Meidob Volcanic Field : ウィキペディア英語版 | Meidob Volcanic Field The alkaline Meidob volcanic field is a volcanic field at the northeast end of the Darfur volcanic province in western Sudan, adjacent to the Kutum volcanic field. It covers an area of 5,000 km² with nearly 700 late Cenozoic vents. The volcanic field was constructed over an uplifted Precambrian igneous and metamorphic basement and is elongated in an east-west direction. Basaltic scoria cones and associated lava flows dominate, but trachytic-phonolitic lava domes, tuff rings, and maars are among the youngest volcanic products. The lava from the scoria cones produced a broad lava plateau. The central part of the field consists of younger phonolitic lava flows, trachytic pumice-fall deposits, ignimbrites, and maars. The youngest dated eruptions about 5,000 years ago produced a tuff ring and a lava flow. The Midob people, a Nubian ethnic group, inhabit the region. ==See also==
