Darfur Dome

Darfur Dome or Darfur Volcanic Province is an area about 100x400 km in area in Western Sudan, the result of a volcanic plume[1][2] which created its best-known and central feature, Deriba Crater. It also produced the surrounding Marra Mountains (Jebel Marra)[3][4] and Tagabo Hills, formed around 16 and 10 Ma., and the Meidob Hills which arose around 6.8 Ma.[5] The plume is linked to stress resolution along the Central African Fault Zone.
