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.

(2014) BOOK_CPFV3_2014Age of secondary mineralization resulting from self-ignition. Anna mine was the largest producing coal mine in the region. Waste from the nearby coke furnaces was dumped over the mine tailings and spread over three dumps, Anna I, Anna II and Anna-Noppenberg. Both Anna I and II self ignited, likely burning extensively due to the high amount of residual coal in the waste. Se, Hg are introduced with the alteration.
