Pillow basalt is a volcanic igneous rock that forms when lava of basaltic compositionis erupted underwater. The rapid cooling of the lava by cold water on all sides forms the pillow-shaped bodies, which can then break open and extrude more of the hot lava from inside.

The true geologic margin of a continent ‑ where continental crust changes to oceanic crust ‑ is somewhere beneath the continental slope. However, subduction of a critical part of the anomaly record beneath Most of the province is underlain by Crescent Formation basalts, which are a thick deposit of marine volcanics accreted to the continent by subduction processes formed during the Eocene about 56 million years ago.
