Yes, i see a lot of flight-marked meteorites that wouldn't qualify as truly oriented. Round doesn't mean oriented either and I see that misrepresentation a lot.

Re: [meteorite-list] sharp protrusion from an iron meteorite
Hi Jason, you're often too hasty (and somewhat egocentric) to discuss a simple argumentation soberly. I say nothing else than that the advertisings of your material, in particular of your unclassified alleged NWA 7034-pairing and the unclassified supposed NWA 2975 pairings, are misleading or at least apt to lead to misunderstandings for the collectors. In that sense, that they raise the impression, that your material was decided by a professional meteorite scientist (in the meaning of the CoE) to be officially paired to the numbers/meteorites NWA 2975 and NWA 7034 and not only grouped to them by your personal inspection/opinion. Hence a case of the so-called self-pairing. All I suggested to you, was to give the collectors/buyers clear and sufficient information, that they can make their decisions, whether they like to buy or not. Hence to make it clear, that based on your own and personal observations, those samples you are offering shall be paired to the numbers you refer to. Why shall this be so difficult? Here you freely stated, that it was you, who scrutinized each sample and that you decided them to belong to NWA 7034, because you used a microscope and because you once had a few grams of Jay Piateks original 7034 inspected. And in the NWA 2975-case, because those stones would be easily to recognize. So just write it there. And leave it to the people, if that kind of analysis is sufficient for them. (I for my own for instance think, that I haven't that gift and experience to be able to decide or to identify, whether such tiny microfragments are a certain meteorite, especially not, when it's a breccia and I have only some photos, a written description and the remembrance of minor quantities I took once a short looked at, at hand). And everything else, your personal views, whether it's useful to let every planetary get numbered and to give the required share to the classifiers...is simply not of interest, as long as you have signed the CoE of the IMCA to obey the formal requirements given there, to present your material for sale and trade. As my view could be wrong too, I invited you - that we write both together a formal complaint, each of us telling our opinion, and let just that organization independently decide, whether your presentation of the material fulfills the requirements of that organization or not. For me it's necessary that we do that together, cause if I would ask at IMCA alone, others could misunderstand that as a hostile act from me towards you. And I think, that's an idea, which meets also your sportsmanship. Again, in my opinion and as it happened also in reality with the case of the interested collector asking in the German forum, your description and the use of the numbers can be misleading. Little example, Here on the list you advertized your material like this: Title, I quote completely: AD - Black Beauty http://www.meteorite-list-archives.com/2013/feb/0164.html Black Beauty is the name attributed and used before for NWA 7034. And the text of the ad reads as follows: Hello All, I just finished the page for some fragments of the unique water and soil-bearing Martian regolith breccia paired with NWA 7034 and a few other stones. Please see our website for available specimens. http://www.fallsandfinds.com/page88.php Thanks! Jason There is standing definitely paired with no other constraints, so that the reader concludes, it has to be a pairing officially ascertained by a meteorite scientist. Furthermore, the detailed disclosure of the nature of the material, (the unique water and soilbreccia), so much grammar I still know, relates to the some fragments but not to NWA 7034, so that the reader must have the impression, those fragments you offer were properly analyzed by a scientist, who found out, that they are just such a regolith breccia like NWA 7034. Or to say it more simple: After I read your explanations of the recent posts, I have to say, when this AD was no self-pairing, then I really don't know, what the term self-pairing is about. Let's go on. When I go on your sales page, http://www.fallsandfinds.com/sales.php I read in your inventory: ' The Black Beauty Unique Martian Meteorite ' Hence again the name used for NWA 7034. And I read: 'NWA 2975, Martian' (the same I read in the menu side bar, when I switch to the other pages). Well... do I go on the 2975-page, I get the bold title: NWA 2975, Shergottite (Mars) And the first sentence: These small, complete martian stones are paired with NWA 2975 as well as its several pairings. Can't help, if I read Porsche I wouldn't expect to find a Volkswagen Beetle - although I know, that both are cars. You know, Jason, most sellers of such unclassified stuff would use expressions similar like: NWA likely paired to... or possible Martian... ect. Hopefully now you understood, what my concern is. and think this is BS because you're attacking me for things I've said to you in the past.

