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.

The genesis of the Bois Noirs-Limouzat uranium deposit involves a very complex history. The Bols Noirs granite resulted from the anatexis of uranium-rich sediments near granulite facies conditions. The temperature is estimated to have been at least 800 degrees Celsius accompanied by a low H20 partial pressure (possibly resulting from the presence of carbon dioxide). This magma was syntectonically emplaced along the east-west structures in a nonmetamorphic environment. Progressive crystallization and differentiation proceeded inward from the margins toward the core of the intrusion. A fluid phase formed after a large part of the magma had crystallized. This fluid migrated toward the core and altered the primary magmatic minerals, quartz, orthoclase, oligoclase, and biotite, to quartz, microcline , albite, and chlorite. The alteration of the primary accessory minerals, sphene, zircon, monazite, and xenotime, resulted in the partial liberation of their uranium content. When all the magma had crystallized, the fluid phase migrated outward to precipitate uraninite, with an associated quartz-muscovite alteration. This critical step produced an easily leachable uranium source in the granite in the form of uraninite.
