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_000851	Whewellite is found associated with rodent coprolites in Rancho Guadalupe cave. The cave is in Cretaceous limestone, enriched by thermal fluids and organic material. Bird guano, vegetal detritus, and rodent excreta contribute to diverse biomineralization.
Michelle_000852	Cretaceous carbonate platform environment, now a karst environment
Michelle_0023	Cave in formation
