The Moyale graphite deposit, Southern Ethiopia
Abstract
Precambrian metamorphic rocks of southern Ethiopia, belonging to the Pan-African (Mozambique Belt), host the Moyale graphite deposit. The principal rock units are amphibole schists, quartz-feldspar-mica schists, granodiorites, quartzites and garphite schists. Graphite-bearing units are hoste by quartzites and quartz-feldspar-mica schists and generally form continuous bodies extending for hundreds of meters. A regional variation in grade and flake size of the graphite is noted. From this lateral extent and mode of occurrence, the graphite is believed to be sedimentary in origin.
