Reconnaissance geology of the Wadi Amq Quadrangle, sheet 18/41 C, Kingdom of Saudi Arabia
The Wadi Amq quadrangle (sheet 18/41 C) lies between lat 18?00' and 18?30' N. and long 41?00' and 41?30' E. and encompasses an area of 2,937 km2, of which only about 150 km2 is land; the remainder is covered by the Red Sea. The only geologic formations exposed in the quadrangle are Quaternary volcanic rocks and surficial deposits. Most of the volcanic rocks are basalt that was extruded during a continuation of the opening of the Red Sea rift. The Quaternary surficial deposits include those of shallow bank and coral reefs, carbonate sand, sabkhahs, pediment and plains, and alluvial sand and gravel. The coral reefs could possibly provide raw material for a cement industry if required, and the sabkhahs might yield useful salts; otherwise the quadrangle has no economic mineral potential.
