Summary:

Yorkville granite. Dark-gray coarse-grained granite. Intrusive into Roan gneiss. Believed to be younger than Whiteside granite. Age is Late Carboniferous(?).
[Named from exposures at Yorkville (also called York), York Co., northwestern SC. Extends to southern NC.]

Summary:

Yorkville granite revised to Yorkville quartz monzonite. Age is Early Mississippian(?) in this report. [Yorkville granodiorite originally proposed in this report, but rejected until composition was determined. Authors finally agreed to usage of quartz monzonite in March 1957. Age modification based on zircon age determinations.]

Summary:

Pg. 89 (geol. time scale), 93 (table 7), 94 (table 8), 108-109. Yorkville Quartz Monzonite. Age changed from Early Mississipian(?) --to-- Permian on basis of Lead-alpha age determination. (Authors follow revised time scale of Holmes, 1959, Edinburgh Geol. Soc. Trans., v. 17, pt. 3, p. 183-216.)

Summary:

Coarse-grained, porphyritic, gneissic biotite granite in Kings Mountain belt mapped as Yorkville by Espenshade and Potter is renamed High Shoals Granite to distinguish it from non-foliated granites like the type Yorkville near York, SC.

Summary:

Yorkville Quartz Monzonite abandoned because granites mapped previously as Yorkville, including the type Yorkville near York, SC, are redefined here as Churchland Plutonic Suite, or as High Shoals Granite by Horton (1984).
