Mount Homa

Homa Mountain is a large carbonatitic complex with a flat-topped summit that forms a broad peninsula on the E shore of Lake Victoria. This dominantly Miocene-to-Pleistocene complex contains numerous flank vents, including the carbonatitic and ultramafic Lake Simbi maar on the lower E flank. The Chiewo, Got Ojawa, and Got Oloo vents on the S and W sides of Homa Mountain were formed during the latest stage of carbonatitic activity. Legends of inhabitants near the Lake Simbi maar suggest that it may have been formed in historical time.
