Wise Formation and Gladeville Sandstone

Wise Formation (Campbell, 1893) . Sandstone, siltstone, shale, limestone, coal, and underclay. Sandstone, lithic, feldspathic, micaceous, argillaceous, carbonaceous locally, light- to medium-gray to moderate- and pale-yellow-brown, fine- to coarse-grained, locally pebbly, thin- to thick-bedded, cross-bedded to even-bedded, locally massive, well-cemented; contains fragments of shale, siltstone, and carbonized plant fossils locally. Siltstone and shale, lightolive- gray, medium- to dark-gray and grayish-black, contains siderite ironstone in very-thin beds and nodules, carbonized plant fossils; invertebrate fossils in dark-gray to black shale and micrograined limestone in the upper part of formation (Miller, 1969; Miller and Roen, 1973; Nolde, Henderson, and Miller,1988; Nolde, Whitlock, and Lovett, 1988a). Limestone, medium- to dark-gray, micrograined, in very-thin lenses and beds in shale and siltstone in two to three zones in lower part of formation (Taylor, 1989; Whitlock, Lovett, and Diffenbach, 1988). Coal interbedded with shale, siltstone, and sandstone. Underclay, light-gray, root casts, beneath coal; as much as 5 feet thick under the Williamson coal bed in Buchanan County (Henika, 1989b). A dark-gray to brownish-gray, flint clay in the Phillips (Fire Clay; No.7) coal bed in northern Lee County (Miller and Roen, 1973) and western Wise County is a volcanic ash deposit (Seiders, 1965) that covers parts of Kentucky, Tennessee, Virginia and West Virginia; it has been dated at an age of 311 - 312 million years (Lyons and others, 1992; Rice and others, 1990). Base of formation at bottom of Dorchester coal bed. Thickness 2150 to 2268 feet. Gladeville Sandstone (Campbell, 1893). Quartzarenite and sublitharenite, silica cemented, locally feldspathic and micaceous, conglomeratic, white to medium-gray to pale-yellowish- orange, weathers yellowish-gray, fine- to medium-grained, thin- to very-thick-bedded, thin- to thick- planar and trough cross-beds, slabby to blocky, contains fragments of dark-gray shale, coal, and fossil plants and quartz-pebble conglomerate near base. Underlies Wise Formation in northeastern Lee, southern Wise, and western Dickenson counties and pinches out in northern Wise and eastern Dickenson counties. A sandstone in the underlying Norton Formation below the Norton coal bed, as much as 100 feet below the stratigraphic position of the Gladeville, was misidentified as Gladeville in Lee County, and parts of Wise, Dickenson, and in Buchanan counties prior to the 1980s (Henika, 1989a; Miller and Roen, 1973; Nolde, Whitlock, and Lovett, 1988b; Whitlock,1987). Because of this, coal beds in the upper Norton and lower Wise Formations were miscorrelated where the Gladeville was absent. Thickness 0 to 65 feet.
