Something I don't quite understand

Tom Brosz — 2/5/2004 12:59:45 AM (archived)

Olivine is not that uncommon on Earth. In fact, I think it's one of my birthstones. Yet there is water, rain and moisture on Earth, and an olivine gem doesn't seem to dissolve if you drop it in a glass of water. Why is it that olivine on Mars is considered incompatible with water at any time in Mars' history? Or am I misunderstanding the whole thing?

        Crater counts suggest volcanism ongoing on Mars. eruptions (n/t) - Robert Clark - 2/5/2004 4:31:24 PM
