Geology
editKarshi which is part of the Basement Complex of North central Nigeria is located within the South Eastern part of Abuja. It is almost predominantly underlain by high grade metamorphism and igneous rocks of Precambrian age (600±50million years) generally trending SSW, these rocks consists of gneiss, migmatites, granites and schist belt outcrops along the western (Kupayi) margin of the area, the belt broadens North wards and attains a maximum development in the area, with little concentration of placer gold deposit. Granites mostly occupy the South eastern part of the area (Kurape Hill) while gneiss and migmatites dominate inside town (Rocks behind primary and secondary schools). Most of the rocks are intruded by pegmatite. The topography of Karshi is rugged and their relief is high. In general the rocks are highly sheared. Karshi is endowed with various industrial minerals of economic importance use for building and construction such as gneiss, granite, schist, laterite, sand and gravels.
