Abstract

Deep Seismic Sounding (DSS) studies were started in India in 1972, but till date no attempt has been made to synthesize the data to provide a bird's eye view of the variation in crustal model. Present synthesis of seismic data provides a glimpse of change in the regional velocity scenario as well as basement and Moho depth configurations in selected parts of the Indian crust. In the sedimentary basins of east-coast, Bengal and Cambay, the basement depth varies between 2 and 10 km, and the Proterozoic Vindhyan and Cuddapah basins show maximum depths of 5 and 10 km respectively. The maximum Moho depth is indicated as 42-44 km in the central Indian region.
