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.

Age can refer to the age of a specific nickel sulfide deposit, or the general age of the metallogenic province containing nickel deposits that are similar to a dated deposit (e.g. 2705 Ma Komatiite-hosted deposits in the Eastern Goldfields Province). Dates on felsic volcanic rocks that include komatiites are consistent with an inferred eruption age for these komatiites of c. 2705 Ma.
