An extensive development of reef facies accounts for a large percentage of the limestone deposits in shallow peripheral areas of the Delaware and Midland Basins (Dolton et al., 1979; Hills, 1984). Permian rocks are extremely heterogeneous, generally grading upward from a clastic-carbonate sequence into an evaporate sequence.

Dallas Paleontological Society

At the time of the Denton Clay, deeper water covered the area. The calcium carbonate deposits hardened into a micritic limestone. Clay units have abundant shell debris and some burrowing is evident. Marl beds vary from argillaceous limestone to calcareous clay. Limestone units are dark gray when fresh and can have thin (<0.6 ft.) Gryphea beds.
