Important Update News

The RRUFF Project has been migrated to RRUFF.net. Please update your bookmarks immediately, if you have not done so.

The data on this website is already three years out of date, and the entire website will be taken offline before the end of the year.

We are grateful to NASA for the funding of this effort.




The Mineral Evolution database is currently under development.

The goal of this page is to present localities at which the mineral is found, and estimates of the oldest possible geologic age of the minerals at these localities.

Michelle_495Located on the slope of Belmont Mountain in the Big Horn Mountains, Tonopah-Belmont Mine consists of two major veins hosted in a suite of volcanic rocks. Primary mineralization was later oxidized to form a rich variety of lead, copper and zinc minerals.
Michelle_597After the death of a saguaro, a series of minerals crystallize in the rotting flesh.
Michelle_828The high-Mg andesites erupted near the end of Miocene extension in the Gila Bend region.