Re: [meteorite-list] sharp protrusion from an iron meteorite
Jason Stated: I both disagree with you two -- and think this is BS because you're attacking me for things I've said to you in the past. My response: Jason, please leave me out of your immature rants. I certainly have had every planetary pairing examined by a competent scientists and followed proper procedure to get official numbers for entire batches. I stayed away from Tissint other than a personal piece for my own collection. I never offered any because it was tainted by inexperienced dealers from the moment it was found. I tend to stay away from planetary pieces with mass pairings and was not involved with Tissint knowing that emotions, not experience would dictate the market. In the case of NWA 2975 that you refer to, I had around 38 individuals examined by a real scientist, donated the required 20%, paid lab fees and made every stone official under the NWA 4880 nomenclature. Each and every piece was examined by Dr. Irving, a well known real planetary scientist, not a self-proclaimed one. It has been my experience that people that focus too much on the faults of others are usually guilty of what they are accusing others of. Now, please do not try to checker my reputation again. Nobody likes a ta-tel-tale or a snitch, especially when his accusations are unfounded and untrue.

Re: [meteorite-list] Membrane boxes go boom?
Hi all! I have never recommended the membrane boxes for storage...and in particular long term storage and fall recovery storage on fresh samples. What are you guys using them fordisplay sort of thing? My choice of storage: 1. Pure glass container - jar with glass lid with specimen above a dissicate bag or two. 2. Teflon bags - kinda pricey but good stuff for long term storage and movement of samples, imho 3. None, in open air. (I live in the desert) 4. Gem Jars None of these have ever let me down. Last period of time I quit using a membrane box was shortly after looking at Robert Wards Sutter Mill find that was in a membrane box. As I looked at it, I noticed a fracture and I think both of us sh** our pants at that point in time as RW did not see that prior. My suggestion was to loose the membrane box. I am not saying the box caused it, but the rock did not need anymore pressure on it! What an awesome rock it was! The only membrane box I have left in use has a small Allende in it that I purchased from Anne. I just don't use them...not that I have any sort of huge collectionjust the opposite really! Cheers!

Re: [meteorite-list] Membrane boxes go boom?
Sorry to hear about your membranebox Sean. But Ghubara is a bleeder and I never put a ruster or bleeder in a membranebox because they will stain the polyurethane membranes permanently (on a good note, Ron H. used to replace them for me, or broken latches before he passed). Also, if you live in a highly humid environment like I do, then you don't want to be using membrane boxes for certain kinds of specimens because they will trap the humidity inside. I typically mount and store specimens I keep in membrane boxes in my institute office, which is kept in climate controlled AC 24 hours a day. Tracy, I've never experienced a membrane getting cloudy. But as I mentioned before, all membrane boxes are kept in an air conditioned office. I have membrane boxes over five years old that are in the same condition as new ones, both enclosing specimens of all kinds and never used. Other than the aforementioned issues, membrane boxes are a great solution to storage, protection and display of specimens. gary On Mar 5, 2013, at 5:55 AM, Sean T.

[meteorite-list] More Curiosity Computer Troubleshooting on Tap
http://www.spaceflightnow.com/mars/msl/130304computer/ More Curiosity computer troubleshooting on tap BY WILLIAM HARWOOD STORY WRITTEN FOR CBS NEWS SPACE PLACE USED WITH PERMISSION March 4, 2013 Work to carry out what amounts to an electronic brain transplant aboard the Curiosity Mars rover -- a complex sequence of steps to switch operations to a backup flight computer -- is continuing this week amid ongoing analysis to figure out how to resolve memory corruption discovered last week in the rover's active computer. The memory glitch interrupted science operations, forcing flight controllers to put the craft in a low-activity safe mode while the computer switch was implemented. Richard Cook, the Mars Science Laboratory project manager at the Jet Propulsion Laboratory in Pasadena, Calif., told CBS News Monday the computer swap was going well and that limited science operations should resume shortly. We spent the weekend kind of getting back, not totally to regular operations, but at least out of the immediate safe mode kind of a thing, he said. We got it out of safe mode, got back to using the high-gain antenna, so we're well along the way to restoring things. The problem cropped up last Wednesday when Curiosity failed to send back science data as expected and then failed to put itself to sleep during scheduled downtime. Reviewing telemetry, engineers discovered data corruption in the solid-state memory used by the rover's active flight computer. Curiosity is equipped with two redundant computer systems, known as side A and side B. Either one is capable of carrying out the rover's mission and only one operates at a time with the other on standby as a backup. The B-side computer was checked out during the cruise from Earth to Mars while the A-side computer has been running operations since before landing last August. Cook said the switchover to side B is a complex procedure and that engineers are taking their time to make absolutely sure the process is carried out correctly. We have some more work to do to upload configuration files and parameters, things like that, so it's going to be another few days or so to kind of get things totally recovered, he said. But basically, it's going well. Once the B-side computer is fully up and running, limited science operations should resume. But Cook said the engineering team wants to have a better idea of what went wrong with the A-side memory before going full throttle on the B-side computer. Engineers suspect the memory glitch might have been caused by space radiation, a single-event upset in which an energetic particle made it through radiation-hardened components and changed the state of one or more memory addresses. As luck would have it, the corruption was found in the memory's directory, which tracks where data is stored. If that theory is correct, booting the A-side computer and its software would be expected to re-write the memory blocks, presumably flushing the corrupted data. In that case, assuming no other problems, the A-side computer would be deemed healthy and cleared to serve as backup to the B-side computer. But before attempting a full re-boot, Cook said, engineers plan to power-up the A-side machine Wednesday, without loading software, to check the status of the non-volatile memory. The first thing you can do is just turn it on without software running and just treat it like it's an extended memory bank, he said. That's actually what we're going to do first, we're just going to read the memory. If it comes back saying it's got a bit error, then that means it's still corrupted. Because the memory retains data when it is powered down, engineers expect the corruption will still be present when they power the system back up. The real question is whether data can be successfully stored in the affected locations. If you then turned around and wrote to it, and it said, hey, I still can't write to this memory cell without getting an error, then it would tell you there's something more systemic going on, or more permanent, Cook said. It's a bit of a catch-22 for the computer experts at JPL, he added. Letting the computer's software boot up and write data to the suspect memory locations would destroy evidence that might help pin down what went wrong in the first place. So the first thing we're going to do is just bring it up, read the memory, dump memory from the areas where we think we had a problem and take a look at that and then decide what to do next, whether or not to write it, Cook said. If it looks like it's all better, we may just bring software up and then software will essentially do the same thing, but for all the memory at once. If the memory problem cannot be corrected, programmers could attempt to bypass the corrupted locations with a software patch. There are multiple banks of memory, it's not a single monolithic thing, Cook said. So if you had an uncorrectable error in one place, then you could effectively map it out, you

