Abstract

The aeromagnetic data of Auchi _ (Sheet 266) was subjected to spectral analysis with the aim of accessing the geothermal potential of Azukala and environs. The surface temperature manifestation was found to be within the average of 36oC. The Curie point depth values ranges from (10.8- 17.93) km, the geothermal gadient values ranges from (32.35– 56.2) °C/km and the heat flow values ranges from (80.88- 140.5) mW/m2 .The SE region corresponding to Auchi, Avbiele, Iyerekwo and Azukala edge hosts the highest values of heat flow and geothermal gradient with corresponding shallowest values of curie point depth .Generally, for a viable geothermal reservoir, a heat flow range of 80 to 100 mW/m2is recommended, hence it can be inferred that every region on the study area could be considered as having good prospect within the regions of the study area with high heat flow above 80 – 100 mbWm-2.
