A Note on the Uranium Occurrences and Probable Controls for Mineralisation in Upper Gondwana Sequence of Kharatoria Area, Chhindwara District, Madhya Pradesh

摘要

Significant uranium mineralisation associated with subfcldspathic arenite of Lower Denwa Formation (Mid. Triassic) has been located at Kharatoria, dist. Chhindwara, M.P. in Satpura Gondwana Basin. Grab samples collected from the radioactive horizon analysed up to 0.1 %U_3O_8 with <0.005%ThO_2. Besides, a spring sediment sample collected from the same locality indicated anomalous concentration of U, Zn, Pb and Ce and Th. Preliminary studies revealed the possibility of sedimentary fades/ hydrothermal control of uranium mineralisation and probable presence of organic/inorganic carbon induced reducing environment in the area.
