Comparative Anatomy of a Pottsville Lithic Arenite and Quartz Arenite of the Pocahontas Basin, Southern West Virginia: Petrogenetic, Depositional, and Stratigraphic Implications.
J Sedimentary Petrol 1980 Mar; 50(1):3-20
Appalachian carboniferous stratigraphy remains controversial partly because of unclear petrogenetic, depositional, and stratigraphic relationships displayed by pottsville sandstones, which have been interpreted as being of either alluvial or barrier-beach origin. Two associated sandstones of the New River Formation of southern West Virgina provide the setting for a detailed examination of this problem. The Lower Raleigh lithic arenite consists of elongate and lobate, dip-oriented bodies that display erosional bases, interfinger laterally with shales, fine upward at the top, and are unidirectionally trough cross-bedded basinward. The Upper Raleigh quartz arenite consists of elongate, dip-oriented bodies updip in the basin and elongate and lobate, strike-oriented bodies downdip. The quartz arenites display erosional bases, interfinger laterally with shales, fine upward at the top, and are unidirectionally planar cross-bedded basinward. Evidence suggests that Lower Raleigh detritus was derived from a southeasterly metamorphic-sedimentary source terrane and deposited in high-constructive lobate deltas.
