Reger, D.B., and Price, P.H., 1926, Mercer, Monroe, and Summers Counties [West Virginia, with sections on paleobotany and paleontology by D.B. Reger, David White, G.H. Girty, and W.P. Prouty]: West Virginia Geological Survey [County Reports and Maps], [CGR-15], 963 p., (incl. geologic map, scale 1:62,500)


Summary:

Pg. 294, 318-320. Upper Belcher sandstone --greenish-gray, massive, medium coarse ledge, 15 to 40 feet thick, underlying Bratton shale and overlying Upper Belcher shale. Upper Belcher shale --red shale, with lenticular streak of carbonaceous fire clay near middle and with marine fossils; thickness 15 to 30 feet. Rests on Lower Belcher sandstone, which consists of greenish-gray massive or flaggy micaceous sandstone, 15 to 45 feet thick, which rests on Lower Belcher shale, a red sandy shale 20 to 30 feet thick, carrying marine fossils. All are members of Bluestone group [Bluestone formation] and all are exposed just north of Belcher School, in Mercer County, southeastern West Virginia. Belcher sandstone recognized in southeastern West Virginia; Belcher shale recognized in southeastern West Virginia and southwestern Virginia (Tazewell County). Age is Mississippian.
[The Bluestone group is a term used by some geologists to include same rocks as Bluestone formation of USGS reports (US geologic names lexicon, USGS Bull. 896, p. 222).]
