Summary:
Named as a lentil in Gizzard formation. Named for Warren Point, a point 0.5 mi north of Monteagle, Grundy Co., southeastern TN. Outcrops as a bluff in its type locality. It is the first sandstone beneath Sewanee conglomerate from which it is, in places, separated by as much as 135 ft of beds. In other places, beds between Warren Point and overlying Sewanee thin out and Warren is in contact with Sewanee. Lower part of the Warren Point varies from thick and heavy cross-bedded sandstones to thin, slab-like, very fine-grained, ripple-marked, micaceous sandstones often containing partings of yellowish-gray or gray fissile shale containing white or pink plastic clay bands. Around Sewanee, Warren Point is a fine-grained, hard, nonconglomeratic sandstone. In eastern part of plateau and in northern part of southern Tennessee coal field, it is conglomeratic in lower part. Thickness varies from 25 to 175 ft. There is a marked erosional unconformity at base of Warren Point at widely scattered places over the entire field. In extreme southern part of the field Etna coal lies at base of sandstone; it was called cliff sandstone by Safford as it forms prominent bluffs in southern and central parts of plateau. [Age is Pennsylvanian.]

Summary:
Rank raised to Warren Point sandstone of Gizzard Group. Age is Pennsylvanian (Pottsville series). Overlies Raccoon Mountain formation (new); underlies Signal Point shale (new). At Pilot Falls, near Clifty, previously mistaken for Sewanee conglomerate because it is extremely conglomeratic there. Contains marine fossils on US Hwy 70-S west of Bon Air, where it splits into two thin sandstone beds. North of Monterey, it thins and equivalent strata are assigned to Fentress formation. Report includes geologic maps, cross sections, stratigraphic sections, and correlation chart.

Summary:
New nomenclature defined in this report for Early Pennsylvanian of northwest GA. Johnson's (1946) nomenclature was based on miscorrelation with rock units of TN. In type area (Lookout Mountain, GA) top bed of Lookout Sandstone is the Lower Conglomerate, not the Upper Conglomerate as shown by Pennsylvanian Subcommittee (R.C. Moore and others, 1944: GSA Bull., v. 55, no. 6); and top bed correlates with Warren Point Sandstone, not Sewanee Conglomerate as implied by Johnson's use of name Sewanee member of Lookout sandstone. On Lookout Mountain, bed Johnson calls Sewanee Member of Lookout Sandstone is same bed that Wanless (1946: GSA Mem 13) calls Warren Point Sandstone member of Lookout sandstone. On Sand Mountain, at Cole City, GA, Sewanee member of Johnson is top bed of Lookout sandstone of Hayes (1894: USGS Geol. Atlas, Folio 2), the Lower Conglomerate of McCalley (1904, GA G.S. Bull 12) and McCalley (1891: AL G.S. Spec. Rept 3), and Warren Point sandstone member of Wanless (1946). Johnson's map adjoins the type locality of Raccoon Mountain formation of Wilson and others (1956), where Sewanee member of Johnson directly overlies Raccoon Mountain formation and is thus the same unit as their Warren Point sandstone. In present report, the Warren Point is classified as a member of Gizzard Formation. Overlies Raccoon Mountain Member; underlies Signal Point Shale Member.

Summary:
Warren Point Sandstone mapped at northern end of Sand Mountain in TN, AL, and GA. Previous workers had mapped Warren Point Sandstone overlying Sewanee Conglomerate. Upper unit is indeed Warren Point, but lower unit actually correlates with a lower sandstone member of Raccoon Mountain Formation, here named Flat Rock Member.

Summary:
Warren Point Sandstone is here designated a formation of the Breathitt Group. It is restricted to the southern part of the study area where it is stratigraphically the lowest quartzose sandstone formation of the Breathitt. Cross sections show the unit in southeastern KY, eastern TN, western VA, and southern WV. It underlies shale, sandstone, and coal of the Bottom Creek formation (informal). In the south-central part of the study area, where the Bottom Creek is absent, the Warren Point underlies the Sewanee Sandstone and the two are combined as the Warren Point-Sewanee Sandstones, equivalent to and formally replacing the Middlesboro Member of the Lee Formation of Englund (1964). The Warren Point also replaces the White Rocks and Chadwell Members of the Lee. According to the author, formal nomenclature presented in this report for units occurring in KY has been accepted by the Kentucky Stratigraphic Nomenclature Committee. Units that occur largely outside KY are considered informal. Report includes correlation charts and cross sections.
