BackgroundHoma Mountain is a large carbonatitic complex that forms a broad peninsula on the eastern shore of Lake Victoria. The 1751-m-high flat-topped summit of the volcano rises about 600 m above the lake. This dominantly Miocene-to-Pleistocene volcanic complex contains numerous flank vents, including the carbonatitic and ultramafic Lake Simbi maar on the lower east flank. The Chiewo, Got Ojawa, and Got Oloo vents on the southern and western 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.
