Geothermal studies were carried out at Gebel El-Maghara area at Wadi El-Safa, Wadi El-Murra, Wadi El-Rakb, and Wadi El-Massajid, where continuous temperature logs were recorded within 40 coal and groundwater exploration wells with depths ranging between 60 and 383 m. The obtained geothermal parameters are; amplitude of surface temperature (A), mean surface temperature (MST), geothermal gradient (GG), thermal conductivity (K), heat flow (Q), diffusivity (μ), and the regression coefficient (R2). Regression analysis technique was used to estimate the geothermal gradient and the regression coefficient, whereas, the thermal conductivity values of the penetrated rock units were used for estimating the heat flow and diffusivity. Results of the geothermal studies exhibited that, there are three types of geothermal gradients at Gebel El-Maghara area represented by low, normal, and high geothermal gradients with values ranging between 25 and 39 ºC/Km. The surface temperatures obtained for the study area range between 25 and 29 ºC and the heat flow values range between 54-89.7 mWm-². The formation temperatures of the top of the coal bearing horizon, upper coal seam, and the main coal seam encountered in the study area were calculated. Relatively high geothermal gradient occurs at Wadi El-Rakb according to the presence of thick coal deposits and the structure controlling the area.
