[meteorite-list] TKW New Shergottite from Tata
Hi, The 0.652 gram specimen of the new shergottite from Tata sold on ebay for $315 or $483/g. I was asked what prompted my first auction on eBay. Candidly, I had been thinking about doing this for a really long time. (Facebook is next ;-) Given the number of fragments associated with this fall, and my being advised I was the first U.S. dealer to have received material, it just seemed like the perfect moment to do so. My next auction offering will include a small specimen of the most difficult to obtain Martian meteorite publicly available: Governador Valadares. Look for it later today or tomorrow. == TKW of the New Shergottite from Tata There has been a lot of banter concerning the TKW of this extraordinary meteorite. Some folks have suggested there are nearly twenty kilos and that there will be more than enough for everyone while other have expressed a more constrained amount of material. It would appear a hybrid of both statements is accurate. Numerous sources on whom I've long relied assure me we are ultimately looking at less than 10 kg of material. However, there IS more than enough for everyone! Apparently numerous meteorites shattered on impact after having struck a rocky outcropping, and exploded into THOUSANDS of sub gram fragments. If there was ever a planetary that did not have to be sliced (except for thin section needs) and where cut loss does not factor into the economicsthis is it. Even at $1000/g or more, a price point we should anticipate in the near future, specimens will be within reach. In the meantime, I still have a few specimens for sale here: http://www.rocksfromspace.org/MARS.html If you're interested in additional sub-gram specimens, please contact me off list. If you haven't already done so, you want to acquire a bit of this meteorite as soon as possible. You do not want to be one of the folks muttering I can't believe I didn't buy [Sanctioned Name] when it first hit the market Christmas 2011 All the best / Darryl __ HAPPY HOLIDAYS!!

[meteorite-list] Meteorite Quasicrystals
http://www.newscientist.com/article/dn21325-nobel-prizewinning-quasicrystal-gets-alien-status.html A Nobel prizewinning crystal has just got alien status. It now seems that the only known sample of a naturally occurring quasicrystal fell from space, changing our understanding of the conditions needed for these curious structures to form. Quasicrystals are orderly, like conventional crystals, but have a more complex form of symmetry. Patterns echoing this symmetry have been used in art for centuries but materials with this kind of order on the atomic scale were not discovered until the 1980s. Their discovery, in a lab-made material composed of metallic elements including aluminium and manganese, garnered Daniel Shechtman of the Technion Israel Institute of Technology in Haifa last year's Nobel prize in chemistry. Now Paul Steinhardt of Princeton University and colleagues have evidence that the only known naturally occurring quasicrystal sample, found in a rock from the Koryak mountains in eastern Russia, is part of a meteorite. Nutty conditions Steinhardt suspected the rock might be a meteorite when a team that he led discovered the natural quasicrystal sample in 2009. But other researchers, including meteorite expert Glenn MacPherson of the Smithsonian Institution of Washington DC, were sceptical. Now Steinhardt and members of the 2009 team have joined forces with MacPherson to perform a new analysis of the rock, uncovering evidence that has finally convinced MacPherson. In a paper that the pair and their teams wrote together, the researchers say the rock has experienced the extreme pressures and temperatures typical of the high-speed collisions that produce meteoroids in the asteroid belt. In addition, the relative abundances of different oxygen isotopes in the rock matched those of other meteorites rather than the isotope levels of rocks from Earth. It is still not clear exactly how quasicrystals form in nature. Laboratory specimens are made by depositing metallic vapour of a carefully controlled composition in a vacuum chamber. The new discovery that that they can form in space too, where the environment is more variable, suggests the crystals can be produced in a wider variety of conditions. Nature managed to do it under conditions we would have thought completely nuts, says Steinhardt.

[meteorite-list] First Meteor Shower of 2012 (Quadrantid)
Space Weather News for Jan. 3, 2012 http://spaceweather.com FIRST METEOR SHOWER OF 2012: The annual Quadrantid meteor shower peaks on Wednesday morning, Jan. 4th, when Earth passes through a narrow stream of debris from a comet thought to have broken apart some 500 years ago. The shower is expected to be strong (as many as 100 meteors per hour), but elusive, with a peak that lasts no longer than a couple of hours. The shower's radiant near Polaris favors observers in the northern hemisphere.

Re: [meteorite-list] Nobel Prizewinning Quasicrystal Fell From Space
It is funny that one of these Quasicrystals was brought here to Laughlin, Nevada for the annual UFO convention. If I thought this rock might have been a meteorite instead of part of a flying saucer's Ford big block engine, I would have made an offer. Here is a link that will take you to an image of this giant crystal featured on another low-budget cable show called UFO Hunters Supposedly, it ruined three safes while being stored here in a hotel during the convention: http://alienufoparanormal.aliencasebook.com/2009/05/08/videos--ufo-trace-evidence--real-evidence-from-bob-white-and-the-ufo-hunters.aspx Now, I will keep my an eye out for them in the field.

Now Paul Steinhardt of Princeton University and colleagues have evidence that the only known naturally occurring quasicrystal sample, found in a rock from the Koryak mountains in eastern Russia, is part of a meteorite.

Now Steinhardt and members of the 2009 team have joined forces with MacPherson to perform a new analysis of the rock, uncovering evidence that has finally convinced MacPherson. In a paper that the pair and their teams wrote together, the researchers say the rock has experienced the extreme pressures and temperatures typical of the high-speed collisions that produce meteoroids in the asteroid belt. In addition, the relative abundances of different oxygen isotopes in the rock matched those of other meteorites rather than the isotope levels of rocks from Earth. It is still not clear exactly how quasicrystals form in nature. Laboratory specimens are made by depositing metallic vapour of a carefully controlled composition in a vacuum chamber. The new discovery that that they can form in space too, where the environment is more variable, suggests the crystals can be produced in a wider variety of conditions. Nature managed to do it under conditions we would have thought completely nuts, says Steinhardt.

Re: [meteorite-list] Are Mars Meteorites Magnetic?

[meteorite-list] New 'SNC' fall
Hello list members. Anyone out there know Who classified this new SNC from Morocco? If an institution has already done the work and submitted to Met Soc then there is no need to do it again.

Re: [meteorite-list] Nobel Prizewinning Quasicrystal Fell From Space
You can see the original article here: http://www.pnas.org/content/early/2012/01/03/115109.full.pdf+html They don't really talk about the original rocks, just the sample they're working with is a few millimeters. Found in a claybed in a stream in eastern Russia. So, no fusion crust, just some metallic crystals. Back story is pretty interesting: As Steinhardt tells the story, the Florence museum had bought it in 1990 from a now-deceased private collector in Amsterdam, as part of a job lot of 10,000 samples. Bindi tracked down the collector’s widow, who agreed to let the scientists look at secret diaries that included details of an ‘exchange’ — or smuggling operation — in Romania. After further detective work, including talking to a former Russian secret-service agent who had helped to smuggle the rock out of the country, the scientists found V. V. Kryachko, the man who in 1979 had first dug the rock from sticky clay in the remote Chukotka region of Russia, just across the Bering Strait from Alaska. Steinhardt and his colleagues trekked out to Chukotka last summer to examine the site for signs of quasicrystals, but have not yet published their findings - http://www.nature.com/news/the-quasicrystal-from-outer-space-1.9728#/b1 -Yinan On Tue, Jan 3, 2012 at 8:55 PM, cdtuc...@cox.net wrote: List, Hats off to them for this fabulous discovery .
