English: The Bayuda volcanic field is located near the center of the Bayuda desert of NE Sudan. The numerous small cinder cones that trend horizontally across the center of the volcanic field in this Space Shuttle image were erupted along a WNW-trending line. Lava flows, one of which was erupted about 1100 years ago, are visible in this image, but about 10% of the vents are explosion craters. Bayuda was constructed over Precambrian and Paleozoic granitic rocks, which form the darker areas at the lower right.
