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 IDLocality Notes
Michelle_511Jomac Mine occurs in the Triassic Shinarump Formation containing uranium ores, organic material and clays. It is the TL for oswaldpeetersite, with the mineral occurring within a siltstone bedding plane.
Michelle_744The Triassic Shinarump member of the Chinle formation hosts the Blue Lizard Mine and other significant uranium deposits in the White Canyon District.
Michelle_745Ore minerals were deposited as replacement of wood and other organic material and as disseminations in the enclosing sandstone found in paleochannels.
