Hello Mike (and list),

Yes, the Atacama is the driest place in the world. I think I remember
hearing places where it hadnt rained in over 500 years. Dean Bessey had
some artifacts made of wood that were remarkable well preserved after
thousands of years. A few grave markers he had (or has) were really neat.

I have seen the Imilacs with the holes you are referring to. I have also
seen large Imilacs cut in half that just look yellow and with small holes
throughout and without brillant olivine. Wind seems to be only part of the
weathering process there.

If there was however a rain of nuggets I do not see how a person would tell
the difference, from a weather nugget to a weathered skeleton. Do you know
of any Imilacs with any fusion crust? Please do not take my questioning in
a negative way, I am just being curious. I have always referred to Imilac
skeletons as pieces were the olivine has weathered away, as it says in the
auctions I run.

Thanks again, Mark