Dear Sellers on the list, I have been looking to purchase a number of different meteorites, so I have been going to the webpage links under some of your seller messages. What I find on some pages are a bunch of items that appear to still be for sale, but when I go to the meteorite linked page, it says SOLD. I ask... if you have it listed on one page for sale, then when you go to the item page it is sold, and you have posted it that way... why keep it on there? It makes it more difficult to shop around, and I will probably not shop on that site any further. I see something that appears to be for sale, and I think I might want it... only to find out it sold, over and over on that site.

Re: [meteorite-list] Frustrated over some sellers pages
Hi Mike, That is one of my peeves also. But Mike Farmer raises a valid point - it can be difficult to maintain a website that has hundreds or thousands of specimens. This is especially true if one has a day-job, such as flying all over the world hunting meteorites. I get that. But, there are a few dealer sites out there that have not been updated in months or years. In those cases, I'll email the seller to see what is available. As for myself, I generally have around 300-350 items listed on my website at any given time. I used a hosted eCommerce store and the monthly fee is based (in part) on the number of items a seller has listed. If I go over 500 items, I get bumped into the next highest tier of pricing. So I keep my website offerings trimmed down on a regular basis to ensure I don't go over the limit. Once an item sells, I will leave the listing up just long enough for the buyer to receive the specimen and compare it to the listing. I think it looks suspicious if a seller immediately deletes an item right after it is sold. After about a week (following shipment) for a domestic order, I will delete the item. I wait about 10-14 days to delete an item purchased by an international buyer. There are a couple of exceptions - I have a high turnover rate for micromount specimens. I regularly run out of some, but always end up buying more and restocking. So, if I run out of something relatively common (like NWA 869), I will leave the listing there until I get some more - rather than delete the listing and then completely re-write it when more material comes in. I had considered having a Sold Archive of previous specimens, but I would have quickly gone over the 500 item limit long ago. I do keep a folder on my PC that has all prior photos and most prior descriptions for past items, so if a buyer (or myself) needs to reference a given listing for some reason, I can go dig it out of my hard-drive.

Re: [meteorite-list] Frustrated over some sellers pages
Hi Mike and All, When I built my web site and announced it in December one of my goals was to try and address this issue in an easy and sensible manner for all concerned. It is quite a challenge even to update a sold item the minute it is paid for so no one else asks to purchase the item that had just been sold. Whenever I offer something new or have a sale I try to make sure I am at my computer for a few days in order to fill orders and mark the items sold or take them from the site. I have a database switch where I can show sold items or make them hidden. Typically I like to show what has sold in the beginning of something new I offer so everyone, buyers or non-buyers, can see what the meteorite looks like. In the meantime, go shopping at Nature's Vault and let me know what you think: www.NaturesVault.net (Online Catalog Reference Site) Best Regards, Greg Greg Hupé The Hupé Collection gmh...@centurylink.net www.NaturesVault.net (Online Catalog Reference Site) www.LunarRock.com (Online Planetary Meteorite Site) NaturesVault (Facebook, Pinterest eBay) http://www.facebook.com/NaturesVault http://pinterest.com/NaturesVault IMCA 3163 Click here for my current eBay auctions: http://search.ebay.com/_W0QQsassZnaturesvault -Original Message- From: SatWatch.org Sent: Tuesday, March 05, 2013 11:33 AM To: meteorite-list@meteoritecentral.com Subject: [meteorite-list] Frustrated over some sellers pages Dear Sellers on the list, I have been looking to purchase a number of different meteorites, so I have been going to the webpage links under some of your seller messages.

