Abstract

Uranium mineralisation as Uraninite vein filling is seen in joints and fractures in the quartzites exposed within an eroded cover of crystallines, tectonically thrust from east and NE in Kulu-Banjar area of Himachal Pradesh. Analysis of the joints suggests a tensional origin and can be related to the three main folding events identified from the fold structure in the quartzites. It is believed that the mineralisation is essentially under low temperature-pressure conditions as there is a remarkable absence of large scale wallrock alteration.

U-Pb dating of six Uraninite samples reveals two distinct episodes of mineralisation at 1200 m.y. and 700 m.y. confirming the Precambrian age of Uranium mineralisation, and associated metasediments.
