Interpreting the magnetic signatures and radiometric indicators within Kogi State, Nigeria for economic resources

Integrated geophysical Investigation for gold mineralization potential over southern parts of Kebbi state and its Environs, northwestern Nigeria

“…The vertical derivative of the field is intended to enhance the shallow features while attenuating the deep seated features and sharpen the shorter wavelength at the shallow subsurface region. The technique also observes the lateral variation of the susceptibility to map any sharp discontinuity within the field that could depict fracture or fault line [ 10 , 11 ]. Computing the 1VD could be angle complex due to a simple fact that the study area lies within the equator where the angle of inclination is less than 15 0 .…”

“…Several enhancement techniques can be employed to achieve the objectives of obtaining the structures associated with mineralization potential. Some of these techniques are the first vertical derivative “FVD” [ 10 , 11 ], tilt derivative “TDR” [ 12 ], horizontal gradient magnitude “HGM” [ [13] , [14] , [15] , [16] ], center for exploration targeting “CET” [ 17 ], and others. Additionally, automated techniques exist for identifying porphyry magnetic signatures and defining lineaments, which are used to pinpoint favourable ore deposit areas [ 18 , 19 ].…”
