Assessment of Groundwater and Mineralization Potentials of Jada and Environs Northeastern Nigeria Using High-resolution Aeromagnetic Data

Abstract

This study analyzes high-resolution aeromagnetic data over Jada and its environs to evaluate groundwater and mineralization potentials. The research was conducted in three stages: data acquisition, analysis, and interpretation. Regional-Residual Separation (RRS) was employed to extract residual data, which was further processed using spectral analysis to determine Depth to Magnetic Sources (DMS) and analytic signal (AS) methods to delineate lineaments (L). The results indicate that the susceptibility values of the Total Magnetic Intensity (TMI), and Residual Magnetic Intensity (RMI) maps range from -35.3 to 173.7 nT, and -3.0 to 151.0 nT, respectively. The depths of deeper magnetic sources (D1) vary from 0.530 to 1.960 km, while shallow magnetic sources (D2) range from 0.423 to 0.622 km. The analytic signal map (ASM) exhibits values from 0.008 to 0.178 nT, while the lineament density map (LDM) ranges from 0.52 to 4.71. Structural trends derived from the anomalies and lineaments indicate multiple tectonic cycles have shaped the area, with predominant lineament orientations in the NE-SW direction. The findings suggest that the region holds promising potential for mineralization and groundwater accumulation.
