Quick Summary

The Voltaian Basin is a geographical region primarily located in north-central Ghana. It is characterized by a large area of Paleozoic sediments, forming a basin where elevations rarely exceed 500 feet. This basin is dominated by Lake Volta, an artificial lake created by the Akosombo Dam on the Volta River. The Black Volta, Red Volta, and White Volta rivers, which originate in Burkina Faso, converge in Ghana to form the Volta River. The edges of the basin rise into plateaus, bordered by scarps like the Kwahu Scarp in the south and the Gambaga Scarp in the north.1234
