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.

Primary stratabound mineralization of the Eureka mine occurs within the Buntsandstein redbeds.
Michelle_524
Secondary mineralization of the Eureka mine occurs in small veins, fractures and joints.
Michelle_525
The third stage of mineralization of the Eureka mine is due to supergene processes. Natural pseudomorphic replacement of primary ores result in a wide variety of secondary minerals, especially uranium minerals.
Michelle_526
Recent post-mining mineralization on tunnel walls of the Eureka mine are considered Anthropogenic. They occur as crusts, coatings and cryptocrystalline efflorescences.
Stage 2 of 4. Tectonic activities of the Pyrenean orogeny allowed the remobilization of chemical species. Small veins, faults and joints were mineralized with quartz, ankerite and some sulfur minerals.
Stage 3 of 4. Supergene process resulting in natural pseudomorphic replacement of primary ores. This allowed extensive secondary oxidized minerals including sulfates, arsenates, phosphates, vanadates or selenates. Many of the oxidized minerals contain U.
Stage 4 of 4. Supergene process resulting in anthropogenic mineralization. Post mining, secondary mineralization occurring as encrustations, coatings and cryptocrystalline efflorescences.
