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.
