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.

Giersdorf_00000992	Uranium mineralization is hosted by the Chinle Formation in the Monument Valley district. The major deposits are particularly found within the Shinarump Member of the Chinle Formation. Uranium deposits are commonly localised at confluences and intersections of channels and/or near bends. This is interpreted to be caused by stronger currents able to cut deep scours in the basement.
