| Description |
In order to evaluate the reason for organic enrichment on the western continental slope of India, we provide Rock-Eval pyrolysis data of 25 surficial sediment samples from this area. Results show that the organic matter on the slope is hydrogenrich type 11 kerogen, which suggests that the organic carbon there is mostly marine. The low productivity of overlying waters rules out surface productivity as a possible cause of organic enrichment. The association of higher hydrogen index (Hl) values (av. 306) and higher organic carbon contents (av. 3.28 wt.%) with the sediments of the upper slope in contact with the OMZ have excellent hydrocarbon generation potential, and that these slope beds deserve preferential attention for hydrocarbon exploration
