Mineral diversity clue to early Earth chemistry

Mineral evolution is a new way to look at our planet's history. It's the study of the increasing diversity and characteristics of Earth's near-surface minerals, from the dozen that arrived on interstellar dust particles when the Solar System was formed to the more than 4,700 types existing today. New research on a mineral called molybdenite provides important new insights about the changing chemistry of our planet as a result of geological and biological processes.http://feeds.sciencedaily.com/~r/sciencedaily/~3/7...
