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.
