A 3 Axis MCL6 Magnetometer was used to gather the magnetic data. The information was gathered from a 1 km by 500 m area along eight profile lines with a length of roughly 1000 m each. Each profile is spaced roughly 250m apart from the other. The magnetic investigation was created in a way that provided clear definition of the depth to phenomena in the region. Measurements of the magnetic strengths at discrete spots along traverses spaced consistently throughout the area of interest were required by the data collecting approach in order to sufficiently cover the segment utilized to ascertain the structure and deformation analysis of the study area. The geological conditions in the shallow subsurface provide the highest frequency events of interest, whereas magnetic property contrasts at or beneath the basement surface produce the lowest frequency occurrences. Significant lateral variations and contrasts in the shallow formations’ magnetic characteristics are produced either singly or as a result of a particular combination of faulting, deposition, and mineralization linked to displacement and deformation of the structural system.
