The mineral resource potential of the Harrat Nawasif, sheet 21/42 C, Ranyah, sheet 21/42 D, and Jabal Dalfa, sheet 21/43 C quadrangles, Kingdom of Saudi Arabia

Fenton, Michael D.

Abstract:

Areas with mineral resource potential in the Harrat Nawasif, Ranyah, and Jabal Dalfa quadrangles in the central Precambrian Shield of Saudi Arabia have been identified by reconnaissance rock geochemistry and inspection of ancient prospects. Locally anomalous areas in perthitic, alkalic granite terrane in the Ranyah quadrangle possibly contain niobium, zirconium, thorium, fluorite, rare-earth, tin, molybdenum, or copper mineralization. The reconnaissance rock geochemical survey in layered volcanic and volcaniclastic terrane in the Jabal Dalfa quadrangle identified a zinc anomaly in quartzite and a nickel-copper zone that is an extension of the Jabal Judayr prospect, where a low-grade, nickel-copper sulfide deposit is known. The Precambrian terrane in the Harrat Nawasif quadrangle has no known mineral resource potential.
