A sill is a type of intrusive igneous rock body that is tabular and concordant, meaning it is parallel to the layering of the surrounding rock. Sills are formed when magma is injected into existing rock layers and solidifies underground. They are often found in sedimentary rock formations.

The Palisades Sill is primarily composed of diabase, which is a type of igneous rock. Formed from the cooling and solidification of magma, diabase is characterized by its dark color and fine-grained texture. The sill itself was intruded into sedimentary rock layers approximately 200 million years ago during the Jurassic period. Its formation is part of a larger geological feature known as the Newark Supergroup.
