Lithology description: The Henryhouse formation was originally described by C. A. Reeds in 1911 (pp. 261-262) as consisting of "bluish to yellowish, thin- to moderately thick-bedded earthy limestone and intercalated shale beds in the lower 180 feet, while the upper 43 feet is of white marly beds." Amsden (1958): (5Y 8/4) yellowish gray to pale greenish-gray (lOY 8/4) argillaceous calcilutite (marlstone) with a few scattered beds of calcarenite. Average grain-size of the calcilutite well below 1/16 mm; calcarenites coarser, probably with a slightly reduced insoluble content. One rock sample yielded about 8% HCl insolubles ; the washecl residues consist largely of clear, subangular, silt-size quartz; few arenaceous Foraminifera. Rock is slightly dolomitic, the acid soluble portion having 4.5% MgC03. Bedding nodular, up to 2 or 3 inches in thickness. N0 chert observed.
Environment:carbonate indet.
