Abstract

The Poundridge area in northeastern Westchester County, New York, is underlain by the Poundridge and Siscowit granites, the Fordham gneiss, Inwood marble, and the Manhattan formation, comprising the New York City group. Field evidence, including the fact that the Lowerre quartzite does not seem to exist, leads to the conclusion that the New York City group is a conformable sequence either of entirely Precambrian or Paleozoic (pre-upper Ordovician) age. It thus cannot be correlated with the Precambrian Highland gneiss and lower Paleozoic Poughquag quartzite-Wappinger limestone-Hudson River shale sequence of Dutchess County to the north.
