摘要:This paper is aimed to assess the geophysical structural associated with gold mineralization in the study area. This was achieved by determining depth to basement complex of the study area, producing a magnetization map showing magnetic susceptibility range across the entire study area, and produces a geological map of the study area. The study area falls within the basement complex of northwestern Nigeria and covers four adjacent quarter degree sheets of Danko, Fokku, Shanga and Wudil. Artisanal miners often suffer a lot in finding the gold occurrence in the area which results to the destruction in landforms and the environmental setup. The artisanal miners are exposed to digging with hardship for them to determine the structures associated with gold mineralization. Previous works have shown that primary gold mineralization within the Nigerian basement complex is controlled by geologic structures where they act as conduits for fluids flow and as loci for mineralization. The anomalies on the aeromagnetic map were defined by fitting a first order polynomial to the total fields, by the method of least squares to obtain the residual field data. First vertical derivative and analytic signal computed, defined distinct pattern of the magnetic signatures. Depths to the surface of the geologic structures were obtained from Euler deconvolution solutions which give an average depths range of 167.9 m (0.1679 km) to 2526.7 m (2.5267 km).With very few solutions having depths so Izga fault can be used for gold mining.
