathered fragments coated with desert varnish. Check out this seller: http://myworld.ebay.com/eegooblago/ Almost all of his stones are covered in a 'glossy fusion crust.' Oh wait - those are just desert varnished fragments that have been weathered to hell. Most of the melt features the seller notes are due to sandblasting and corrosion, and s/he goes so far as to say that the cracks in his stones formed when they hit the ground! Anyone remotely familiar with meteorites and weathering processes knows that over thousands of years, meteorites fracture and break apart, in a manner completely unrelated to their having

Re: [meteorite-list] Nickel tests
I'm calling it native iron because that is what the tests showed. It is possible and the person making the analysis also stated that it could be meteoritic material. I don't know. It is some some pieces of metal from about 3/16 to 3/4 at the widest. The pieces are strongly susceptible to a magnets attraction, more so even than magnetite . It is very hard and chrome looking metal. It just doesn't look like an iron meteorite, at least not to me.Close though. So anyway, that is what it is. No sign of nickel though. All of the pieces were found here in southwest Colorado. If terrestrial, it may be that I can find it here because we have some old calderas in this area. Just a guess.

Most stall holder have travelled hundreds of miles to get here, so for them it will be a financial disaster if it doesn't calm down soon. Storms are quite common this time of the year but they normally don't carry dust of this magnitude. The dust was originally moved earlier this year from inner eastern Australia to the west when unusual heavy downpours in north-eastern Australia created countless little 'rivers' and filled up the normally dry salt lake called Lake Eyre in the north of South Australia. Something like this happens only once in every decade or even less and it creates a wonderful show of nature where the wildlife flourishes for a few months until the lake dries up again. And this is happening now and millions of fish and thousand of pelicans and many more other animals are dying. A paradise is turning into hell right now and since hundreds of thousand tons of fine dust travelled with the water to this region, it is changing now from mud to dust again and those normally harmless yearly storms pick up this fine material and carry it from west to east covering a large part of Australia. Unfortunately, Broken Hill is the first major city that gets hit by these storms and by the time they reach the east coast with cities like Sydney and Brisbane, the number of particles per cm³ is much less. Still, people with health problems will be badly affected there too. Anyway, nothing can stop me from going to that show.

In addition I also tried to magnetize a couple of prospects that I have and they too did not become magnetized and yet other pieces of found metal that's clearly not meteorite material did become magnetized. You are quite the genius and thank you so very much for sharing. Thank you again and again. Carl PS they claim if results can be replicated that theory becomes fact? I hope this is now a fact because a few found irons might just get added to the it's a keeper for more testing pile. -- Carl or Debbie Esparza Meteoritemax Michael Murray mmur...@montrose.net wrote: For what they are worth, here are a couple suggestions... If you place the suspect iron on a strong magnet, then remove the magnet, the suspect iron should not retain magnetism (if it's a meteorite) but should to some extent if man-made iron. Kind of like magnetizing the tip of a screwdriver. You can test the once magnetized suspect iron to see if it will attract fine particles of magnetite, Not very scientific I know but it is a good indicator I think. Another thing you can try if the suspect iron is not very big is to place it on a strong magnet (super magnet if you have one) and if the iron piece wants to orient itself up on one of it's ends on the magnet, I would rule out meteorite. If your suspect iron is large, you'd probably have to remove a small piece of it to do this test. If the small piece lays down on any of it's sides on the magnet and doesn't want to orient itself, I'd put it in my 'it's a keeper for more testing' pile. I bought a couple nickel test kits. I have tried to be as careful as possible to do a clean uncontaminated test on several suspect irons. After doing quite a few, I still don't trust the results. It's not that I don't get positives, I do. It's that I've learned not trust the positive tests all that much. If I find a big enough suspect iron someday with enough other indicators that it could be a meteorite then I will let a lab do the testing so I can rest assured the results are going to be more trustworthy than mine. Meanwhile, my 'it's a keeper for more testing' pile continues to grow.

