Summary:

Corr. chart. Reynolds Sandstone Member of Four Corners Formation of Breathitt Group (KY); Reynolds Sandstone Member of Wise Formation (VA). In southeastern Kentucky, is a member in lower part of Four Corners Formation; lies below Low Splint (Morris, No. 11) coal bed and above Magoffin Member of Four Corners Formation. In southwestern Virginia, is a member in upper part of Wise Formation; lies below Morris coal zone and above Magoffin Member of Wise Formation. Age is Middle Pennsylvanian (Westphalian; Atokan).
[Correlates with beds below the Winifrede coal and above the Hazard No. 4 coal, which Peppers (1996, GSA Memoir 188, p. 9, pl.) placed in Westphalian C, TORISPORA SECURIS-T. LAEVIGATA (SL) miospore assemblage zone of western Europe. Eble and others (2009, Kentucky Geol. Survey, ser. XII, Spec. Pub. 10, fig. 5.2) placed the Winifrede coal zone of West Virginia at the Duckmantian/Bolsovian (Westphalian B/C) boundary on basis of miospores. Unpublished collections from overlying Stoney Fork Member of Princess Formation in Kentucky, and its equivalents, informal Lake City member of Cross Mountain Formation in Tennessee and Blunt Run (Boggs) limestone of Pottsville Group in Ohio, yielded distinctive conodonts correlative with the marine Aegir bed (=base of Westphalian C) thus shifting the Four Corners, Vowell Mountain, lower part of Cross Mountain, and upper part of Pottsville, downward into Westphalian B (R.G. Stamm, USGS, pers. commun., Oct. 17, 2013).]
