Re: [meteorite-list] AD: Advanced Iron Collectors
Martin: Are you talking about advanced age, or advanced resources? I have found that I have turned a corner where I collected stoney meteorites, but now have developed a taste for Irons. Yes, I know it leaves a funny taste in your mouth, but what the heck. It probably is because I have found a lot of Whitecourt Irons, and then it becomes personal. What do you have in mind? Hopefully not a special deal in Africa...

[meteorite-list] Help please. How to get large pieces Weighed
Thanks to all for the input, I went to Mail Boxes etc. and they offered to weigh them for free. I think their scale is accurate to around 100 grams. These meteorites will be for sale, and I don’t want to short anyone. Good thing is their not lunar, or anything to special that way, so this should work…..I hope Thanks again, Bill Hall __ Visit the Archives at http://www.meteoritecentral.com/mailing-list-archives.html Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
Re: [meteorite-list] SUBJECT BOX
This (below) involves a thread in which there Is not one word about using a magnet cane, Yet they were all posted with the subject Box reading "Magnet Canes are evil" Or "Magnet Canes are evil DON'T THINK SO" Please change the subject box when the Subject changes. I may not want to read 45 posts about The debate re the pros and cons of using a magnet Cane but may be very interested into what the topic such A thread may morph.

Re: [meteorite-list] Magnet canes are evil
Hi Count, Greg and List, Rare earth magnets are manufactured by the Chinese in a wide variety of shapes and sizes, including some flat discs that would fit very fell on the bottom of a shoe or inside the shoe under the insole. ;) Best regards, MikeG On 8/24/10, countde...@earthlink.net wrote: > Thanks, Greg > > Very cool.

Thanks, Greg Very cool. You can hide it from the big bad BLM nazis. I carry a telescoping magnetic mechanic's part recovery wand to which I taped the exact same diameter neomydium on the end.

Re: [meteorite-list] Magnet canes are evil
List: When I got into meteorite hunting and decided to make a magnet cane, I thought about how to make it and this show "Becker" came on; it starts Ted Dansen as a grumpy Doctor and noticed that the blind man walked across the street and into a diner and sat at a table. As he sat, he folded the cane and set it in a backpack. And it hit me - What a great design for a meteorite hunting stick. I should make a magnet cane out of a folding blind mans walking cane. So I bought one at a medical store and refined the bottom with glue and a screw to attach the magnet and made my very own meteorite hunting cane. It's great because I can fold it and put it in my back pocket or my backpack. It's also good for travel - like on a plane. It looks very much like this one. http://www.mountainside-medical.com/products/Blind-Mans-Walking-Cane-50-Inch-long.html It has always fascinated me to look at all the different meteorite hunting canes there are, and how each person puts their individuality in making them.

[meteorite-list] Roach Dry Lake question
[Sorry for the premature send, and possible repeat of this post] Hi Adam, > I have a question. Does anybody know why Roach Dry Lake is closed in > Nevada? Last time I was there, it was closed by some development corporation, presumably in expectation of building a Southern Nevada Supplemental Airport, pending an environmental impact assessment. I just found the following document online: http://edocket.access.gpo.gov/2008/pdf/E8-17807.pdf which may answer some of your questions (haven't read all of it yet). I was under the impression that it only affected the portion of Roach west of the RR tracks -- can't very well have aircraft runways crossing those tracks! Does anyone know if access to the east side is still allowed? --Rob __ Visit the Archives at http://www.meteoritecentral.com/mailing-list-archives.html Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list

Go Guido Go. Very well put. As Daiid Vann put it earlier in his post. . Magnets don't always kill meteorites.

Adam, I think the Antiquities Act is being abused much like the Commerce Clause has been. It was about archaeological sites, but now it's anything the government perceives as a possible way to get money. In my experience interpretation and enforcement is arbitrary, and will continue to be as long as the law is vague and there are no legal challenges which will result in guidelines.

