The organic carbon and hydrocarbon potential have long been considered as two most important organic geochemical signatures in the assessment of the source rocks in sedimentary basins. In this paper, a new method is introduced to estimate original organic carbon in the marine argillaceous source rocks according to Mo-TOC correlation exemplified by the Cretaceous marine mudstones and shales in southern Tibet. If this method is viable, it will contribute a lot to the assessment and prediction of oil and gas resources in the high-maturity and overmature source rocks in China.
