During investigation of the Jabal Eghei area in southern Libya and the  production of geological maps at a scale of 1:250 000 (Tibesti sector, sheet  Wadi Eghei NF 34-1 and NF 34-2), regional prospecting for mineral raw  materials was performed. Radiometric survey of observed targets at the sites  indicated two significant uranium mineralizations in rhyolites, and some  smaller ones in granites that are in close contact with rhyolites. Rhyolites  are located in the central part of the investigated region. They cut through  granite rocks. The first mineralization is in the central part of the  rhyolite region, which is mostly composed of silificated rhyolites. The  second one was discovered near the granite-rhyolite contact zone,  characterized by the presence of silicified breccia rocks. These findings  were confirmed by laboratory measurements of more than seventy samples  collected in the area, using high resolution gamma-ray spectrometry. The  concentrations of uranium in these mineralizations were found to range from  approx. 50 mg kg-1 to more than 600 mg kg-1. The latter value is about 240  times above the Earth’s average. Besides uranium, these measurements have  also given concentrations of thorium and potassium. Additional geochemical  analysis was performed on samples taken from locations where uranium  anomalies were discovered using ICP-MS technique, in which concentrations of  more than forty elements were determined. Uranium mineralizations are  accompained by increased contents of silver (up to 17 times), arsenic (up to  8 times), molybdenum (up to 50 times), mercury (up to 9 times), and lead (up  to 14 times), in regard to the Clark’s values. These results warrant a  continued investigation of this region because of potential interest in the  discovery of nuclear mineral raw materials
