Gauthierite
The matrix of the type material is quartz with disseminated altered uraninite. The mineral may form by weathering of uraninite in the presence of radiogenic lead, while potassium may be leached from other gangue materials.

Clarkeite
Clarkeite forms by oxidation and replacement of uraninite late during pegmatite crystallization. Although uraninite-bearing granite pegmatites are common, clarkeite is rare and occurs intimately intergrown with other uranium minerals.

Uranium mining in Wyoming
The principal ore minerals are uraninite, coffinite, metatyuyamunite, and carnotite. Most uranium deposits are in the Wasatch, with ore zones containing uraninite and pyrite.

Gummite
Gummite is a yellow amorphous mixture of uranium minerals, oxides, silicates, and hydrates of uranium, derived from the alteration of uraninite.

Zippeite
Mining began in 1859 not only for the products which resulted from uraninite's decomposition, but for uraninite itself.
