An injection complex of early pre‐Cambrian age is exposed in the Elk Creek anticline in Grayson County, Virginia. There, sedimentary rocks and diorite have been intruded by the Striped Rock and the Carsonville granites. The granites have metamorphosed, injected, reacted with, and replaced the older rocks to form many mixed types. This injection complex is part of a large area of similar rocks that form the core of the Catoctin Mountain‐Blue Ridge uplift in Virginia, and is much older than the overlying volcanic series of later pre‐Cambrian age. ©1942.