Re: [meteorite-list] Frustrated over some sellers pages
Folks, IMHO, I like seeing other specimens on the same page that are already sold... though I agree that web page design can eliminate some confusion by having a section for available and a section for sold. Many times when I am searching for specimens and history on the Web - it's great to see other examples of the same material... even if it is already sold. As for the issue of maintenance - yes - it can be troublesome. But work with your Webmasters. There are multiple ways to handle quick updates for material that is no longer available, including having dynamic pages that reference a SOLD or ARCHIVE flag for each specimen. Then, updates can be rapid and painless if you take the extra up-front time on your site design. Another thing for folks to consider is provenance. I can't count the number of times I've researched a specimen I acquired that has passed through a few collections / dealers. It's nice to see your exact specimen on an old site page that is still listed. I usually screen-capture the page and print out a page to store with the documentation for the specimen. In a few cases, I've found provenance information that I did not know existed. Always a bonus!

Re: [meteorite-list] Frustrated over some sellers pages
Aloha Michael, I will try to answer your question. Here are my reasons for keeping specimens up on a webpage after they have been sold: 1. The webpage documents a particular meteorite that I have acquired/analyzed/classified, along with its subsequent cuttings or components that were offered to the collecting/science communities. Marking a specimen as sold and keeping it on the webpage serves as a record for all of the pieces I have sold. I have had numerous inquiries from clients who had questions or issues with their purchased pieces and without the images and information documented on the webpage, it would be difficult or impossible to recreate. 2. Although I am not an active hunter like Michael Farmer, I do have a day job in addition to running a business. I don't have time to update all of my webpages, as I typically sell 60-100 meteorites a week. I also acquire new meteorites on a semi-regular basis and must create new pages for them. 3. The webpage documents market value or pricing for a particular specimen. It is interesting to see how prices have remained fairly stable despite the steady rise in pricing over the years. By not keeping the sold items and their associated prices on the webpage, there is no public record of these specimens (of course I have business records). 4. Showing the sold items along with the available ones gives the website peruser the ability to gauge the popularity of a meteorite. Visiting a website over a period of 24 hours after a specimen has been offered can show a great deal of activity in sales. And many meteorites I have offered have sold out within 24 hours. 5. I do not compare meteorites with clothes. I do not buy clothes in the same manner as I buy meteorites, and do not expect others to do so either. I don't care whether a particular size or color of a garment is available or not. I do care if a particular inclusion or chondrule is present in one slice or another. A prospective buyer would not be able to do this if I took down a specimen immediately after selling it. 6. Provenance. Maintaining a webpage with its sold items is a documentation of specimen provenance. Of course each item sold comes with a Certificate of Authenticity (CoA) from my business, but the images on the webpage are invaluable for authenticating a particular slice or piece in addition to, or absence of said CoA. 7. For Mike at Satwatch.org, all specimens offered are available or marked SOLD on the same page. It is not an inconvenience to the prospective buyer because he is not redirected to another page. I am not going to create another archive page because that is more work, and would be more confusing to navigate than the system I currently use. I hope I have explained appropriately and clearly, the reasons for maintaining sold specimens alongside available ones on my webpages. I have done so not to make your lives more complicated, but to offer documentation of all meteorites sold that I have had analyzed and classified. Some dealers don't do that, but rather than think I that I am making it more difficult for buyers, I like to think that I am offering more value added information and provenance to buyers and prospective buyers. gary On Mar 5, 2013, at 6:41 AM, Michael Mulgrew mikest...@gmail.com wrote: Mike, I asked the same question in spring of 2011, please refer to that thread for some discussion: http://www.meteorite-list-archives.com/2011/apr/0507.html -Michael in so.

Re: [meteorite-list] Membrane boxes go boom?
A completely unofficial count: Of the 12 membrane boxes I have, about half of them are going cloudy. All but one are meteorites; the other is a Louisiana opal (sandstone matrix). Fortunately, none of the professional displays (enclosed labels) or specks it would be problematic to rebox (Martians) have decayed yet, although that may be coming. I mainly use the membrane boxes when I have a specimen whose aesthetics are enhanced by being able to see (through) both sides, or if it came that way. If you use membrane boxes to create those nifty display boxes with elaborate inside labels, you may want to take their apparent shelf life into consideration. My meteorites are not in a climate controlled area, although once a specimen goes in a gem jar or box, it generally stays there and has limited exposure to the outside air. Best!

