Cavosie, A.J., N.E. Timms, T.M. Erickson, and C. Koeberl, 2017, New clues from Earth’s most elusive impact crater: Evidence of reidite in Australasian tektites from Thailand. Geology Published: December 20, 2017 DOI: https://doi.org/10.1130/G39711.1 https://pubs.geoscienceworld.org/gsa/geology/article-abstract/525531/new-clues-from-earth-s-most-elusive-impact-crater? " Here we report new evidence of a rare high-pressure phase in Australasian tektites that further constrains the location of the source crater. The former presence of reidite, a high-pressure polymorph of zircon, was detected in granular zircon grains within Muong Nong–type tektites from Thailand." "The data presented here place further constraints on the distribution of high-pressure phases in Australasian tektites, including coesite and now reidite, to an area centered over Southeast Asia, which appears to be the most likely location of the source crater." An impact capable of producing such a large strewn field certainly must have devastated prehistoric fauna and flora of Southeast Asia. I wonder if anyone has looked into this aspect of this asteroid impact. Yours, Paul H.
