Abstract This paper aims to study the geochemical characteristics of shale of Disang group of Eocene age. Geochemical study and the data reported indicate that Shales are deposited under the marine condition. Tectonic setting was active continental margin to passive continental margin and sediments were derived from volcanic andor granitic source area. Study reveals that Source-rating of studied shale is found to be poor and its hydrocarbon source proclivity towards gas. Further shale of the Disang group is found to contain over-matured organic matters represented by Kerogen Type-III and Type-IV.
