Description/Abstract | The western continental margin of India can be classed as a divergent or passive margin.^The western continental shelf is an extensive carbonate bank (Bombay offshore basin) passing into clastic sediments on the north and south.^Three craton-margin embayed basins-Kutch, Cambay, and Narmada- in the northern part of the shelf, are filled predominantly with clastic sediments.^These basins occupy grabens bounded by faults diverging seaward.^The grabens were formed by three rift systems along major Precambrian tectonic trends.^The rifting developed sequentially from north to south around the Saurashtra horst.^Kutch basin was formed in the Early Jurassic, followed by Cambay basin in Early Cretaceous time, and the Narmada in the Late Cretaceous.^It appears that these rifting events occurred at successive stages during the northward migration of the Indian plate after its break from Gondwanaland in Late Triassic or Early Jurassic.^It is inferred that these rift basins opened up successively as a result of the counterclockwise drift of the Indian craton.^Bombay offshore and Cambay are two major oil-producing basins in the western margin.^These basins are characterized by high geothermal gradients attributed to the shallowness of the mantle in this region.^Oil has not been found in KUtch basin, which is mainly an onshore Mesozoic basin.^The basin basin depocenter shifted offshore at the northwestern part of the continental shelf where the shelf is wide. |
