The Caesars Head Quartz Monzonite is here named in SC and NC[?] for several irregularly shaped bodies of granitic rock that occupy 500 sq mi in the southeastern part of the Knoxville 2 degree quad. Biotite quartz monzonite and biotite granodiorite invade a terrane of older paragneiss and schist in the Piedmont. Resembles the less foliated phase of Henderson Gneiss. Age is younger than late Precambrian and at least as old as Carboniferous.

The Caesars Head Quartz Monzonite is here redefined as the Caesars Head Granite (to conform with IUGS classification of Streckeisen, 1973) of the Table Rock Plutonic Suite (this usage for SC only). The Table Rock Granite of Sloan (1907, 1908) and the Beverly Granite Gneiss of Cazeau and Brown (1963), refer to the same rock body and are here abandoned. The Caesars Head consists of banded to nonbanded biotite granitoid gneiss or gneissic granitoid, ranging in composition from monzogranite to granodiorite. Discontinuous black, biotite-rich bands alternating with white biotite-poor bands are common and typically folded. Interlayered and cross-cutting bodies of foliated, fine-grained, garnet-bearing muscovite-biotite granite occur locally. Age is Early Silurian or perhaps Ordovician, based on Rb-Sr whole rock ages.

Caesars Head Granite geographically extended to GA. Age is Ordovician(?) to Early Silurian based on preliminary discordant 206Pb-207Pb age of zircons of about 435 Ma (T.W. Stern and J.W. Horton, Jr., unpub. data).
