My meteorite collecting (and, really, awareness that there even is a meteorite collecting market) began after the Sahara "gold rush" started, and my collection strongly reflects that. How old those really weathered meteorites coming out of NWA are is interesting (and a data point in determining fall rate). I already knew that the Sahara was much wetter in the past-- but a data point that it was much wetter as recently as 4,500 years ago is interesting-- and I would think it would push the possible age for the weathered meteorites forwards (some, I believe, have been estimated to be 10s of thousands of years old). ______________________________________________ http://www.meteoritecentral.com Meteorite-list mailing list [email protected] http://six.pairlist.net/mailman/listinfo/meteorite-list
