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_709	Mellite is formed from the reaction between organic carbon rich solutions with aluminosilicates. It is found but rarely in nature, occurring as crystalline prisms or pyramids with a resinous lustre as a secondary mineral in crevices in brown coal and lignite and sometime in association with gypsum in lignitic clays in Bohemia, Thuringia and Russia. At Artern, mellite is found in lignite and coaly slates.
