Pg. r148. Newfoundland quartzite. Usually a light-colored quartzite but locally conglomeratic. At some localities carries fossils which correlate it with basal Devonian Oriskany quartzite. The formation name here proposed is an allusion to the exposure of the quartzite at Newfoundland, New Jersey, where its lithologic and paleontologic characters are well shown and were described by Britton and Merrill in 1886 (New Jersey State Geol. Rpt.). Is exposed at several other points along margin of the Devonian outlier in both New York and New Jersey. Underlies Monroe shales. Age is Middle Devonian.

Unit referred to here as Newfoundland grit consists of 115 ft of rather thin-bedded hard greenish sandstone underlain by 100 ft of heavy-bedded fine-grained conglomerate. Contains a mixed Oriskany-Corniferous fauna. Grades into overlying Monroe shales. Overlies Decker Ferry limestone, but nowhere seen in contact with that formation, so that intervening Helderbergian strata may be present. Ledges of this grit have been found at Newfoundland, Morris Co., NJ.

Kanouse sandstone introduced to replace [objectionable] name "New Foundland grit." [Kanouse is a] thick-bedded fine-grained conglomerate below and greenish sandstone above. Thickness 215 feet. Underlies Pequanac [Cornwall] shale and rests on Decker limestone. Carries Onondaga fauna. Exposed in valley west of Kanouse Mountain, Passaic County, New Jersey.
