Mount Homa

Homa Mountain

複成火山 · Kenya · 1751m

The Homa Mountain volcanic complex rises beyond an archaeological site north of the volcano in which Miocene-Pliocene hominins were excavated. Homa Mountain is a dominantly Miocene-to-Pleistocene carbonatitic complex that forms a broad peninsula on the eastern shore of Lake Victoria. Numerous flank vents include the carbonatitic and ultramafic Lake Simbi maar on the lower east flank. Oral history of inhabitants near this maar suggest that it may have been formed in historical time.

地質学的概要

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.
