Organizing and summarizing search results for youManhattan is built on three strata known as Manhattan Schist, Inwood Marble, and Fordham Gneiss. The bedrock underlying much of Manhattan is a mica schist known as Manhattan schist of the Manhattan Prong physiographic region. It is a strong, competent metamorphic rock that was produced when Pangaea formed. The Taconian Orogeny, which occurred approximately 450 million years ago during the Middle Ordovician Time Period, is responsible for the formation of Manhattan. The island does not change in chemical make up much over the years, but the formation beneath it does due to Plate Tectonics.4 Sources Explore New York’s Geological Features – A Journey Through Time
