“…The maximum thickness of this formation is about 200 m (Carter et al, 1963;Arabi et al, 2009). While Zaborski (1998) suggested a thickness of 300 m for the Kerri-Kerri formation, Abubakar et al (2010) suggested a thickness of about 320 m for the formation. The Gombe Formation is composed of sandstones, silt stones, and ironstones of Maastrichtian age.…”

“…Benkhelil et al (1989) suggested that the evolution of the trough could be a result of tension resulting in a rift or wrench-related fault basin. Mesozoic to Cenozoic magmatism accompanied the evolution of the tectonic rift as it is scattered all over and throughout in the trough (Coulon et al, 1996;Abubakar et al, 2010). The stratigraphy of the study area consists of alluvium, the Kerri-Kerri Formation, the Gombe Formation, the Pindiga Formation, the Yolde Formation, the Bima Formation, and basement rocks as the oldest (Figure 3).…”

“…The stratigraphy of our study area consists of the alluvium, the Kerri-Kerri Formation, the Gombe Sandstone Formation, the Pindiga Formation, the Yolde Formation, the Bima Formation, and basement rocks as the oldest. m) consists mainly of shale mudstone with intercalations of limestone occurring in some areas (Abubakar et al, 2010). The Yolde Formation is believed to have a thickness of about 200 m and it is a transitional sequence between the continental Bima group and the marine deposits of the lower part of the Pindiga Formation.…”

“…The Chad Basin developed at the intersection of many rifts, mainly in an extension of the Benue Trough (Nwankwo et al, 2009). Nine aeromagnetic maps were analyzed to determine some characteristics of a prominent aeromagnetic anomaly within the Gongola Basin in the Upper Benue Trough, northeastern Nigeria, by Abubakar et al (2010). They assumed three magnetic layers in the area and computed average depth values of 1.25 km, 4.03 km, and 5.39 km for the layers, respectively.…”

The Wikki Warm Spring (WWS) is located on the Kerri-Kerri formation of tertiary age. This forms part of the Benue Basin, which links up with the Chad Basin in the north and extends southwest to the Anambra Basin in Nigeria. The stratigraphy of the WWS region consists of alluvium, the Kerri-Kerri formation, the Gombe formation, the Pindiga formation, the Yolde formation, the Bima formation, and basement rocks as the oldest. We estimate the depth to the bottom of magnetic sources (DBMS) in the WWS region using the fractal sources distribution approach on aeromagnetic data to identify the geothermal system of the WWS region. The adopted computational method is based on statistical methods of depth determination from the radial power spectrum assuming a fractal distribution of magnetic sources. The average estimated DBMS at the WWS source location is 10.72 ± 0.54 km. The obtained results imply an average thermal gradient of 54.11 °C km -1 and heat flow value of 135.28 mW/m 2 . Generally, shallow DBMS values are obtained in the northeastern region of the WWS area and these increase towards the southwestern region when regional variation patterns of estimated depths are considered. The generally shallow DBMS obtained in the study area is attributed to magmatic intrusion or diapirism in the subsurface and emphasizes the effects of large-scale tectonic events, particularly the basin-initiating event, as major influences on the thermal history. Results will contribute to decisions on where to drill boreholes for further geothermal energy exploration in the region.

Regional estimation of Curie-point depth (CPD), subsurface heat ow and geothermal gradients variations in the Shelleng area and environs of northeastern Nigeria was carried out in this study using spectral analysis of high-resolution aeromagnetic (HRAM) data. The HRAM data were divided into nine (9) overlapping blocks and each of the blocks was analyzed to obtain the 2D radially averaged power spectrum which enabled the computation of depths to the top and centroid of magnetic sources. The obtained values were then used to determine the depth to the bottom of magnetic bodies or the CPD, geothermal gradients and crustal heat ow changes in the study area. Results showed that CPD varies from 7.56 to 18.01 km, with an average of 11.72 km; geothermal gradient values vary between 32.20 and 76.72°C/km, with an average of 52.76°C/km, while heat ow variations range from 80.51 to 191.80 mW/m 2 , with an average of 131.85 mW/m 2 . Shallow CPD zones identi ed in the northeastern, western and southwestern portions of the study area correspond to zones of high geothermal gradient values and high subsurface heat ow distributions. These areas signify zones associated with anomalous subsurface thermal conditions and were therefore recommended for further detailed geothermal energy exploration studies.
