The Karasuk area in the Kenya-Uganda border region is divided into four main physical units: the Uganda plain in the extreme southwest, the Karasuk hills with isolated summits over 9000 ft, a dissected plateau at about 5100 ft between the Uganda plain and the Karasuk hills, and the Turkwel plain at approximately 2500 ft, separated from the Karasuk hills by the eastward-facing Turkwel escarpment. Relationships and correlation of these units with the erosion surfaces of the area and in neighboring areas are discussed. The western half of the area is composed mainly of a metamorphic and igneous complex containing recrystallized sedimentary and volcanic rocks of late Precambrian age and incorporating a body of olivine norite and alkaline and acid to ultrabasic minor intrusions. Superficial Pleistocene and Recent deposits cover most of the eastern half (Turkwel plain). The Precambrian rocks show the effects of two major periods of folding; the first fold axes trend east-west and the second trend north-south. A third episode of less intense folding is indicated about east-west axes. A copper and a graphite deposit are described in some detail, the occurrence of gold, mica, columbite, beryl, samarskite, corundum, and limestone are noted, and water supplies are discussed.
