The complex is mapped in a single, fault-bound area (horst) approximately 9 km long. It lies on the west side of the Richmond Basin, a Mesozoic rift basin, and on the east margin of the Goochland Terrane, a section of the Piedmont of Virginia that is tectonically distinct from the surrounding rocks. It is quarried for aggregate at the Boscobel Plant of the Luck Stone Corporation, near Manakin.[3][4]
