The Geology of Part of Paiko Sheet 185 (North West), Nigeria

The mapped area which is located between latitude 6°36'N—6°42'N and longitude 9°26'E—9°30'E on the Paiko sheet 185 North—west covers and approximate area of 80km2 in Paikoro Local Government Area of Niger State. The mapped area covered in this project is composed of granites of the older granites suite of the Nigerian Basement complex which can be distinguished into; leucocratic granite which is the most extensive and covers about 50% of the total area. Biotite granite which forms 35—40% and is the second largest outcrop of rocks in the mapped area which are mostly abundant in the western portion and finally gramodiorite which makes up 10% of the total area is found in the North—Central portion of the mapped area. The textures of the various granitic rocks varies from medium to coarse grained textures.
