The Tomkins Cove Quarry, operated by Tilcon New York Inc., is located in northern Rockland County along the western bank of the Hudson River. The quarry was formerly an active open pit limestone quarry that supplied crushed stone for construction to the surrounding area, New York City, and Long Island.
The active mine area is 110 acres. The primary crusher and secondary processing mill are all located on the North end of the quarry. A majority of the stone was shipped by barge on the Hudson River.
Geology: The quarry is located in a narrow stretch of the Middle Ordovician (460.9- 471.8MA) Balmville Limestone (sometimes called Trenton Limestone) which is exposed on either side of the Hudson River. The fine grained limestone is consistent throughout and quite pure regardless of its varying colors from gray to tan. The folded beds seen in the quarry were formed during the accretion of the super continent Pangea. The beds are folded into a synclinal structure when looking across the pit. On a smaller scale there are tight folds with shaly interbeds.
Mineralization is rare in the quarry with pyrite, chalcopyrite, dolomite, calcite, and quartz identified from the quarry. Mineralization occurs in the fractures and breccias throughout the quarry. Some calcite crystals in fractures reach 5 inch. Pyrite is responsible for iron staining.
There is also evidence that the Ramapo fault intersects in/near to the quarry.
