Description
In this present study, an exploration and interpretation rare pegmatite using high resolution magnetic data and satellite imagery of the area under study is done. The methodology adopted here was primary data approach in which the major structural trends of the area were mapped. The lineaments extracted from the magnetic data range in length from 78.56m to about 1213m. Most of the lineaments extracted from the area were subsurface within the quartz-mica and migmatites while some of them have surface expressions even though not clearly defined. These magnetic lineaments could be the contacts between two rock types of contrasting magnetic susceptibility or edges of structures that could be faults or intrusives within the sediments. These faults may be host to pegmatites or quartz veins that were mineralized. Magnetic lows can also mark non-magnetic, possibly mineralized shear zones or alteration zones. Most of the magnetic lineaments are within a depth of a few meters to 150 meters maximum. It is recommended that further exploration work which will include but not limited to production of mineral potential map and delineating mineralization concentration spots should be done by the relevant agencies.
