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_540	The Biraya deposit is comprised of a sequence of lens-shaped carbonatite bodies accompanied by fenites of the Biraya dike. The fenites developed at the expense of Precambrian gneisses, and schists are crosscut by Permian granitoids. These sequences represent the Eastern margin of the North Baikal Highlands.
