Summary:
The High Shoals Granite, here named, occupies an area of batholithic size in the Kings Mountain belt, NC. It was informally named High Shoals granitic gneiss by Horton and Butler (1977), to distinguish it from nonfoliated granites like the type Yorkville near York, SC. It was previously mapped as Yorkville Granite by Keith and Sterrett (1931), and as Yorkville Quartz Monzonite by Espenshade and Potter (1960). It consists of coarse-grained, porphyritic, gneissoid biotite granite or granitic gneiss. Uranium-lead isotopic data on zircons indicate a Pennsylvanian age of about 317 Ma.
