(Uraninite) and secondary mierals such as tyuyamunite, carnotite are commonly existed and enriched by water at places in cavities in Vihowa Group (Oligocene Chittarwata, Vihowa, Litra and Chaudhwanan formations) and may be hosted in coal and sandstone bearings formations.
It is also reported from the Lady Stith claim, associated with kaolinite, gypsum, fluorite, and tyuyamunite (Nelson-Moore et al., 1978; Thompson, 1992).