So I guess the only way to confirm slag (if you can't do it visually) is to cut it open and if there are holes / bubbles then it is slag. Or if the slice doesn't look like a meteorite slice it is slag. For the record, I am personally looking for west like fusion crusted stones and this is what I am training people to look for. At the same time when I get reports about weird rocks I have to follow up and take a look. Not all slag looks the same, there are a lot of different types. I'm getting pretty good at identifying / ruling things out, but the nickel test threw me for a loop. __ http://www.meteoritecentral.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list __ http://www.meteoritecentral.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list __ http://www.meteoritecentral.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
Re: [meteorite-list] Strange Rock Reports Decrustified Meteorites
decrustification I like that word! Mike in CO On Sep 17, 2009, at 2:11 PM, JoshuaTreeMuseum wrote: Listerians, I get the feeling that some folks feel that fusion crusts are indestructible, or are unfamiliar with crustless meteorites. These stones are from 5 different NWA falls. The stone that looks remarkably similar to Mike Hankey's slag can be seen next to a crusted piece from the same fall. Of course the Hankey Stone meteorites would have fresh black crust. If Mike's slag had come from NWA instead of PA, I would be inclined to think it's a meteorite. If you put these in the bright sun, the metal flecks and chondrules are plainly visible. As to how or why these stones were involved in a process of decrustification if beyond me. Maybe it was an extra thin crust. Something about the silicate materials? Maybe the crust was eaten up by tiny black holes, maybe the spawn of Cygnus X1? http://i190.photobucket.com/albums/z126/tboswell/a.jpg?t=1253217247 http://i190.photobucket.com/albums/z126/tboswell/b.jpg?t=1253217282 http://i190.photobucket.com/albums/z126/tboswell/c.jpg?t=1253217307 http://i190.photobucket.com/albums/z126/tboswell/d.jpg?t=1253217334 http://i190.photobucket.com/albums/z126/tboswell/e.jpg?t=1253217361 Phil Whitmer __ http://www.meteoritecentral.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list __ http://www.meteoritecentral.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
[meteorite-list] searching for the correct terminology
You will probably think I am a bit off the latch with this question but here goes anyway... In the world of meteorite terminology, is there a term or word which describes the loss of fusion crust (by forces of nature) from stony meteorites. 'Spalling' possibly? The loss of crust, part or all, seems to be a rather common occurrence especially for some of the more friable stonys. With the crust gone, the stone is 'denuded'?

Re: [meteorite-list] OT: Searching for the correct terminology
From what I can observe on some small specimens, it is more than just the removal of fusion crust that is involved. As the crust is broken or chipped off, due to whatever cause, there is a certain, albeit small amount, of the matrix removed also, leaving the newly exposed surface very rough. Pitted if you like. The shape of the stone is not changed all that much of course, and without magnification, one might not see what the remaining surface is like. Weathering or whatever the cause, it is a fantastic thing to see the exposed matrix in its rawest appearance. Fusion crust has its own special appeal and I don't mean to be taking anything away from crusted stones with my thoughts on this. Mike in CO On Sep 11, 2009, at 6:04 PM, Sterling K.

As England is without any doubt the most invaded country in history (with the possible exception of parts of the Middle East), its language contains remnants and relics of words from over 60 languages. Some of them are more or less inexplicable -- English has a few Sumerian words. No one has any idea how that happened. Calculating how much of English comes from what language is a messy business and estimates vary widely. The French always comes out on top because they were the most recent invaders! There are delicate issues here. Do you count Scots words as a dialect of English? Think twice before you open your mouth!

Re: [meteorite-list] Fireball: Huge Explosion Over Ireland
Eric, and List, Mr. Moore was quoted as saying: If it's brighter than the full moon then there's a chance that part of it survived and landed, he said. I'm not sold on the idea that size(read that same as brightness in this report) is the most relative factor in survival. I tend to think speed and angle of entry play the bigger role in how fast a stone burns up. Wouldn't a small meteor have the same chance, as a big meteor given the right speed and angle of entry? A small, say 1 meteor, may only burn for about 1/4 to 1/2 second versus a football size may burn for 5 seconds or longer.