Sorry to hear about your membranebox Sean. But Ghubara is a bleeder and I never put a ruster or bleeder in a membranebox because they will stain the polyurethane membranes permanently (on a good note, Ron H. used to replace them for me, or broken latches before he passed). Also, if you live in a highly humid environment like I do, then you don't want to be using membrane boxes for certain kinds of specimens because they will trap the humidity inside. I typically mount and store specimens I keep in membrane boxes in my institute office, which is kept in climate controlled AC 24 hours a day. Tracy, I've never experienced a membrane getting cloudy. But as I mentioned before, all membrane boxes are kept in an air conditioned office.

It's not attracted to a magnet. I'll note, there are pictures of the rock, from earlier, in which not only is the lighting a little better, but between the two photo-sessions, I had displayed the stone on the surface of a stereo loudspeaker, apparently therefore causing some of the globular portions of the coating to turn white, and to dust... In the crevices, and next to various lips, accumulated (somehow), black-coloured material still remains (only a small portion of it was lost), although not depicted as successfully in the artificial lighting.

[meteorite-list] Comet 2013 A1 (Siding Spring) Will Make A Very Close Approach To Mars In October 2014
http://neo.jpl.nasa.gov/news/news179.html Comet 2013 A1 (Siding Spring) will make a very close approach to Mars in October 2014 NASA/JPL Near-Earth Object Program Office March 5, 2013 On Oct. 19, 2014, Comet 2013 A1 (Siding Spring) will pass extraordinarily close to Mars, almost certainly within 300,000 km of the planet and possibly much closer. Our current best estimate has it passing about 50,000 km from the surface of Mars. This is about 2.5 times the distance of Mars' outermost satellite Deimos or less than twice the Earth close approach distance of 2012 DA14 on February 15, 2013. Since the observation span available for orbit determination is still relatively short, the current orbit is quite uncertain and the nominal close approach distance will change as additional observations are included in future orbit estimates. Currently, Mars lies directly within the range of possible paths for the comet and we can't exclude the possibility that the comet might impact Mars. Our current estimate for the impact probability is less than one in six hundred and we expect that future observations will allow us to completely rule out a Mars impact. Although the current heliocentric orbit is hyperbolic (i.e., eccentricity greater than one), the orbit is elliptic when expressed in the frame of the solar system's barycenter. After more than a million year journey, this comet is arriving from our solar system's distant Oort cloud. It could be complete with the volatile gases that short period comets often lack due to their frequent returns to the sun's neighborhood. During the close Mars approach, the comet will likely achieve a total visual magnitude of zero or brighter as seen from Mars-based assets. The attached illustration shows the comet's approximate, apparent visual magnitude and its solar elongation angle as a function of time as seen from Mars. Because the comet's apparent magnitude is so uncertain, the brightness curve was cut off at apparent visual magnitude zero. However, the comet may get brighter than magnitude zero as seen from Mars. From Earth, the comet will not likely reach naked eye brightness but it could brighten to visual magnitude 8 as seen from the southern hemisphere in mid-September 2014. [Illustration] This illustration, prepared by Jon Giorgini, shows the apparent total visual magnitude and solar elongation angle as seen from the center of Mars Rob McNaught discovered Comet 2013 A1 Siding Spring on January 3, 2013 at Siding Spring Observatory in Australia.

Re: [meteorite-list] sharp protrusion from an iron meteorite
Hello Michael, Martin, Adam, On the contrary, in this case, scores of stones have been recovered of each meteorite, and it is no longer reasonable to donate samples of each. I know for a fact that the both of you (Martin, Adam) haven't analyzed each and every stone that you've bought that was paired to NWA 2975, so where is the line drawn? If you haven't analyzed every piece, I'm assuming that you have some way of analytically confirming the authenticity of every fragment you've offered, given your statements. Should I give a lab a single fragment to analyze, and assume the rest are real because the lab has confirmed it? If that's the case, I would gladly sell the fragment in the lot I purchased that wasn't paired with NWA 7034 -- as NWA 7034. After all, the lot of fragments would be paired with NWA 7034 via analysis. Or did you donate samples from each Tissint that both of you bought? I know at least Martin sold quite a bit of it, but I have the feeling that he didn't donate 20% of his acquisitions. Adam, I assume you bought some. Since the stones *could* have been similar finds, why didn't you follow the procedure with that meteorite? Or is that meteorite so obviously all 'the same' that it wasn't done? When can someone decide that? No, I'm sorry, guys. If it's one or two stones and they could be distinct meteorites, sure. NWA 2975 was thousands of small stones, and we can all recognize the fusion crust, shock veins, and maskelynite grains. NWA 7034 and pairings have a brecciated texture just as unique. And since I already have analytical data confirming the 2975 (and will soon have the data on the 7034 pairing), I get the cheap shots from you dealers, but...eh. I get it. You're not even questioning the material, either of you. You're just saying that I need to donate the 20% tax despite the fact that the stones are all obviously paired to their respective rocks.

