The basaltic Kutum volcanic field, in the northern Darfur area of western Sudan, is located SW of the larger Meidob volcanic field. As with other Saharan volcanic fields, Kutum (also known as the Tagabo Hills or Berti Hills) contains very well-preserved cones, lava flows, and explosion craters. They were considered to be of late-Pleistocene or even Holocene age (Almond, 1974). Franz et al. (1997), however, assigned only Tertiary age ranges for rocks from Tagabo Hills.
