Discovery of phosphate rock in Saudi Arabia and recommended program of further study

In the period August 12, to September 3, 1965, I was assigned as a phosphate specialist to the U.S. Geological Survey Group in Saudi Arabia to work in cooperation with the Ministry of Petroleum and Mineral Resources of the Saudi Arabian Government.  My assignment was to evaluate the phosphate potential of Saudi Arabia, train a Saudi Arabian geologist counterpart in modern techniques of phosphate exploration, and to help set up a program of exploration.  These objectives have been largely fulfilled.  In addition phosphate rock was discovered.
