I think we're talking about two separate issues here. In your original statement you first wrote: "I believe Mark is perfectly right by saying that most meteorites are lying below the soil surface." This is ~probably~ true, though you might have a difficult time proving it. ;-) Excluding the ocean, of course, most meteorites do not penetrate the ground, since most meteorites are small, and their terminal velocities are thus far from sufficient. *If* most meteorites are indeed buried, it is due to earthly processes in the centuries/millenia following a fall. Now, you went on to say: "I did not make any compiling but I guess if you go through all the Met. Bull's reporting meteorite FINDS, I am pretty sure that about (at least ?) half of them were found through plowing some field." This is a second issue, that of recovery efficiency, and this was the point I was addressing. Without even counting, I can safely predict that less than 10% of all meteorite finds were buried finds. It might even be less than 5%. Cheers, Rob ______________________________________________ Meteorite-list mailing list [EMAIL PROTECTED] http://www.pairlist.net/mailman/listinfo/meteorite-list
