Re: [meteorite-list] Tata-Foumzgit Martian Fall. (Why no lunar falls? and freshest lunar?)
Hi Doug, Martin, and List, I know nothing of the mathematics and modeling of meteoroid impact rates, but it strikes me as anomalous (statistically) that we don't have any lunar falls yet. It seems likely that there have been lunar falls, but they were never recovered or recognized. I agree with Martin when he says we should savor the energy that this new fall brings, because it shouldn't happen again (statistically) for another ~50 years. It felt very special to hold a sample from this fall only months after it fell to Earth. To hold the freshest Martian is far more exciting than to hold the freshest ordinary chondrite. And I would think many collectors would agree, that to experience that same thrill with a fresh lunar would be a great sequel to this Martian event. :) On a related note, a question - what is the freshest lunar on record? In terms of terrestrial age, what lunaite has the most recent fall?

Hmmm short glance on the older papers on google, tells that Dhofar 026, NWA 032, NWA 492, and I guess also SaU 169 do have terrestrial ages of 10 000years and less. -Ursprüngliche Nachricht- Von: Galactic Stone Ironworks [mailto:meteoritem...@gmail.com] Gesendet: Samstag, 14.

[meteorite-list] Tata-Foumzgit Martian Fall. (Why no lunar falls? and freshest lunar?)
MikeG Listers MikeG you said I probably should have clarified - the 21st century. So basically the last ~12 years. It's hard to find a fall (pun intended) in the last 12 years that is more important (overall) than this Martian. In terms of scientific value, Tagish Lake is probably high on the list of the most important in the 21st century. I would have to agree on Tagish Lake its very important and I would say more important then TATA in regards of scientists have no clue which parent body it came from, and the presolar grains it has and the large amount of nanodiamonds found within the meteorite. With the TATA meteorite, this makes about 79 classified meteorite from Mars. In ratio to parent body, thats alot of meteorite from one location in space considered science has no clue where Tagish Lakes parent body is. So in repect to science, TATA is just another Mars meteorite, another one to add to the growing list of Martianites :) On the other hand, ALMAHATA SITTA is by far the most signficate fall in the last 12 years Shawn Alan IMCA 1633 eBay Store http://www.ebay.com/sch/ph0t0phl0w/m.html?

So basically the last ~12 years. It's hard to find a fall (pun intended) in the last 12 years that is more important (overall) than this Martian. In terms of scientific value, Tagish Lake is probably high on the list of the most important in the 21st century. If NonCom approves it as a fall and if a lot of good research comes out of this meteorite, then it's surely one of the most interesting falls of the 50 years. Let's all cross our fingers and hope that MetSoc approves this as a named fall and that they approve it quickly once they have the data required to do so. :) Best regards, MikeG -- * Galactic Stone Ironworks - Meteorites Amber (Michael Gilmer) Website - http://www.galactic-stone.com Facebook - http://tinyurl.com/42h79my News Feed - http://www.galactic-stone.com/rss/126516 Twitter - http://twitter.com/galacticstone *** On 1/12/12, Count Deiro countdeiro at earthlink.net wrote: I only know that there are papers published making the argument that certain SNC's and Alan Hills 84001 show evidence of fossilized life forms.

Michael has asked: Would it be safe to say, that the new Martian Tata fall is the most significant meteorite fall of the 21st century, and perhaps of the last 50+ years? Not even close, Mike if by century, you were referring to falls observed through the 1900's. Take Nakhla for example. Witnessed fall. Immediate collection by experts and responsible for stirring the fuel under that most famous of all Martian argumentsis there is, or is there was ..life on Mars.
