Lithostratigraphy Of The Cane Hill Member Of The Hale Formation (Type Morrowan), Northwest Arkansas, Robert T. Liner
Journal of the Arkansas Academy of Science
The Hale Formation (lower Morrowan Series) is a sequence of sandstones and shales divided into the Cane Hill(lower) and Prairie Grove Members. In Washington County, Arkansas, the type Cane Hill consists predominantly of interbedded fine-grained, noncalcareous sandstones and silty shales often with a pebble conglomerate at its base. The member rests unconformably on Chesterian Strata of either the Pitkin Formation or underlying Fayetteville Formation, and it is unconformably overlain by the Prairie Grove Member. In Washington County, the Cane Hill exhibits a slight thickening trend to the south and east. Interpretation of sedimentary structures indicates that the Cane Hill was …
