摘要：This study, is to estimate the curie point depth, heat flow and geothermal gradient using spectral analysis and empirical formula of aeromagnetic data, over Mubi and Environs, north-eastern part of Nigeria. The Aeromagnetic data was divided into equal interval of 15'' by 15’’. The results of curie point depth obtained varies between 9.48 and 10.33km, geothermal gradient varies between 21 and 24°C km-1, while the heat flow varies between 52 and 60 mWm-2. The relationship between curie depth and heat flow is an inverse linear while the geothermal gradient is proportional to the heat flow in the study area. These results are consistent with the prevailing geotectonic regime in the study area. However, this study illustrates that surface magnetic data can be used to produce Curie point depth estimate even for region with paucity of heat flow and geothermal gradient data.