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

[meteorite-list] Solar system may be 2 billion years older than we thought
>From ASU: http://asunews.asu.edu/20100823_bouvier Timescales of early Solar System processes rely on precise, accurate and consistent ages obtained with radiometric dating. However, recent advances in instrumentation now allow scientists to make more precise measurements, some of which are revealing inconsistencies in the ages of samples. Seeking better constraints on the age of the Solar System, Arizona State University researchers Audrey Bouvier and Meenakshi Wadhwa analyzed meteorite Northwest Africa (NWA) 2364 and found that the age of the Solar System predates previous estimates by up to 1.9 million years. By using a dating technique known as lead-lead dating, Bouvier and Wadhwa were able to calculate the age of a calcium-aluminum-rich inclusion (CAI) contained within the Northwest Africa 2364 chondritic meteorite. These CAIs are thought to be the first solids to condense from the cooling protoplanetary disk during the birth of the Solar System. The study’s findings, published online on August 22 in Nature Geoscience, fix the age of the Solar System at 4.5682 billion years old, between 0.3 and 1.9 million years older than previous estimates. This relatively small revision to the currently accepted age of about 4.56 billion years is significant since some of the most important events that shaped the Solar System occurred within the first ~10 million years of its formation. “This relatively small age adjustment means that there was as much as twice the amount of iron-60, a certain short-lived isotope of iron, in the early Solar System than previously determined. This higher initial abundance of this isotope in the Solar System can only be explained by supernova injection,” said Bouvier, a faculty research associate in the School of Earth and Space Exploration (SESE) in ASU’s College of Liberal Arts and Sciences. “This supernova event, and possibly others, could have triggered the formation of the Solar System. By studying meteorites and their isotopic characteristics, we bring new clues about the stellar environment of our Sun at birth.” According to Meenakshi Wadhwa, professor in SESE and director of the Center for Meteorite Studies, “This work also helps to resolve some long-standing inconsistencies in early Solar System time scales as obtained by different high-resolution chronometers. However, there is certainly room for future studies. In particular, it will be important to conduct high precision chronologic investigations of CAIs from other pristine meteorites. We also need to understand the reasons for why the CAIs measured previously from two other chondritic meteorites, Allende and Efremovka, have yielded younger ages.” One significant aspect of this study is that it is the first published lead-lead isotopic investigation that takes into account the possible variation of the uranium isotope composition. Earlier work conducted in Wadhwa’s laboratory by ASU graduate student Gregory Brennecka, in collaboration with SESE professor Ariel Anbar, has shown that the uranium isotope composition of CAIs, long assumed to be constant, can in fact be highly variable and this has important implications for the calculation of the precise lead-lead ages of these objects. Using the relationship demonstrated by Brennecka and colleagues between the uranium isotope composition and other geochemical indicators in CAIs, Bouvier and Wadhwa inferred a uranium isotope composition for the CAI for which they reported the lead-lead age. Future work at ASU will focus on development of analytical techniques for the direct measurement of the precise uranium isotope composition of CAIs for which lead-lead isotopic investigations are being conducted. “Our work can help researchers better understand the sequence of events that took place within the first few million years of the Solar system formation, such as the accretion and melting of planetary bodies,” Bouvier said. ”All these processes happened extremely rapidly, and only by reaching such a precision on isotopic measurements and chronology can we find out about these processes of planetary formation.” Nikki Staab, nst...@asu.edu 602-710-7169 School of Earth and Space Exploration Gary Fujihara Big Kahuna Meteorites (IMCA#1693) 105 Puhili Place, Hilo, Hawai'i 96720 http://bigkahuna-meteorites.com/ http://shop.ebay.com/fujmon/m.html (808) 640-9161 __ Visit the Archives at http://www.meteoritecentral.com/mailing-list-archives.html Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list

