Mineral Evolution Database
Created and maintained by the Mineral Evolution Project in partnership with RRUFF and mindat.
Mineral locality data provided by mindat.org



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.

(1994) PMGFRA_243Age of the uranium mineralization in the Armorican Massif is associated with Hercynian peraluminous granites. From pg. 262: "The precise chronology of these mineralizations is not well established. The uranium veins appear to be the oldest (290-270 Ma by U/Pb dating) but underwent late remobilization processes."
