Jan 1, 1984 · Akwanga NW, Plateau State, Nigeria is underlain by pelitic to semipelitic schists which locally grade up to the sillimanite zone of regional metamorphism. Other rock types include migmatitic gneisses, small metaquartzitic bodies, augen-gneiss, granite-gneiss, granites, pegmatites and delerites.

Geological Map of the transboundary region Benin, Niger, and Nigeria. Sedimentary basins: Iullemmeden, Kandi, Sokoto.

Gross alpha and gross beta radioactivity in 40 groundwater (borehole and well water) samples from Akwanga, Wamba and N/Eggon Areas of Nasarawa North District, Nasarawa State Nigeria was measured...

The new geologic map was produced to establish the relationship between different lithological units by mapping out distinct geologic boundaries, and delineating the general structural trend of associated geologic structures on a geologic map.

The geology of Akwnaga area of northcentral Nigeria is dominated by schists, metaigneous gneisses and weakly to non-foliated granites. The Schist shows grades up to the sillimanite zone of the Barrovian type regional metamorphism and occurs as xenoliths in other rocks of the area.

Geological mapping, structural analysis and geophysical investigation were done to ascertain the different rock types and to locate areas with thick weathered zone and fractures containing groundwater.

Ninga area of Akwanga Development Area, North central Nigeria was investigated for the evaluation of groundwater potential. The area is underlain by the Basement Complex of the North-Central Nigeria.

Geological Map of Ube-Wulko area of Akwanga. Southeast Akwanga is part of the piedmont of the Jos Plateau and is relatively flat but with occasional plateaux and hills, compared to the surrounding topography. Migmatitic gneisses and schists, amphibolites, quartzites, marbles, pegmatite and dolerite dykes occur in the area in varying proportions.

Geological maps are an indispensable planning tool for any country's economic progress. The geological field mapping exercise was carried out in Oyan/Otan-Ayegbaju and environs. The entire mapped area covers latitude 8º1′N to 7º58′N, and longitude 4º47′E to 4º48′E and falls under Odo-Otin local government in Osun state, Nigeria.
