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.

Michelle_500	Silver bearing veins intrude fossiliferous limestone in the Coastal Cordillera of Iquique. Dioritic and andesitic dykes and sills form skarn, but the ore is primarily from the oxidized zone. Supergene and hypogene ore mineral assemblages have also been exploited.
