Mineral Evolution Database

Created and maintained by the Mineral Evolution Project in partnership with RRUFF and mindat.

Mineral locality data provided by mindat.org

Important Update News

The RRUFF Project is being updated to improve its interface and content. The beta version of the update is accessible to the public at RRUFF.net. New data is only being added to the beta site. Please note that it is in development, and some components are not functional. Existing RRUFF.info links will resolve to the new site after RRUFF.net is officially released.

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.

Age ID	Locality Notes
Giersdorf_00000732	Uranium of the Huemul Mine is primarily found as lenticular Cu-U-V deposits hosted by the Huemul Member of the Diamante formation. Orehosting facies are grey fluvial sandstones and conglomerates filling anastomosing paleochannels incised into pink pelitic beds.
