Abstract
At Belka Pahar, in the Sirohi district of Rajasthan, metasediments of the Delhi Super Group are associated with a medium-grained, leucocratic, alkali granite. Whole rock isotopic data for this granite define a Rb-Sr isochron corresponding to an age of 860±25 Ma and an initial 87Sr/86Sr ratio of 0.7059 ±0.0032.
