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.

Locality Name:
Golden Fleece Mine, Lake City, Lake City District (Lake District), Hinsdale Co., Colorado, USA

Oldest recorded age at locality: 30.5