[meteorite-list] Meteorite Top Sites 100 List - Update
Hi Listees (and especially webmasters), The Meteorite Top Sites list is taking shape and we now have 11 websites participating. As expected, all of the sites are receiving much more traffic than they are sending to the list. The tally would be even higher, but I have manually re-ranked the list several times in the last week while making changes to the look and settings of the list itself. We have a nice mixture of meteorite information sites and dealer websites, and I would like to see more participation. From my recent research for my page rank report, I know there are easily over 90 different meteorite-related websites on the web, and about half of these are dealers. If you have a meteorite site and you could profit from more visitors, then please join the Meteorite Top Sites list. This is not a mailing list, it is a "Top 100 List" script which ranks sites according to traffic counts (which are reset weekly to give everyone a chance of ranking high), and it allows visitors to post ratings or comments for sites - but it is not a discussion board and it is not meant to replace or compete with Art's Met List, the IMCA, or any other established meteorite entity - in fact, the purpose is the increase traffic (and success) for all sites that participate. As sponsor of the list, I charge no fees and I make no money from advertising - this is 100% non-profit and being done on my own time. The only thing I am getting from this, personally, is a bit more traffic. (the same as everyone else who is participating). The Top List is now indexed on Google and Bing, and traffic is starting to increase. If the list ever swells past 20-30 members, we should really see a strong increase in traffic for participating sites. So I cordially invite everyone with a meteorite-related website to sign up for the list. Here is what's involved : 1) you go to the site via the join or add-site link. You give your name, the website address, and your email address for verification purposes - your email address is kept 100% confidential. You are sent a verification email, and you click on that to activate your account. 2) after verifying and activating your account via email, your site goes into an approval queue, where I personally approve or deny the site - this is to keep out spammers and scammers. After I approve your website, you will receive instructions on how to exchange links between the list and your site. 3) Upload a banner for your website to the list, and sit back to watch your traffic start to increase. It's that easy. Join here - http://meteorite.gotop100.com/members/signup.php See the list here - http://meteorite.gotop100.com/ If you have any questions about the list or how to join, feel free to contact me off-list at - m...@galactic-stone.com And I promise this won't become a regular appeal for members. I just wanted to put this out there again to help get it off the ground. So far only 10 sites besides my own have signed up, so the ratio is pretty small. With more participation, this could be a viable (and free) traffic generator.

Re: [meteorite-list] Magnet canes are evil DONT THINK SO!
Hello All, Eric Actually has something of a valid point, I think. I've heard that using a rare-earth magnet on a planetary meteorite can realign the magnetic domains within the stone. While that may not seem too important, some people have studied the magnetic properties of martian meteorites as a means of trying to understand Mars' ancient magnetic field; the magnetic domains within older martian basalts were set in stone when those rocks cooled billions of years ago. But I'm not sure if this is entirely true. If anyone out there might have some input on this, I'd be curious to hear more about it.

Believe it or not, It is illegal to carry a magnet on a stick or any other searching device into some areas of California for the purpose of locating a resource. Get caught with a magnetic cane or no permit on Ivanpah Dry Lake bed for example and you will be in big trouble with the BLM. Any place that has artifacts in California which includes most dry lake beds is now off-limits to using a magnetic cane or metal detector for searching.

I think you took what I was saying personally and the wrong way. I never said "magnets are bad". I asked questions about contamination... That said, I still use one. In certain circumstances. Does that make me an evil meteorite monger? No, and neither does it make anyone else that uses a meteorite stick an evil person. I asked the question because I don't know about magnetic properties and study of these properties in meteorites. I don't really know the importance of the magnetic property issue, hence my question to Rob, and the list.

I wasn't attacking anyone at all, I was questioning the use of magnets with relation to studying magnetic properties of meteorites and the seemingly obvious contamination using one would cause. Also, for the record, there's nothing wrong with testing a suspect meteorite to see if it "sticks" to a magnet. I do it, everyone I know does it. in fact I don't know a meteorite hunter that doesn't carry a neo mag on him/her at all times while in the field, and most times anywhere they go.

