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
Giersdorf_00000216	Model derived primarily from studies conducted in the Mount Tom Price mine but with supplemental information acquired from the Channar and Mount Whaleback
Michelle_510	Deposit occurs in Archean serpentinized peridotite. It is the TL for three carbon minerals, paraotwayite, otwayite, and nullaginite, that occur as secondary mineralization in shear zones of the deposit. The veinlets cut all other minerals and appear to be late stage and low temperature in origin.
Michelle_512	Deposit occurs in Archean serpentinized peridotite. The serpentinite has undergone extensive alteration by shearing and silicification. Otway deposit is the TL for three carbon minerals, paraotwayite, otwayite, and nullaginite, that occur as secondary mineralization in shear zones of the deposit. The veinlets cut all other minerals and appear to be late stage and low temperature in origin.
