The mine is located in a thrust zone which forms a part of the northern Precambrian shield of India. Temperature observations were taken at nine different levels from 356 to 848 meters below the surface. The least-squares gradient for temperature in the mine is 19.37±0.74 °C/km. Thermal conductivities in the vertical direction were determined for twelve representative samples of schists and five samples of soda granites, using a divided-bar apparatus. The mean values for thermal conductivity of schists in directions parallel and perpendicular to the plane of the foliation are 8.28±0.98 and 7.22±0.86 mcal/cm sec °C, respectively. The mean conductivity in the vertical direction is 7.66±0.56 for the schists, 7.18±0.48 for five samples of granites, and 7.52±0.58 for both schists and granites. The heat flow is 1.45±0.12 μcal/cm2 sec. This value is much higher than the previously reported value of heat flow in the Kolar gold field on the southern Precambrian shield of India. It is also higher than most other values reported for Precambrian shields of the world. References Beck, A.