Re: [meteorite-list] Magnet canes are evil
Hi List, The evilness of magnet canes is well known throughout history. In fact, Satan uses a 3-pronged magnet cane that is often mistaken for a pitchfork. An old 14th century woodcut in the tome "Of Meteors and Devils" (trans), a depiction of Satan is clearing seen and about his feet are several imps who are pulling bits from the end of his magnet cane and dancing about with them. ;) Best regards, MikeG On 8/24/10, Matson, Robert D. wrote: > Mark wrote: > >> As soon as everyone stops using metal detectors and magnet canes >> to look for meteorites then the first Lunars in Europe or USA >> will eventually be found, until then! > > I have never used a magnet cane, nor will I ever, and I always > advise new hunters against their use.

Re: [meteorite-list] Magnet canes are evil
Magnetic canes and similar can add to, alter or destroy the magnetic imprint on a meteorite. So, however, does the Earth's own magentic field after a time (OK, a long time, but not *that* long). In general, only very recently fallen meteorites are useful for magnetic domain studies. However, a cane's effect can be restricted to measurable surface effects if the meteorite is large enough. A few magnetic studies have been done, usually on falls (e.g. Richardton, Berduc, Allende). Some have determined paleomagnetism, in spite of the overprint (which can be recognized). In fact, attempts have been made to estimate Mars' magnetic field based on the micromagnetic domains within e.g. nahklites. Unsurprizingly, most of the analyzed samples are Antarctic ones, where anthromagnetic imprints have been avoided. One of the most interesting things to come out of this is that early planetismals may have been large enough to have a dynamo, i.e. their own magnetic field. This is an interesting summary of some of what is known: Paleomagnetic Records of Meteorites and Early Planetesimal Differentiation SPACE SCIENCE REVIEWSVolume: 152Issue: 1-4Pages: 341-390 Published: MAY 2010 Weisss, et al. Abstract: The large-scale compositional structures of planets are primarily established during early global differentiation. Advances in analytical geochemistry, the increasing diversity of extraterrestrial samples, and new paleomagnetic data are driving major changes in our understanding of the nature and timing of these early melting processes. In particular, paleomagnetic studies of chondritic and small-body achondritic meteorites have revealed a diversity of magnetic field records. New, more sensitive and highly automated paleomagnetic instrumentation and an improved understanding of meteorite magnetic properties and the effects of shock, weathering, and other secondary processes are permitting primary and secondary magnetization components to be distinguished with increasing confidence. New constraints on the post-accretional histories of meteorite parent bodies now suggest that, contrary to early expectations, few if any meteorites have been definitively shown to retain records of early solar and protoplanetary nebula magnetic fields. However, recent studies of pristine samples coupled with new theoretical insights into the possibility of dynamo generation on small bodies indicate that some meteorites retain records of internally generated fields. These results indicate that some planetesimals formed metallic cores and early dynamos within just a few million years of solar system formation. Contact me off-list if you are interested in the PDF So, best not to pick them up by magnetic cane if you want paleomagnetic data. But note, plenty of meteorites that cannot be picked up by a magnet have relic magnetic fields in the stones, whether in tiny ferromagnetic bits or in the other minerals (magentic microdomains). Also, unless the original signature has been destroyed, it is still just possible to recover the signature from "beneath" a stronger, localized imprint caused by a magnet.

Re: [meteorite-list] Magnet canes are evil
List: I use a magnet cane - in fact it it super strong. But I must point out that I do not rely on it. I use my eyes mostly. I look for the rock shape, texture and color. I think the shape is very important. I check if it is smooth and that the edges are rounded - like a partly polished rock. It is bad to depend on a magnet for a number of reasons (as Rob pointed out) also if the rock is embedded in a hard clay, a magnet will not pick it up if it's an LL or an old weathered L or even H. I have found meteorites like this - some I had to remove from the clay to test how magnetic it was. So as Rob points out - Your eyes are the best tool you have. Now as to the reason I like a super stonge magnet is in case I find an achondrite. I have bought some and often they stick weakly to a magnet - well if I see an odd smooth looking rock that's a little out od place, I'll check it with my magnet to see if it sticks slightly... believe me I have a lot of iron rich basalt and silicas with magnetite in them in my garage, but I think it's worth it. Now if it's something that has no magnetism (R-chondrite) then I have to rely on the eyes again. I metal detector is good in places with many many rocks or the meteorites are buried - Franconia and Gold Basin. It's funny, But I actually think most of my dry lake finds were found with my eyes and not the magnet cane, but I think the more tools you have the better - you just need to learn how to use them in the best ways.

