Abstract: The strong association between uranium and carbonaceous matter, more so in sandstone type uranium deposits world over is well known. In India, sandstone type uranium deposits are mainly located in Meghalaya. Wahkut and Umthongkut constitute two prominent areas in Meghalaya Plateau hosting sandstone type U-mineralization in Lower Mahadek Sandstone of Cretaceous age. In order to evaluate the contribution of carbonaceous matter in U-mineralization in these areas, core samples of Lower Mahadek Sandstone were studied in terms of Total Carbon (TC), Total Organic Carbon (TOC) to understand the relation between uranium mineralization and carbonaceous matter. The carbonaceous matter samples were also taken up for Carbon-Hydrogen-Nitrogen- Oxygen analysis (CHNO) and Functional Group specification by Fourier Transmitted Infrared Spectrometer to decipher the nature of carbonaceous matter that helped in fixation of uranium.
