Tarso Emi Chi

About

Tarso Emi Chi (tarso: "gentle mountain, high plateau", emi: "large mountain", named by the Toubou) is a volcano in Chad. Tarso Emi Chi is part of the Tibesti Mountains, a group of volcanic mountains that cover a surface area of 100,000 square kilometres (39, 000 sq mi) and reach an elevation of 3,394 metres (11, 135 ft). The mountains consist of both a Precambrian crystalline rocks and volcanic rocks. The volcano consists of a lava plateau that originated in a number of vents, which form a number of volcanic cones. It covers a surface of about 70 by 110 kilometres (43 mi × 68 mi) in the northeastern Tibesti mountains, with a steep drop towards the east and the north and gentler slopes in the south and west. Summits in the volcano include Boubou, Chebedo, Godoon, Kazena Lulli, Kégueur Tédi, Mouskorbé, Tarso Adar, Tarso Aozi, Tarso Chididemi, Tarso Goziydi, Tarso Kozen and Tarso Toudougou. Of these Mouskorbé reaches a height of 3,376 metres (11, 076 ft). Tarso Emi Chi has erupted a number of volcanic series such as the "black series" and the "white series", which consist of basaltic andesite, rhyolite and trachyte. Syenite intrusions have been found as well, the black series consist mainly of basalt. The "white series" is usually more heavily eroded than the "black series". There is no evidence of historical eruptions at Tarso Emi Chi, but volcanic products overlie diatom beds of fo
