Abstract
Interpretation of High Resolution of Aeromagnetic Data over Numan and its environs was carried out to determine depth to the centroid (Zo)km, depth to the top boundaries, Curie Point Depth geothermal gradient (dt/dz) 0C/km and heat flow (q) mW/m2 of the area under study. High Resolution of Aeromagnetic Data with sheet number 173,174,175, 194,195 and 196 of Kaltungo, Guyuk, Shelleng, Lau, Dong and Numan respectively. Aeromagnetic data were divided into six blocks and subjected to spectral analysis via the Oasis Montaj Software with upward continuation techniques to get the magnetic anomalies over the area. The following parameters were estimated; Depth to the centroid (Zo) which vary from 12.5km to 16.4km , Depth to the top boundary (Zt) range from 7.01km to 9.65km, Curie Point Depth (Zb) vary from 17.99km to 25.99km, Geothermal Gradient (dt/dz) range from 22.320C/km to 32.24km and Heat flow (q) vary from 55.80mW/m2 to 80.60m/Wm2. The estimated average value of Depth to the centroid (Zo), Depth to the top boundary (Zt), Curie Point Depth (Zb), Geothermal Gradient (dt/dz) and Heat flow (q) were 15.03km, 8.35km, 21.71km, 27.010C/km and 67.54m/Wm2 respectively. There is possibility of geothermal energy exploitation and exploration around Guyuk since it has the highest heat flow of 80.60m/Wm2 and the Curie Point Depth (CPD) of 17.99km. For further research there should be application of integrated geophysical techniques in order to locate more potential zones for geothermal energy exploitation and exploration within the study area.
