“…The findings reveal distinct variations in these properties among different rock types. Intrusive rocks generally exhibit high resistivity values [35][36][37] . Notably, the Middle Ordovician diorite shows a wide resistivity range from 436.3 to 20533.5 Ω.m.…”

Geophysical exploration techniques are crucial in facilitating accurate mineral prospecting predictions, but relying solely on single methods can introduce uncertainties. In this study, we employed audio-frequency magnetotelluric (AMT) methods, complemented by gravimetric surveying and high-resolution magnetic profiling in the Yongxin gold deposit. Utilizing advanced three-dimensional modeling techniques, we were able to precisely delineate the lithological variations and deep-seated mineralization features inherent to the area. The inversion and interpretation of cross-sectional AMT data illuminated the subsurface structure down to a depth of 1.5 kilometers. This enhanced data reliability was achieved through an integrated interpretation constrained by gravity, magnetic, and electrical datasets, thereby enabling a more accurate inference of the deeper geological framework. Furthermore, by amalgamating regional geological data, drilling information, and additional datasets, we uncovered the characteristics of deep mineralization, the three-dimensional configuration of mineralization-related rock masses, and the spatial orientation of known ore deposits. This approach facilitated a transparent visualization of the deeper geological formations. A thorough analysis was conducted on the distribution patterns of ore-controlling structures and exploration markers. Consequently, we have established a geological-geophysical model tailored for mineral exploration within the study area, which provides an effective reference for future deep exploration work.

“…There is equally another compelling reason for the exploration efforts in the Sokoto Basin (Adamu & Likkason, 2022;Adamu et al, 2021;Kogbe, 1972Kogbe, , 1979Kogbe, , 1981Obaje et al, 2009Obaje et al, , 2020. Potential field gravity method has proved very effective for providing useful information known to guide various exploration campaigns, be it regional studies (Olawale et al, 2020;Moumoni et al, 2016;Zahra & Oweis, 2016), economic mineral or oil and gas exploration (Ugbor et al, 2020). In defining basin's tectonic framework from Gwandu formation in the southeastern part of Sokoto basin for delineation of outlining favourable region for hydrocarbon prospect, an important reconnaissance mapping of structural features has been generated by the analyses of satellite gravity data.…”

Presently a digitized composite satellite gravity data covering the Gwandu formation in Sokoto Basin were acquired and processed with a view to interpret the Bouguer anomalies as well to equally image the upper lithospheric structures beneath the Study area and its environs. The research work was aim to study the structural settings of crustal movement in the Gwandu formation. A least-square fitting polynomial surface of a third-degree order was applied in separating regional and residual gravity components from the Bouguer anomaly. The attributed low gravity sedimentary infill from the residual anomalies were tectonically trends NE -to- SW about the vicinities of Tambuwal, Goronyo, Gada and Argungu, Kolmalo and about Yauri, Koko and Jega, Kamba as well as Bagudo. Data enhancement techniques such as first vertical derivative, total horizontal derivative (THDR), analytic signal, spectral depth analysis, and the standard Euler deconvolution (SED) were applied to enhance deep-seated structures. Results from the Spectral Analysis revealed that the average thickness of the sediments varies from 1.679 km to 4.181 km, outsized enough for hydrocarbon prospect. The derivative maps revealed parallel to sub-parallel trending NW –to- SE, E -to- W fracture zones within the sedimentary infill underlying the study area, coinciding with the cretaceous zones. Hence, the identified lineaments (faults or lithologic contacts) and structures in the area can be attributed to the tectonic setting of the area and probable migratory routes for hydrocarbon migration. More detailed ground gravity and seismic studies may lead to discoveries of structural or stratigraphic traps.
