Some Geothermal parameters of Lamurde and environs are determined by integrating spectral analysis, Euler deconvolution and Source parameter images. High resolution aeromagnetic and satellite gravity are analyzed using the integrated techniques. The spectral analysis revealed the curie point depth (CPD) ranged of 7.21km to 11.74km with an average of 8.92km, the heat flow varied from 123.51 to 201.00 and the geothermal gradient that ranges between 49.40 to 73.44 . The average geothermal gradient of 65.96 is far greater than accepted standard value for geothermal potentiality. The depth to magnetic source as determined by source parameter imaging, ranged from 142.69km to 32329.50km while the bouguer anomaly depth ranges between 94.29km to 2033.34km. Geologically, the structural index of zero ranges between - 366.16m for outcropping magnetic anomalies bodies to 3563.80m deep lying magnetic bodies and -691.47m bouguer anomalies (shallow bodies) to3851.69m bouguer anomalies (deep lying bodies) as obtained from standard Euler depths deconvolution. These characteristics revealed from integrating above methods in these study areas and the location of Lamurde hot springs are indication that there might be good sources of geothermal energy for exploration and exploitation.
