Earth's rarest minerals catalogued

None of 2,500 species described is known from more than five locations, and for a few of them the total global supply could fit in a thimble.
The researchers say it is important to hunt down these oddities because they contain fundamental information about the construction of our planet. Some will also undoubtedly have properties that are useful in technological applications.
The list appears in a paper about to be published in the journal American Mineralogis

Minerals evolved along with life
The number of minerals in the solar system has increased through time, and some minerals on Earth exist because of life

Think evolution is something that happens only to plants and animals? Think again, say scientists who point out that evolution - change through time - happens in the mineral kingdom as well. As our solar system has aged, the number of types of minerals it contains has burgeoned from only a dozen or so to well over 4,000.
And about two-thirds of today's minerals either directly or indirectly evolved thanks to the presence of life on Earth.

An exhibit of natural mineral wonders, "Minerals: The Duval Collection," is on display through Mary 26 at the Museum of the Rockies.
