At no point in the original press release or the original Nature article (http://www.nature.com/srep/2015/150313/srep09111/full/srep09111.html) did they suggest that there were questions about it surviving a fall to Earth. Also, there is no mention of shocked quartz, only stishovite. I don't know if stishovite should be interpreted as shocked quartz... - Yinan On Wed, Mar 18, 2015 at 7:28 PM, Graham Ensor via Meteorite-list <meteorite-list at meteoritecentral.com> wrote: > Can't see their logic that they are unlikely to survive because the > meteorites "heat up inside"....we all know that they don't? > > Graham > > On Wed, Mar 18, 2015 at 10:13 PM, Shawn Alan via Meteorite-list > <meteorite-list at meteoritecentral.com> wrote: >> Hello Listers >> >> Let hope some fossils will survive from Mars :) >> >> Enjoy! >> >> Shawn Alan >> IMCA 1633 >> ebay store http://www.ebay.com/sch/imca1633ny/m.html >> Website http://meteoritefalls.com >> >> Oddball 'Crystal' Survived Crash to Earth Inside Meteorite >> by Elizabeth Howell, Live Science Contributor | March 18, 2015 >> 07:53am ET >> >> A bizarre crystal-like mineral recently found in a meteorite that >> crashed to Earth perhaps 15,000 years ago adds more support for the idea >> that the fragile structure can survive in nature.
