Ore minerals are coffinite, uraninite, and uranium-bearing apatite. Primary ore minerals are uraninite and coffinite. It is commonly associated with zircon, monazite, gadolinite, fergusonite, uraninite, yttrialite and pyrochlore. The uraninite here was conglomerated with garnet. The uranium ore minerals include uraninite and coffinite. The mineral was formed there as an alteration of uraninite and other uranium bearing minerals. Primary minerals include chalcopyrite, bornite, bournonite, pyrite, and uraninite. Uranium occurs as uraninite and autunite in shear zones in granodiorite. Most uranium deposits are in the Wasatch, with ore zones containing uraninite and pyrite. Permian volcanic activity formed the uraninite mineralization. The uranium is contained in autunite, uraninite, and coffinite, with gangue minerals pyrite and marcasite. Uraninite, a source of uranium, is found here, too. Ore consists of uraninite with lesser brannerite and thucholite. The principal ore minerals are uraninite, coffinite, metatyuyamunite, and carnotite. Uraninite crystals from 1 to 4 centimeter cubes were common.
