Pulaski and Whetstone Gulf Formations (NYOpw;1)

State	New York
Name	Pulaski and Whetstone Gulf Formations
Geologic age	Upper Ordovician
Lithologic constituents	Major Sedimentary > Clastic > Siltstone Sedimentary > Clastic > Mudstone > Shale
Comments	part of Lorraine, Trenton, and Black River Groups up to 1600 ft. (490 m). Secondary unit description from USGS website (ref. NY046) and reference NY035: Pulaski Formation of Late Ordovician age (Cincinnatian, Maysvillian to early Richmondian) is used in report. Nautiloid taxa of Maysvillian to early Richmondian strata on OH [Bull Fork Formation according to fig. 2] are also characteristic of "Lorraine fauna" of Foerste (1914). This fauna also is found in coeval Pulaski Formation in NY and Georgian Bay Formation in southern Ontario (Frey, 1995).
