Summary:

Is Lower Cretaceous formation mapped in northeastern Kinney and northwestern Uvalde Cos, TX (Ouachita tectonic belt province). Overlies Glen Rose Formation. Overlain by McKnight Formation. Map unit described as: upper 80 ft--limestone, fine-grained, massive, miliolid- and mollusk-bearing; lower 60 ft--limestone, nodular, oysters and other mollusks common; total thickness 140 ft. Is not mapped north of [what appears to be an arbitrary] east-west line that separates the unit from the Devils River Limestone. In map explanation, is schematically depicted to be equivalent to Del Carmen Limestone, lower part of Devils River Limestone, and lower part of Fort Terrett Member of Edwards Limestone.
