“…1). The trough is filled with sediment whose ages range from middle Albian to Maestrichtian and whose thickness generally decreases from the lower and middle Benue to the upper Benue region (Charles, 1985;Abraham et al, 2019;Ayuba and Ahmed, 2019). The basement complex within the study area includes; The Migmatites -Gneiss Complex which is generally considered as the basement complex (Rahaman, 1988), and it is the most widespread of the component units in the Nigerian basement.…”

This work is aimed to determine the depth to basement of some magnetic sources in the study area. Four aeromagnetic sheets were acquired from the Nigerian Geological Survey Agency which includes (Bajoga, 131, Gulani, 132, Gombe, 152 and Wuyo, 153). The study area covers an estimated area of about 12100km2 between latitude 90N-110N and longitude 110E-130E. The total magnetic field of the study area have been evaluated. In order to determine the basement depth, spectral analysis technique was applied. Detailed analysis of the aeromagnetic data for the study area was performed. The procedure involved in the analysis include reduction to equator to remove the effect of inclination, contouring of the total magnetic intensity, separation of the regional and residual anomalies using polynomial fitting of first order, qualitative interpretation and quantitative interpretation. The residual field of the study area composes of low magnetic anomalies reaching a minimum value of -158.6nT as observed in the northern and southern parts and high magnetic anomalies reaching a maximum value of 178.1nT as observed in the western part of the study area. The result from the spectral analysis for each block shows that the depths to the magnetic source are 5.20Km for block 1, 5.74Km for block 2, 7.59Km for block 3 and 3.56Km for block 4. The average depth to magnetic source in the study area was found to be 5.52Km. Based on the computed average sedimentary thickness obtained in this study area, hydrocarbon accumulation in the study area is feasible.

“…Integration of aeromagnetic and aerogravity data in the southeastern part of Nigeria showed that the Curie point depth, crustal thickness and the geologic features of the environment are in support of the geothermal energy resource (Abraham et al 2019). A range of 9.8 to 19.3 km was obtained as the Curie point depth, 26.5 to 35.8 km was obtained as the crustal thickness (depth to Moho), 29.0 to 45.0 °Ckm -1 as the geothermal gradient and 52.2 to 101.5 mWm -2 , being the subsurface heat flow of the SE Nigeria.…”

There is quite a long history in Nigeria of Geothermal energy exploration. Geothermal energy resources are available in every part of Nigeria beneath the subsurface. The resources, however, vary in concentration in all the geological parts of the country. This paper reviewed the prospects of geothermal energy exploration by using the potential field (magnetic and gravity) technique for the exploration activities. The potential field data is capable to provide information on the subsurface structures after some filtering techniques (in case of magnetic) or data corrections (in case of gravity) have been applied to the raw field data. The processed data is capable to scan the lateral and vertical extent of anomalous zones beneath the surface. Geothermal energy, if properly exploited would contribute to the generation of clean energy in Nigeria for domestic and industrial purpose.

“…In this investigation, Magsat satellite-generated magnetic data flown by NASA were used to offer insights into the subsurface geothermal anomalies [36]. The data that have the potential to probe different rock properties were applied to locate and determine the trend of geothermal systems and structures within the KSA.…”

In this paper, certain areas of the Kingdom of Saudi Arabia (KSA) are assessed in order to map potential geothermal energy zones. To evaluate high-resolution aerial magnetic data, spectral depth analysis using a modified centroid approach was used. The calculated geothermal parameters were gridded in order to delineate the regions characterised by a shallow Curie point depth (CPD) and a high geothermal gradient (GG) as well as a high heat flow (HF). The CPD, GG and HF calculated from the analysed data varied in the ranges of 6.0–15.0 km, 40.0–100.0 °C/km and 90.0–270.0 mW/m2, respectively. The obtained results show the concurrence of the positions of shallow CPD (<8.0 km), high GG (>83.5 °C/km) and high HF (>211.0 mW/m2). The geothermal systems that are oriented in the E–W direction are related to the Red Sea tectonics, the tectonic opening of the Red Sea/Gulf of the Suez Rift, hot subterranean anomalies and high enthalpy from radioactive granites. Likewise, the geologic structures (fractures and faults) related to the Red Sea tectonics serve as channels for the movement of hydrothermal fluids and the deposition of associated minerals. All in all, another geophysical study involving deep boreholes, and seismic, magnetotelluric, electromagnetic and geochemical data should be conducted to evaluate and estimate precisely the economic reserves of geothermal resources.
