The larger and older a crater is, the less likelihood there are surviving meteorites found. "Older" is understood owing to weathering. Larger is owing that when such vast amount of kinetic energy gets converted to heat bonds will be sheered at the molecular and atomic level. So very little remains.
Be it remembered in the case of Canyon Diablo , which may really be a splintered sister swarm off the meteor crater impactor: It has been estimated somewhere that 99.99% of that impactor was turned into a metallic fog some of which condensed into the spheroids.--Literally vaporized and a very hot vapor at that. Elton from vic Dayton Ohio. PS: The recovery of a single OC micro fragment in the ocean 65my after Chuxilub is unconvincing that it was a meteorite from that event. So let me preempt any suggestion that Chuxilub is a crater with meteorites. ______________________________________________ Visit the Archives at http://www.meteoritecentral.com/mailing-list-archives.html Meteorite-list mailing list [email protected] http://six.pairlist.net/mailman/listinfo/meteorite-list
