Summary:
Name Hampshire formation, applied by Darton to exposure of Late Devonian redbeds in Hampshire Co. is here revived for rocks previously called "Catskill" in WV. Redbeds of Catskill Mountains in NY are of Portage and Hamilton age, while those in Appalachian region are post-Chemung. Formation is well developed along the Potomac where it attains maximum thickness of about 3,000 ft in Morgan and Hampshire Cos.; thins westward and southward. Includes red and green sandstones and shales. Underlies "Pocono facies"; overlies Chemung Formation. Name Hampshire also reinstated by the Maryland Geological Survey.