Well, Mike and Mike, This should make you happy, I just finished updating my site, all the Sold pieces have been removed. What took me so long?? Easy. The Tucson Show. It is something you start working on right after Christmas at the latest, packaging, pricing, writing Id Cards, then doing an inventory and packing up everything. Then there is the Show proper, that takes a month when you figure in the packing, driving down, setting the room, then tearing down, re-packing, driving back home, un-packing again and re-doing an inventory. Yes I do a full inventory just before and just after the Show, I am sure most of you can guess why. So now you know. Next job: posting all the new pieces.

[meteorite-list] Iowa Meteorite Crater Confirmed
http://www.usgs.gov/newsroom/article.asp?ID=3521 Iowa Meteorite Crater Confirmed USGS Airborne Surveys Back Up Previous Decorah Research US Geological Survey March 5, 2013 Recent airborne geophysical surveys near Decorah, Iowa are providing an unprecedented look at a 470- million-year-old meteorite crater concealed beneath bedrock and sediments. The aerial surveys, a collaboration of the U.S. Geological Survey with the Iowa and Minnesota Geological Surveys, were conducted in the last 60 days to map geologic structures and assess the mineral and water resources of the region. Capturing images of an ancient meteorite impact was a huge bonus, said Dr. Paul Bedrosian, a USGS geophysicist in Denver who is leading the effort to model the recently acquired geophysical data. These findings highlight the range of applications that these geophysical methods can address. In 2008-09, geologists from the Iowa Department of Natural Resources' (Iowa DNR) Iowa Geological and Water Survey hypothesized what has become known as the Decorah Impact Structure. The scientists examined water well drill-cuttings and recognized a unique shale unit preserved only beneath and near the city of Decorah. The extent of the shale, which was deposited after the impact by an ancient seaway, defines a nice circular basin of 5.5 km width, according to Robert McKay, a geologist at the Iowa Geological Survey. Bevan French, a scientist the Smithsonian's National Museum of Natural History, subsequently identified shocked quartz - considered strong evidence of an extra-terrestrial impact - in samples of sub-shale breccia from within the crater. The recognition of this buried geological structure was possible because of the collaboration of a local geologist, water well drillers, the USGS STATEMAP program, and the support of the Iowa DNR concerning research on fundamental aspects of Iowa geology, said McKay. The recent geophysical surveys include an airborne electromagnetic system, which is sensitive to how well rocks conduct electricity, and airborne gravity gradiometry, which measures subtle changes in rock density. The surveys both confirm the earlier work and provide a new view of the Decorah Impact Structure. Models of the electromagnetic data show a crater filled with electrically conductive shale and the underlying breccia, which is rock composed of broken fragments of rock cemented together by a fine-grained matrix. The shale is an ideal target and provides the electrical contrast that allows us to clearly image the geometry and internal structure of the crater, Bedrosian said. More analysis of the data will provide additional detail. These data show the impact as a nearly circular region distinct from the surrounding area to a depth of several hundred meters. These data, when coupled with physical property measurements on drill core samples, will form the basis for modeling efforts to constrain the impact geometry and energy of the meteorite, said Dr. Andy Kass, a USGS geophysicist working on the effort. The Iowa and Minnesota airborne geophysical surveys are targeting an igneous intrusion, known as the Northeast Iowa Igneous Intrusive complex, that may be similar to the Duluth layered igneous complex exposed in the Lake Superior region of northern Minnesota. Known copper, nickel, and platinum group metal resources were deposited during the formation of the Duluth complex. Both of these complexes are associated with a large structural feature known as the Midcontinent Rift, which is exposed in the Lake Superior Region but is covered by younger rocks as it extends to the south through Iowa, Nebraska, Kansas, and Missouri. This geophysical survey is part of a larger USGS effort to evaluate the concealed mineral resource potential of the greater Midcontinent Rift region that formed about 1.1 billion years ago. __ 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] Membrane boxes go boom?
I have been removing most of my .25g to 5g specimens from membrane boxes and putting them into gem boxes with the glass tops of 3 sq. cm, or 1 3/16 sq. It is much easier to see the specimen through glass then the plastic. I put a label, written in pencil, inside under the foam. Another stick-on-label goes on the outside bottom. I also put a section of Intercept Corrosion copper material inside, under the foam bottom. The foam is covered with a cloth that is black on one side and white on the other, giving you a choice. I attended a museum talk on preservation of mineral specimens and labels some many years ago, and learned that pencil will outlast even India ink. Most inks will fade away in less then a century, but pencil will last as long as the paper lasts. I also use acid free paper inside the box. So the labels will last far, far longer than I will. The Intercept Corrosion material will not stop a ruster specimen from rusting away, as I tried a problem Campo (that I had just cleaned up) set inside a riker box, set directly on the Intercept material. In six months time the fractures were filled with rust. I'm just hoping that the material will help keep the usually stable meteorites from developing into a ruster while enclosed. The glass top gem boxes fit into a nice looking case that holds 32 specimens. The case cost around $14.00 plus a few bucks for the 32 box divider. I bought them at the Tucson Show in 2012. For problem meteorites (rusters) both iron and stony, I recently started using the Australian museum method of meteorite preservation, using Al foil and sodium carbonate in hot, distilled water. I use a crock pot to treat the specimens that will fit into it. I set the crock pot heat on high. I mix up the sodium carbonate and warm water in the pot. I slowly warm up the meteorite in an oven (don't want any temperature shock). I wrap the meteorite in Al foil that I have holed with a fork, so the water can move around the specimen. Then I set the warmed specimen into the crock pot and leave the specimens in for an hour or so. I agitate the water every 15 minutes or so, and sometimes add a little more sodium carbonate. LEAVE the crock pot lid OFF, as some gases are produced. I set the crock pot under an open window. And NO! I don't reuse the crock pot for my winter soup. Always wear eye protection and rubber gloves and follow the normal safety rules. Check out the Australian museum site or the meteoritemarket/galvanic site for more info and the mixture formula. Cheers, Fred Hall A completely unofficial count: Of the 12 membrane boxes I have, about half of them are going cloudy. All but one are meteorites; the other is a Louisiana opal (sandstone matrix). Fortunately, none of the professional displays (enclosed labels) or specks it would be problematic to rebox (Martians) have decayed yet, although that may be coming. I mainly use the membrane boxes when I have a specimen whose aesthetics are enhanced by being able to see (through) both sides, or if it came that way. If you use membrane boxes to create those nifty display boxes with elaborate inside labels, you may want to take their apparent shelf life into consideration. My meteorites are not in a climate controlled area, although once a specimen goes in a gem jar or box, it generally stays there and has limited exposure to the outside air. Best!