Re: [meteorite-list] Extremobacteria
Hi, Gang, First, it was Streptococci -- bacteria, not viruses -- that were found in the Surveyor camera body. They were discovered, needless to say, after pieces were returned to Earth. That raised the question of contamination in the Receiving lab. Much was made of it at the time, but after much review of the evidence and the circumstances, the possibilities are as follows. 1. The camera was contaminated before it went to the Moon. Surveyor scientists discovered a breach of sterile procedure in the preparation of the comers, they say, so the microbes could have gone to the Moon and survived two years. 2. The astronauts brought it back in a nylon duffel bag (like old socks); it was not sterile sealed, so could have been contaminated while being returned. 3. We'll never know because the camera was put on public display and is now hopelessly contaminated. We can't test again. http://en.wikipedia.org/wiki/Reports_of_Streptococcus_mitis_on_the_moon That said, I have no doubt that Deinococci and the Rubrobacter genus of Actinobacteria could survive any amount of cosmic radiation. It's why they call them "extremophiles." They just eat it up. And, remember, Google is your friend... Sterling K.

Re: [meteorite-list] Magnet canes are evil
Curious about the magnetic properties of meteorites as well. We all know that you can magnetize metal just by placing it near a powerful magnet. I read yesterday in Richard Kowalski's post about Brother Guy Consolmagno's visit to Tucson. Dr Concolmagno's research also includes the study of magnetic properties of meteorites. I'm sure he's not the only person to study these properties, but it got me to thinking about it.

Re: [meteorite-list] Search for first U.S. lunar meteorite
It is true that if you depend on a magnet, you will not find a planetary meteorite. I found the small 50 gram half of NWA 1195 in a Moroccan discard pile, same for other planetary pieces. It was placed there because it was not magnetic and did not have a crust. They sent rocks that bothered them from discard piles to have us look at them. They have an outstanding memory and when we told them that one of the stones was an incomplete Martian and forwarded them an image of it, they searched and found the larger half a few meters from where the the first was found. We told the Moroccans to send us any out of place stones and stop depending on magnets. They soon began to put more value on the visual characteristics which in turn increased their yield greatly. The problem is that a lot of terrestrial rocks started showing up in our loads and we had to explain why they were not meteorites. This process took years until they became experts at finding them. It cost my brother, Greg and I tens of thousands of dollars to study these pieces with an occasional surprise showing up. We would then patiently explain what characteristics to look for when a winning piece showed up. Being able to recognize Lunar/Martian meteorites in the field is a process in which the Moroccans have become experts. The yield has dropped significantly the last few years so most of the readily accessible areas have been searched. They have to go further and further out in order to find them and there comes a point where this becomes logistically impossible. Just over a decade ago, no planetary meteorites were recognized as coming from NWA. It is time to search North America before it becomes off-limits.

