Abstract
Abstract The Precambrian Champaner Group of rocks are intruded by Godhra granites in Jambughoda area. Significant uranium mineralisation has been located in the fractures in the dolomitic limestone of Lower Champaners with uraninite occurring as the primary uranium mineral. The geochemical features observed for the granites suggest that the granite melt, originated by the partial melting of relatively silicic crust, was further modified by fractionation processes during which uranium was concentrated in the late magmatic and subsequent hydrothermal fluids. The Champaner deformation resulted in the formation of WNW-ESE regional fracture system and crush zones, thus making the rocks highly penneable for the passage of uranium-rich hydrothermal fluids and offering open spaces for precipitation of uranium under suitable physicochemical conditions.
