Pg. 50-51, and under county descriptions. Newton sandstone. Top member of Bonair sandstone. Consists of 50 to 175 feet of soft coarse white, yellow, or reddish-white micaceous sandstone, generally strongly cross-bedded. In places there are thin ripple-marked beds and one or two coal beds. In northern part of field this sandstone rests on Eastland shale lentil of Bonair sandstone. In southern part of field it rests on Whitwell shale.
Recognized in Cumberland, Grundy, Hamilton, Van Buren, White, Bledsoe, Sequatchie, Rhea, and Marion Cos., southeastern TN. Named for fact that it occurs at Newton Post Office, in southwestern corner of Cumberland Co., southeastern TN.

Pg. 4, 19, pls. 2, 3, 4, 12-B. Newton sandstone of Crab Orchard Mountains group. Assigned to Crab Orchard Mountains group (new). In type area, massive, medium-grained, cross-bedded, and locally conglomeratic; over most of outcrop area, fine- to medium-grained, massive, friable. Attains maximum thickness, 110 feet, in type area; thins abruptly along a northeast-southwest line. Underlies Vandever formation; overlies Whitwell shale, local unconformity. Conglomeratic phase of the Newton sandstone in southern Cumberland and northern Bledsoe Counties, [eastern Tennessee], was the type "Herbert conglomerate" erroneously considered by Nelson (1925) to be older than Newton; the shale thought to be between the sandstones and named "Eastland shale" is actually Whitwell shale. "Herbert conglomerate" and "Eastland shale" discarded [abandoned]. [Age is Early Pennsylvanian (Pottsville).]
[GNC remark (ca. 1966, US geologic names lexicon, USGS Bull. 1200, p. 2735): The USGS currently classifies Newton Sandstone as a member of Crab Orchard Mountains Formation on basis of study now in progress.]

New nomenclature defined for rocks of Early Pennsylvanian age in northwest GA. Newton extended to GA as member of Crab Orchard Mountains Formation. On Lookout Mountain, consists of cross-bedded bench-forming sandstone about 110 ft thick. Overlies Whitwell Shale Member; underlies Vandever Member.

(East-central sheet; not separately mapped.) Newton Sandstone of Crab Orchard Mountains Group. Gray to brown or pink, fine- to medium-grained sandstone, locally conglomeratic. Thickness as much as 200 feet; average about 90 feet. Lies below Vandever Formation and above Whitwell Shale; both of Crab Orchard Mountains Group. Age is Pennsylvanian.

Newton Sandstone of Crab Orchard Mountains Group mapped in Roane Co., eastern TN. Consists of light- to medium-gray, fine to coarse-grained, thin- to thick-bedded sandstone with a few shale and coal laminae; dark-gray sandy shale with a few sandstone laminae; and medium-gray siltstone. Thickness ranges from 10 to 120 ft. Overlies Whitwell Shale and underlies Vandever Formation, both of Crab Orchard Mountains. Age is Early Pennsylvanian.
