Also know, what kind of rocks are in upstate New York? The rocks in the region are mostly metamorphic, formed under great heat and pressure at depths of up to 30 kilometers in Earth’s crust.

Also the question is, what type of rock are the oldest rocks in New York State? The oldest rocks in non-Appalachian New York have traditionally been thought to be sandstones of the Potsdam Formation. The Potsdam sandstomes generally rest directly at a nonconformity with the much older, highly metamorphosed basement of the Adirondack Mountains dome.Serpentine rock is apple-green to black and is often mottled with light and dark colored areas.
Do all states have state rocks?
