Metallic-mineral assessment of the Aban Al Ahmar quadrangle, sheet 25F, Kingdom of Saudi Arabia

Comprehensive detailed interdisciplinary study assesses the metallic-mineral-resource potential in the Aban Al Ahmar Quadrangle of the Kingdom of Saudi Arabia, located in the eastern margin of the northeastern Arabian Shield, utilizing techniques of geophysics, geologic mapping, remote sensing and geochemistry. The landscape of the study area is characterized by isolated mountain groups, inselbergs, and local tracts of dissected hills separated by broad, low-relief peneplain. Topics covered include mining and exploration history; geological setting; interpretation of geophysical anomalies; limonitic hydrothermally altered and mineralized rocks; geochemical interpretation; mineral resource potential; skarn deposiits associated with intermediate igneous rocks; gold deposits; tin/tungsten skarn deposits; etc.

Mineral investigations between Khamis Mushayt and Bi'r Idimah, Saudi Arabia

Mineral investigations between Khamis Mushayt and Bi'r Idimah in the Asir quadrangle, sheet 1-217 (Brown and Jackson, 1959) began September 24, 1964 and ended November 20. Total distance travelled was 6264 kilometers. Sixteen camps were set, and 483 samples of various geologic materials, principally wadi sands, laterite, and gossan, were taken. Not all the area originally scheduled to be covered was examined, owing principally to more time being spent on scheelite and laterite than originally planned. No work was done in the area covered by the two 1:50,000 mosaics numbered 9E and 8E. They will be blocked out in January 1965. The area completed includes parts or all of the 1:50,000 scale mosaics numbered 8B, 8C, 8D, 8F, 9B, 9C, 9D, and 9F. No megascopic indication of an exploitable mineral deposit of any type, except the small occurrences of marble cited in the October 1964 report and slate already in use, was discovered. A previously unknown ancient working was found, but it is small. Unless spectro-chemical analysis of samples discloses anomalously great amounts of some element, the area examined must be considered as unfavorable for ore deposits, except possibly the gossan exposed south of Bi'r Idimah.
