Mineral Resources of Phillips County

Abstract

The rocks exposed at the surface in Phillips County, north-central Kansas, consist of the Ogallala formation of Pliocene age, and the Pierre shale, Niobrara limestone, and Carlile shale of Cretaceous age. The known mineral resources of the county include oil, stone, sand and gravel, ground water, bentonite, volcanic ash, and an ever-present fertile soil. A brief discussion of the subsurface beds ranging in age from Precambrian to Cretaceous, and a description of the oil-producing areas are included.
