Isotopic evidence for a tectonic boundary between the Kings Mountain and Inner Piedmont belts, southern Appalachians
Journal Article

· Geology; (United States)
Concordant U-Pb zircon ages of approx. 320 Ma for the deformed High Shoals Granite of the Kings Mountain belt (KMB) extend the range of known Alleghanian (late Paleozoic) deformation and metamorphism in the southern Appalachian Piedmont. Isotope systematics in KMB rocks suggest an affinity with terranes to the southeast rather than with the Inner Piedmont belt to the northwest. Lead-isotope systematics in meta-igneous rocks of the KMB suggest direct or indirect mantel derivation with little or no crustal contamination.
