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 Notes from all Ages at Locality:

Age ID	Locality Notes
Michelle_804	Powwow Member of the Hueco Limestone
Michelle_805	Supergene silver-bearing ores are found principally along small fractures or near surface faults that generally are conformable with the bedding. The ores probably formed at low temperatures during Basin and Range extension
Michelle_806	Tertiary igneous rocks of the region
Michelle_847	Laramide folding and thrusting/deformation was responsible for the intial tilting of the Permian through the Cretaceous strat prior to basin and range modification.
