Summary:

Name New Scotland beds or limestone introduced for shaly limestone exposed at town of New Scotland, Albany Co., NY. Underlies Becraft limestone and overlies Coeymans limestone. Included in Helderbergian group. Equivalent to Delthyris shaly limestone (the paleontologic name for these strata). Age is Early Devonian.

Summary:

Beds A and B of the newly named Bald Hill Bentonite Beds occur within the New Scotland Formation in PA and WV and within the correlative Corriganville Limestone in MD. Bed C occurs near the base of the overlying Mandata in all three states. In NY, Beds A, B, and C occur within the middle member of the Kalkberg Limestone.

Summary:

New Scotland Formation of Helderberg Group is mapped in northwestern NJ. Upper section is dark-gray, siliceous, laminated shale containing medium-dark-gray, very fine-grained limestone pods and scattered beds and lenses of medium-gray, fine-grained argillaceous, fossiliferous limestone. Limestone contains small, dark-gray chert nodules. Lower section is medium-dark-gray, siliceous, calcareous, fossiliferous shale containing beds and lenses of medium-gray, fine-grained, argillaceous, very fossiliferous limestone. Contains nodules, lenses and local irregular beds of dark-gray chert. Total thickness of formation is approximately 75 ft. Lower contact with the Coeymans Formation of Helderberg is abrupt, at the top of a calcareous quartz sandstone. Underlies Minisink Limestone of Helderberg Group. Age is Early Devonian.
