Description
Fine, shiny black crystals of brannerite, a uranium-rich titanium oxide, in a gray quartz gangue. Brannerite is often associated with native gold in many deposits, or at least is an indicator of the presence of gold nearby.
Brannerite from the Bou Azzer mines in Morocco.
Mineral of the collection of the naturalist merchant Deyrolle, of Paris, provided with box and label of origin (XIXth century).
