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 Name:
Khmara Bay, Casey Bay, Napier Complex, Enderby Land, Eastern Antarctica, Antarctica

Oldest recorded age at locality: 2485
Youngest recorded age at locality: 2448
