Late Cretaceous - Early Cretaceous
66 - 145 Ma



ID: 2209552
Benton group

Age: Cretaceous (66 - 145 Ma)

Stratigraphic Name: Carlile Shale; Greenhorn Limestone; Graneros Shale

Description: Consists of three formations in Denver Basin: in descending order, Carlile Shale (Upper Cretaceous), Greenhorn Limestone (Upper Cretaceous), and Graneros Shale (Upper and Lower Cretaceous). Carlile Shale consists of upper grayish-brown, hard calcarenite containing abundant shell fragments (Juana Lopez Member), middle gray silty sandstone (Blue Hill Shale Member), and lower yellowish-gray, soft calcareous shale (Fairport Chalky Shale Member). The Carlile conformably overlies the Greenhorn Limestone, which consists of an upper gray, dense limestone and hard calcareous shale (Bridge Creek Limestone Member), middle gray, shaly calcareous sandstone (Hartland Shale Member), and lower grayish-brown, thin beds of hard calcareous sandstone and shale with a marker bentonite bed as base (Lincoln Limestone Member). Graneros Shale consists of dark-gray, hard, clayey shale and siltstone. In Blue River valley, the Juana Lopez Member of the Carlile forms a prominent marker above about 3 m of brown, soft sandstone sequence [Codell Sandstone Member of Carlile Shale of Berman and others (1980)] that, in turn, unconformably overlies sequence of hard black shale of the Graneros; lower 25 m of this sequence is a wavy black shale that contains abundant fish scales, equivalent to the Lower Cretaceous Mowry Shale. Benton Group is about 136 m thick in the 7.5-minute quadrangle (Wells, 1967) and thickens to the south, where it is about 182 m thick just south of Chatfield Lake (Scott, 1963b). In Blue River valley, the Benton is only about 80–100 m thick (Kellogg and others, 2002; Widmann and others, 2003). In Fraser basin, thickness is about 140 m, but thinned considerably by folding (Taylor, 1975)
