Volcanic and metavolcanic rocks intruded by the Um Ara granites, a larger oval-shaped monzogranite pluton and a smaller alkali-feldspar microgranite emplaced at its northern contact. Both granites are peraluminous to metaluminous. The U- and Th-bearing alkali-feldspar granite is cut by pegmatite veins and locally abundant veinlets of purple and colourless fluorite. Secondary uranium minerals occur as disseminations, as aggregates, and as cavity fillings.
Um Ara alkali-feldspar granites.
Located in the south Eastern Desert.