[meteorite-list] More on Chladnite (Was: Rocks from Space Picture of the Day - August 24, 2010) - Part 2
BURKE J.G. (1986) Cosmic Debris, Meteorites in History, Chapter 4, p. 121: Chladnite: Again, it was an observation by Charles U. Shepard that paved the way toward the identification of the pyroxenes. In 1846 he described a mineral which, he wrote, "is a ter-silicate of magnesia...[and] forms more than two-thirds of the Bishopville stone". He named the mineral chladnite "in honor of Chladni, the scientific founder of this department of knowledge." Two years later Shepard reported his analytical results: 70 percent silicic acid, 28 percent magnesia, and 1 percent soda, so that the ratio of oxygen in the magnesia to that in the silica was 1 to 3. In 1851 Sartorius von Waltershausen analyzed a fragment of the Bishopville meteorite and arrived at about the same results, but also found 1.5 percent alumina. Though making errors in his calculations, Sartorius did produce the correct formula - MgO,SiO2; however, he postulated that chladnite was a kind of wollastonite, in which magnesia substituted for lime. The issue was confused further in 1861, when Rammelsberg found by analysis almost 3 percent alumina, 35 percent magnesia, and only 57.5 percent silicic acid. Doubting the existence of a definite mineral, Rammelsberg did not attempt to devise a chemical formula. Meanwhile, Shepard in 1854 described the Tucson iron meteorite and speculated that certain inclusions were chladnite. J. Lawrence Smith immediately corrected him, pointing out that the inclusions were actually olivine, and added a note that he suspected "chladnite is likely to prove a pyroxene". At about the same time, in 1855, Gustav A. Kenngott, professor of mineralogy at Zurich, published a memoir giving details of the minerals of what he termed the "augite group" of the pyroxenes. One member of the group was enstatite, which, Kenngott wrote, was a bisilicate of magnesia, was "augitic in crystallization," and had the formula 3MgO,2SiO3. In 1861, when Kenngott saw Rammelsberg's analysis of chladnite, he insisted that the mineral was identical with enstatite. Smith then made two analyses of the Bishopville meteorite and reported in 1864 that chladnite consisted of 60 percent silica and nearly 40 percent magnesia. He agreed with Kenngott that the mineral was the magnesian pyroxene, enstatite, and accepted Kenngott's formula, in which the oxygen content of the magnesia to that of the silica was 1 to 2. Both Rammelsberg and Maskelyne acted to clarify the formula of enstatite, and through his work on the Breitenbach, Bustee, and Manegaon meteorites, Maskelyne recognized the existence of solid-solution series that included enstatite and bronzite. By the 1870s mineralogists began to report regularly these constituents in meteorites. __ Visit the Archives at http://www.meteoritecentral.com/mailing-list-archives.html Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list

Re: [meteorite-list] Help please. How to get large pieces Weighed
Hi Folks, I just thought of something that seems overly-obvious - the bathroom scale. It's not accurate to the level required for selling micromounts, but for big 70kg specimens, getting within a pound is probably good enough for most buyers - people aren't exactly paying by the gram when you are buying a HUGE specimen. In the past, I have weighed big boxes with telescopes in them using the bathroom scale - and then used the result as the shipping weight, with no issues. First I would weigh myself, then I would weigh myself holding the package - then subtract my own weight and you have the remaining weight of the parcel - if your scale is accurate, that should get you close - assuming you can hold a 100+ pound specimen while balancing on the scale.

[meteorite-list] NWA 6291 info
For those interested or who purchased some of this, I got an email from Tony Irving with more detailed info on the NWA 6291 angrite. "NWA 6291 Achondrite (angrite, metal-rich) Annealed breccia composed of Al-Ti-diopside (Fs10.8+/-0.05Wo53.0+/-0.05, FeO/MnO = 114, Al2O3 = 7.7-7.9 wt.%, TiO2 = 1.3 wt.%), calcic olivine (Fa40.9+/-0.05, FeO/MnO = 94-95, CaO = 1.3-1.5 wt.%), pure anorthite, Cr pleonaste spinel, altered kamacite (~8 vol.%) and troilite. Anorthite occurs as large (up to 3 mm) angular clasts and also as thin coronas around spinel grains. Secondary terrestrial weathering products include iron hyroxides (in veinlets) and minor calcite. This specimen is paired with NWA 2999 (and other stones)" Many thanks go out to Tony Irving, he is a great guy to work with!

