Dam Formation

The formation was first described in a report in 1935 by Steineke and Kock. However, this report was unpublished. It was first described in published material by Powers in 1968 in Saudi Arabia, and by Cavelier in 1970 in Qatar.^[3]

The formation in Saudi Arabia and the U.A.E. was deposited in a terrestrial environment, while the formation in Qatar was deposited in a marine habitat as evidenced by the multiple marine animals found in the formation.^[2][3]