Also, if you live in a highly humid environment like I do, then you don't want to be using membrane boxes for certain kinds of specimens because they will trap the humidity inside.

Six months later it was listed again and has been relisted a number of times to this day and is still for sale on his website.

Re: [meteorite-list] sharp protrusion from an iron meteorite
Martin, All, Personal jibes aside... Certainly -- I'll let others decide if this is enough information, and they're more than welcome to buy a sample to have it tested. I have no doubt that everything I'm offering is authentic, but everything I offer is of course backed by a full money-back guarantee. One that I will actually honor. I find it perhaps most amusing that you're not even saying that the samples I'm offering aren't paired with NWA 7034 or NWA 2975. If you are well familiarized with meteorites, I'm certain that you can tell that they're paired as well, from the photos alone. An analysis wouldn't tell you as much, nor would it prove the authenticity of most of the fragments that I am offering. Only a visual examination would do as much, unless you advocated polishing a side of each specimen and analyzing each one individually -- but such a burden of proof has *never* before been asked of any meteorite dealer. NWA 7034 and pairings are not just a breccia, as you describe them. The general texture of the breccia, as I have said before, is unlike any other meteorite or rock that I have ever seen in a geology or petrology class here at Berkeley. The angular, yet very fine-grained nature of the breccia is reminiscent of a few lunar meteorites that I have seen, but is generally much more homogeneous and contains much more shock-darkened fine-gained matrix. In short, I'm not really sure what you're getting at. You don't seem to be questioning the authenticity of the material Im offering. In fact, all you seem to be saying is that I should donate 20% so that I will analytically prove that one of fragments I purchased is indeed paired with NWA 7034 (or NWA 2975) -- despite the fact that this would say nothing about the authenticity of the other fragments (something I've mentioned several times, but that you have ignored repeatedly). You don't even address the issue of Tissint or other NWAs that apparently do not require laboratory testing in order to deem meteorites paired. For some reason, you're singling me out for these two meteorites. I'd like to hear about why that is. After all, have you noticed the self-paired NWA 2995 on ebay, currently offered by a European dealer (or at least there as of a week or so ago)? It looks authentic to me (and is relatively cheap, to boot) so I have no problem with it. I think that's where we differ in opinion. Ultimately, I value authenticity highly and trust my judgement, which has been confirmed by analytical work on numerous occasions. So, it's good enough for me. And it beats blindly selling 15 or so fragments of something as real just because one specimen has been analyzed. Though I expect data on the 7034 pairing soon enough (another fact you continue to ignore), so I really don't get what your point is. It doesn't take 20% of a meteorite to confirm a pairing, and the 2975 I'm offering was confirmed to be the same age and to share the same exposure history via argon dating. Per your analogy, they're a Porsche as much as any other Porsche is. Same stuff. Getting tired of saying the same things again and again.