Re: [meteorite-list] Extremobacteria
Granted but, the moon is still a relatively sheltered place though, nothing like deep space. Additionally Virus's have a significantly lower cross section to cosmic radiation than bacteria do. A few hundred days in low earth orbit is nothing like a few hundred million years, which is about the time Martian rocks take to arrive here, so are we any further forward in knowing the survivability of microbes in meteorites? It's interesting research, my only caveat is this doesn't necessarily mean bacterial can thrive/survive long-term in [outer space].

Re: [meteorite-list] Search for first U.S. lunar meteorite
Yes it's got to be a massive factor in skewing the statistics, plus some lunars from first glance look like some of the native rocks of the USA and Europe which won't help. Factor all this in and it's the reason we haven't found any yet, statistically 3 or 4 USA lunar finds is quite easy to account for not being found. Remember Antarctica meteorites are often found visually rather than by 'magnet snap' this could maybe explain the reason there are more lunars found up there. >. Most newbie hunters ignore anything that doesn't stick to a magnet. I wonder how many lunars have been passed over in favor of an ugly, weathered OC? LOL yes very true, but I also even wonder how many O'C's have been passed over that didn't stick to the cane (many small ones or LL types don't immediately stick to a small magnet!). if in doubt pick it up and bring it home I guess!

Excerpts: Chladnites This combination of minerals has been found in only one meteorite, Bishopville. The stone is coarse grained and consists mostly of friable snow white enstatite. Rose observed other white grains, but could not identify them. I find these to be plagioclase. The third constituent is pyrrhotite. The stone's crust has a marbled appearance, being partly colorless, partly black, white, bluish, and gray. Enstatite occurs in large and small grains, mostly large. I observed distinct crystal boundaries on one of the small grains, ...The grains are cut by many fine, irregular cracks ... Plagioclase is usually attached to the small enstatite grains...Pyrrhotite forms large and small grains... The analysis of Rammelsberg (1861), which found Al2O3, CaO, and alkalis in small amounts, in addition to the ingredients of enstatite, is in full agreement with the microscopic description just given. Rose also reports small amounts of nickel-iron and a black mineral that sometimes fills fine cracks. Breaking the stone along such cracks, I observed a shiny material, similar to that in meteorites to be described later, in which the veins consist of iron, pyrrho- tite, and silicate glass... Diogenites This class differs little in mineralogy from the preceding one. The main constitutent is bronzite or hypersthene; these minerals and enstatite are members of the same series. Therefore the d i s t i n c t i o n between *chladnite* and *diogenite* depends only on c o n t e n t of f e r r o u s o x i d e. -- Regards, Bernd __ Visit the Archives at http://www.meteoritecentral.com/mailing-list-archives.html Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
Re: [meteorite-list] Rocks from Space Picture of the Day - August 24, 2010
Hi Richard, "Chladnite" is a synonym for enstatite and was a synonym for the aubrites among the meteorites. That mineral name was introduced by Charles U. Shepard (1804-1886) in 1846 when he firstly observed enstatite in the 1843 fallen Bishopville aubrite, to honor Ernst Florens Friedrich Chladni as the founder of modern meteoritics. Best!

[meteorite-list] New Meteorite Impact Crater Found
Hi, there If you are interested in collecting meteorite fragments from a presently undiscovered impact crater please give me a call. I am a South African citizen, and I have been using goolge earth for a separate research, when I suddenly recognised a meteor crater. But the problem is that, here in South Africa the law is different, if you are an unqualified aercheologist, you can't collect anything from fossils, meteorite etc. You have to report it to goverment museum. So good people I'm sorry, I won't report or give any details about it, unless I will get something in return, obviously I need money as well. I have contacted the museum but they told me that it belong to the goverment. So I just left it there I never continued, It would rather stay undiscovered as it is rather than giving my find to someone who will profit with it while I didn't. So if you want to get it position and need to explore it, just contact me on my cellphone number +27 0769989632. And maybe as someone proffesional you can convince them to get permission to explore and collect.
