Summary:

Pg. 504, 516. Duck Creek chalk in Washita division [group]. Crumbling white chalky limestone alternating with chalky marls. Contains unique fossil fauna. Thickness 100 feet. Overlies Kiamitia [Kiamichi] clays (new) and underlies Fort Worth limestone in Indian Territory [present-day southern Oklahoma] and Grayson and Cooke Counties, northeastern Texas. Age is Early Cretaceous (Comanche).
[Named from Duck Creek, Grayson Co., northeastern TX. Notable exposure on southern slope of Duck Creek, north of Denison.]

Summary:

Duck Creek Formation. Limestone, aphanitic to biosparite, burrowed, beds 0.2 to 2 feet becoming thicker and more massive southward, light to medium gray; weathers yellowish brown; marine megafossils are PECTEN, oysters, echinoids, and ammonites. Clay, calcareous, in units 0.1 to 5 feet thick, medium gray to yellowish brown; weathers yellowish brown, forms low rolling hills. Thickness 25 to 35 feet. Lies above Kiamichi Formation and below Fort Worth Limestone. Age is Early Cretaceous.
[Mapped in Parker and Tarrant Cos., eastern TX.]

Summary:

Pamphlet [p. 6]. Duck Creek Formation. In Texas, upper part mostly marl interbedded with thin beds of marly limestone; lower part comprises 6- to 12-inch-thick limestone beds intercalated with gray to greenish-gray marly clay. Thickness approximately 100 feet. Lies above Kiamichi Formation and below Fort Worth Limestone. Age is Early Cretaceous. [Mapped along Red River and southward to Lake Ray Roberts (btw. Sanger and Pilot Point); in Cooke, Denton, and Grayson Cos., northeastern TX; in northern and central part of map sheet. Fort Worth and Duck Creek mapped undifferentiated from Lake Ray Roberts area to southern edge of map sheet.]
In Oklahoma, finely laminated blue-gray shale and gray, silty, shaly limestone containing abundant large cephalopods, [rocks included in lower part of Caddo Formation; see entry under Caddo].
