Abstract
The sedimentary patch in Konkan deepwaters, located west of the Konkan continental shelf contains over 3 km thick sediments. Based upon the interpretation of over 11,000 line km of seismic data, gross basin configuration model has been worked out. The basin floor at the base of Tertiary is differentiated into a series of rift zones containing synrift sediments. These zones are superimposed by post-rift sediments deposited as a result of flexurally distributed thermal subsidence. Therefore, the sediments in the basin are divisible into three distinct mega-seismic packages denoting three major tectonic habitats of the evolution of the Konkan continental margin. Based upon the basinal configuration of each mega-seismic package in space and time, tectono-sedimentary evolution of the continental margin is brought out with an assessment of hydrocarbon prospects.
