Abstract

"We report here preliminary Rb-Sr whole rock data for Archaean gneisses from the Gorur-Hassan area, South Indian Craton which yield the oldest age yet reported from the Indian subcontinent (3,35866Myr) with a very unradiogenic initial Sr/Sr ratio (0.70000.0004) which implies that the igneous precursors of these gneisses were derived from a relatively Rb-depleted source within the mantle".
