Abstract

Non-invasive geophysical methods (aeromagnetic and aeroradiometric methods) have been employed to investigate the subsurface of Northwestern Rijau in the northernwestern part of Nigeria with the aim of addressing the need for a structural map that could guide in-situ gold exploration activities in the area. The aeromagnetic data was processed to enhance the signal-to-noise ratio of the data and subjected to source edge detection techniques for structural interpretation. The aeroradiometric data were used to produce ternary image and potassium-to-thorium ratio map for detection of potential alteration zones associated with gold mineralization. The structural map derived showed predominantly trending NE-SW geological structures and indicates polyphase crustal deformations in the study area. The result also showed high prospectivity zones for gold exploration. These zones are intersected by geological structures, indicating structurally controlled mineralisation and suggesting the likelihood of gold depositions along or near these structural features. Nearly all the known gold occurrence locations in the study area coincides with the interpreted prospective zones, validating the significance of non-invasive geophysical methods in mineral exploration. The geological structures in the identified high prospectivity zones were recommended as targets for in-situ investigations and other gold propecting activities in the study area.
