Jebel Kuror And Jebel Mansuri

A north-south trending ridge of 15x3 km standing a few hundred metres above the surrounding plain provides a lonely landmark in an otherwise featureless plain. A more northerly peak on the ridge is Jebel Kuror while Jebel Mansuri is at the southern end of the ridge. There are two unnamed hills 3 and 17 km to the south-southeast. All these hills are built of quartz syenites which appear to form arcuate and overlapping ring dykes younging to the south. The Kuror-Mansuri rocks consist of perthite, rare to 40% quartz, aegirine-augite, riebeckite-arfvedsonite and minor opaques, apatite and rare zircon (J.R. Vail pers. comm., 2000).