Re: [meteorite-list] sharp protrusion from an iron meteorite
Hi Jason, Uff, slowly you seem to understand, what others smarter than we both got already from the 1st posting on. I say: - Your material has a different status than NWA 2975 and NWA 7034, especially a lower collector's (and therefore monetary) value. - You present your material in a way, which makes a possible buyer believe, that they are either part of the very stone(s) to which classifiers and the Meteoritical Society designed the numbers NWA 2975 and NWA 7034, or that they were confirmed by a professional meteorite scientist to be paired to them. - As long as you don't own a degree in that field and as long they don't undergo the formal classification and acceptationprocedures of the Meteoritical Society, you're not allowed to call them formally paired to these numbers, but you have to make it unmistakably clear, that this is only your personal guess. - It is good business practice to use the same conventions, how to label and name such material, like they are established among your dealers and collectors colleagues. - The way you present and describe your material breaks the binding rules of the International Meteorite Collectors Association, to which you agreed to abide as a member. In particular those, quoty quote: If members wish to sell or trade meteoritic specimens, then those items must be 'actually and exactly what is claimed.' (Merriam-Webster-Dictionary) Our members agree to adhere to the highest standards of meteorite identification and proper labelling practices. (...) I agree that it is the sole responsibility of each member to accurately describe meteoritic material for sale, trade or other related transactions without providing any misleading or false information. and especially (...) I agree that unclassified 'meteorites' purchased on eBay or other avenues from unknown sellers might not be meteorites. I will not sell or trade any meteorites I may have found (or any questionable meteoritic material) unless I first obtain verification from a meteorite expert. And especially: Verified but unclassified material should be specified as such. Meteoritical Society guidelines will prevail in the circumstance of meteorite naming and pairing (- mean point, therefore the brackets, would be, to remind you, that for you the way that Mr. Jorge authenticated his pseudo-Chelyabinsk wasn't sufficient - but nothing else did you with your Martians, i.e. to trust your source and to inspect them personally. There is the danger for you, to loose credibility in attacking others..) And see, Especially the last point regarding the Code of Ethics of IMCA makes it so comfort for both of us, cause we don't have to discuss, whether those procedures are necessary or meaningful or which properties of your material made you think to be able to verify it or whether evil Martin doesn't like your nose or whether your material is authentic ect.pp. that's all not of interest, of interest is, if you fulfill the formalities the IMCA set for you (and the standard of the MetSoc and the standard among collectors, dealers, hunters, researchers) in appraising your material. To me it seems not so. To you all seems alright. And the comfort thing for us is, we don't have to decide that, but we can leave it to that organization, to decide. So that none of has to be tempted to suppose personal motivations in that question. That's why I asked you, whether you'd like to ask IMCA together with me about that case. But so far, I got no o.k. neither a no from you :-( Best, Martin -Ursprüngliche Nachricht- Von: meteorite-list-boun...@meteoritecentral.com [mailto:meteorite-list-boun...@meteoritecentral.com] Im Auftrag von Jason Utas Gesendet: Mittwoch, 6. März 2013 02:08 An: Martin Altmann; Meteorite-list Betreff: Re: [meteorite-list] sharp protrusion from an iron meteorite Martin, All, Personal jibes aside... Certainly -- I'll let others decide if this is enough information, and they're more than welcome to buy a sample to have it tested. I have no doubt that everything I'm offering is authentic, but everything I offer is of course backed by a full money-back guarantee. One that I will actually honor. I find it perhaps most amusing that you're not even saying that the samples I'm offering aren't paired with NWA 7034 or NWA 2975. If you are well familiarized with meteorites, I'm certain that you can tell that they're paired as well, from the photos alone. An analysis wouldn't tell you as much, nor would it prove the authenticity of most of the fragments that I am offering. Only a visual examination would do as much, unless you advocated polishing a side of each specimen and analyzing each one individually -- but such a burden of proof has *never* before been asked of any meteorite dealer. NWA 7034 and pairings are not just a breccia, as you describe them. The general texture of the breccia, as I have said before, is unlike any other meteorite or rock that I have ever seen in a
