Lithology and Thickness

Lower part: Alternating layers of varying hardness and light grayish tan, more or less rubbly, compact, fine-grained limestone with occasional thin layers of fragmental limestone, oolite, and, recrystallized coquina; partings with abundant oyster and other fossil fragments. Locally there is limited dolomitization.

Upper part: Fragmental limestone interbedded with compact limestone. Several breccia layers occur near, and at, the base. Scattered quartz sand grains are also present near the base. Some of the brecciation is taken to suggest beds of anhydrite since removed by solution may once have been present.

Lithology Pattern:

Limestone

Relationships and Distribution

Lower contact

Regionally, the schematic strat column indicates the next older unit as Hith Anhydrite Fm

Upper contact

Regionally, the schematic strat column indicates the next younger unit as Yamama Fm. In Kuwait, the next younger is the Minagish Fm.
