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.

This collision-related magmatism took place when Indian plate collided with the Eurasian plate ~55 to 50 Ma ago (e.g., Molnar and Tapponnier 1975; Petterson and Windley 1985; Beck et al. 1995; Rowley 1996; Bignold and Treloar 2003; Rehman et al. 2011)
