Geologic report series 11

Within the Precambrian Highlands of northern New Jersey and adjacent New York are several infolded and downfaulted belts of Paleozoic sediments. The easternmost of these belts, the Green Pond outlier, itself a downfaulted synclinal block, preserves Cambrian, Ordovician, Silurian, and Devonian rocks. The outlier extends for almost 55 miles northeastward from Flanders to Cornwall, New York, and attains a maximum width of 5 miles. The Paleozoic sediments of the outlier lie about 25 miles southeast of the main outcrop belt of the Appalachian Valley and Ridge Province of westernmost New Jersey, They represent sediments deposited approximately that much nearer the source areas to the east and provide a record of tectonic events and geographic conditions in the source area which are not detectable further west.This series has at times has been entitled Geologic report series, Geologic report (Trenton, N.J.), and ultimately Geological survey report (Trenton, N.J.)
