That brings up another thought-- with a magnet or metal detector, you'll find the loose metal parts of the meteorite, but what about the loose olivine crystals part? Those fragile, shattering portions should have flinging out a rain of olivine crystals. Anyone ever take some of the soil from around any of the finds, scoop it onto a screen, run a hose over it, and see if you come up with any loose crystals? Maybe not as cool (and valuable) as finding the big iron, but it'd still be interesting to me, at least-- (I have no practical expereince meteorite hunting, but when it comes to spending many hours sifting through sand for tiny shells and fossils, I've BTTTGTTS, see linked photo for a few of 'em http://webpages.charter.net/garrison6328/shells_smaller.jpg ) ______________________________________________ Meteorite-list mailing list [email protected] http://six.pairlist.net/mailman/listinfo/meteorite-list
