A mineral reconnaissance of the Jabal Sahah quadrangle, Kingdom of Saudi Arabia

A mineral reconnaissance of the Jabal Sahah quadrangle, Kingdom of Saudi Arabia, showed the presence of the anomalous elements silver, beryllium, molybdenum, niobium, tin, and tungsten and of anomalous amounts of chromium, nickel, lead, titanium, and vanadium. All anomalies are low except one for tin and one for tungsten in the granitic plug west of Jabal Sahah. Debris from this small plug contains as much as 1,000 ppm (parts per million) tin in wadi sand, and a concentrate from the sand contains as much as 40 ppm molybdenum and 1,000 ppm tungsten. The area of this small plug and the metamorphic rock around the plug should be studied in detail to learn distribution and value of tin, tungsten, niobium, and molybdenum in the rocks. Alkalic granite at Jabal Sahah contains beryllium,-molybdenum, tin, niobium, tungsten, and a low anomaly of lead.
