Summary:
Composition of the Glenerie limestone ranges from limestone to solid chert beds, soft shale, and conglomerate. Beds are very blue to nearly black in fresh exposures; characteristically weather buff brown. Thickness is about 30 ft in type exposure. Overlies the Port Ewen beds in type area, but overlies the Connelly conglomerate farther to south.

Summary:
Glenerie Formation mapped in northwestern NJ as lowest of three units in Oriskany Group. [Glenerie was originally assigned to the Oriskany by Chadwick (1908), but GNU records show no other reference with this allocation.] Described as medium- to dark-gray, fossiliferous, thin- to medium-bedded, cherty, fine-grained silty limestone. Unit is thin in the southwest and thickens to the northeast where it constitutes most of the Oriskany Group. Formation thickness ranges from 55 to 170 ft. Lower contact with Port Ewen Shale of Helderberg Group is gradational. Underlies Shriver Chert (middle unit of Oriskany), Ridgeley Sandstone (upper unit of Oriskany), or Esopus Formation. Age is Early Devonian.
