Abstract

The paper reports for the first time uranium mineralisation associated with phosphatic tuffaceous shale of the Lower Vindhyan Semri Group, near the southern margin of Son Valley around Mankisar-Karaundiya-Kathar area. Grab samples from this rock unit analyzed upto 900 ppm of U₃O₈ and upto 18.5 % of P₂O₅. Uranium enrichment in tuffaceous shale has been inferred due to hydrothermal activity.

Keywords
