Heat flow density (HFD) studies have been carried out in four boreholes (ranging in depth from 100 to 725 m) spread over Sohagpur and Raniganj Gond-wana basin (India). Thermal conductivities have been measured for about 136 core specimens using divided bar method. Estimated mean HFD of the areas are found to be higher than the mean HFD of the Precambrian shield area of India. The higher HFD could mostly be attributable to the heat generation of the Precambrian base-ment and crustal geothermal provinces of the areas.
