Harlan Sandstone

Harlan Sandstone (Campbell, 1893) Sandstone, siltstone, shale, and coal. Sandstone, feldspathic, moderately quartzose, argillaceous, medium-gray, fine- to coarse-grained, thin- to thick-bedded, cross-bedded; quartzose sandstone is pebbly, moderately resistant, cliff-forming, and in lenticular bodies at base of formation where it fills channels (Miller, 1969; Miller and Roen, 1973). Sandstone comprises as much as 48 percent of formation. Siltstone and shale, medium- to dark-gray and brown, locally reddish-brown; contains 22 discontinuous coal beds. Miller (1969) changed the name from Harlan Sandstone (Campbell, 1893) to Harlan Formation because of the heterogeneous lithology and defined the base as the top of the High Splint coal bed. It is as much as 650 feet thick in northern Lee and western Wise counties, adjacent to Kentucky; upper part removed by erosion in Virginia (Miller and Roen, 1973; Nolde, Henderson, and Miller, 1988; Nolde, Whitlock, and Lovett, 1988a).
