Definition of Possible Stratigraphic Units in North Central Long Island, New York, Based on Detailed Examination of Selected Well Cores

Eugene E. Foord (2), William R. Parrott, Dale F. Ritter


Unconsolidated sediments from two deep wells located in the north-central portion of Long Island, N.Y., were examined and analyzed with respect to clay mineral, heavy mineral, and textural parameters. Utilizing the data obtained, five stratigraphic units are postulated for this area. Differences in clay mineral assemblages provided the most definite means of establishing unit boundaries. These differences are generally accompanied by definite textural changes and heavy mineral assemblage variations.

The lowest unit is probably late Cretaceous in age, with the upper three units being most likely late Pleistocene in age. The remaining unit (Unit II) is stratigraphically complex, and its age may be either Tertiary or early Pleistocene, or both.

Whether these units have any regional significance awaits further similar work with drill core samples in the region.
