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The data on this website is already three years out of date, and the entire website will be taken offline before the end of the year.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

Locality Notes from all Ages at Locality:

Age ID	Locality Notes
Giersdorf_00000655	The Quistiav locality is found within the Pontivy region of France. It is responsible for producing 400 tons of Uranium metal. Uranium in the Pontivy district is usually found intragranitic, the granite is cut by a system of transverse mineralized fractures, preferentially located on the northern part of the Massif. It is within the fractures that the Uranium can be found.
