The geology of the State of New York is made up of ancient Precambrian crystalline basement rock, forming the Adirondack Mountains and the bedrock of much of the state. These rocks experienced numerous deformations during mountain building events and much of the region was flooded by shallow seas depositing thick sequences of sedimentary rock ...

The Rensselaer Plateau is a small plateau located in the central portion of Rensselaer County, New York; it generally encompasses significant parts of the towns of Berlin, Stephentown, Sand Lake, Poestenkill, and Grafton, along with small sections of several other nearby ...
The Clinton Group (also referred to as the Clinton Formation or the Clinton Shale) is a mapped unit of sedimentary rock found throughout eastern North America. [1] [2] The interval was first defined by the geologist Lardner Vanuxem, who derived the name from the village of Clinton in Oneida County, New York where several well exposed outcrops of these strata can be found.
In the first New York survey, the Marcellus Shale was placed below the Hamilton Group at the base of the Erie division of the New York system, but this taxonomy is obsolete. [ 41 ] In current practice, the Marcellus Shale (abbr. Dm or Dms) is classified as the basal unit of the Hamilton Group (Dh), [ 17 ] lying beneath the Mahantango Formation ...
