Cross River State is a coastal state in South South Nigeria, named after the Cross River, which passes through the state. Located in the Niger Delta, Cross River State occupies 20,156 square kilometers. It shares boundaries with Benue State to the north, Ebonyi and Abia States to the west, to the east by Cameroon Republic and to the south by Akwa-Ibom and the Atlantic Ocean. Cross River State belongs to tropical rainfall belt where rainfall is usually seasonal and at times very heavy. Humid tropical climate of about 1300 3000mm rain fall and 30°C mean annual temperatures prevail over Cross River State, except on the Obudu Plateau, where the climate is subtemperate, with temperatures of 15°C 23°C. The vegetation ranges from mangrove swamps, through rainforest, to derived savannah, and montane parkland. Just as its rocks are diverse, so also are the mineral resource potentials of the State. Covering a total of 20,156sqkm land area, Cross River State shares boundaries with Benue State to the north, Enugu and Abia States to the west, to the east by Cameroon Republic and to the south by Akwa-Ibom and the Atlantic Ocean. The Cross River, with a catchment area of 53,590 sq. km, delivers more sediment load to the coast, than the present Niger Benue drainage system. The Niger delta shoreline is therefore undergoing erosion on account of sedi ment starvation. The strength of the Cross River deltaic sedimentation derives from the Cameroun Mountain which is the most active sediment source area along the West African coast.
