I suspect most meteorites bury themselves on impact to just below the surface in soft sand/dirt so, I think the rate of 'soil covering' will make the difference, a dry desert soil is generally eroded away by winds to reveal them, and somewhere like tropical Britain (well this year at least!) has a very high rate of soil covering, from rotting plant life and water silting etc so any meteorites are more likely to be covered with a thick layer of soil in just a few hundred years, sitting in deep drier soil might actually preserve better them of course than sitting out in the rain and air?
I suspect therefore that hunting meteorites in anything other than desert or a strewnfield, will require you to dig deep! The trouble with statistics is they imply a uniform distribution of impacts, there could of course be a massive pile of meteorites in your next door neighbors house and none in the rest of the country :) ... But then of course our very own Rob Elliot finds some laying on the ground in the dampest erm.. I mean prettiest place on earth - Scotland(!) :) Cheers, Mark ______________________________________________ Meteorite-list mailing list [EMAIL PROTECTED] http://www.pairlist.net/mailman/listinfo/meteorite-list
