Abstract
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.
