Pg. 783-786, 787. Cherryville quartz monzonite. A monazite-free rock in which three varieties have been recognized: the commonest, a gray even-grained massive to faintly gneissic muscovite-biotite rock; a muscovite-quartz monzonite; and a quartz-biotite. Unit was included in Whiteside granite as mapped by Keith and Sterrett (USGS Bull. 660-D, 1931); hence, Whiteside granite is herein restricted to area of its type locality. Considered to be very late Paleozoic and younger than Toluca quartz monzonite (new).
Named from exposures near Cherryville, Gaston Co., western NC.

Pg. 566. Cherryville quartz monzonite. A probable Devonian age (about 285 Ma) was obtained on a sample of monazite from the Cherryville quartz monzonite.

[GNC remark (ca. 1960, US geologic names lexicon, USGS Bull. 1200, p. 752): The USGS currently designates the age of the Cherryville as Mississippian(?) to Permian(?) on the basis of a study now in progress. (See Overstreet and Bell, 1965.)]

Pg. 68, 89 (geol. time scale), 91 (table 7), 94 (table 8), 109-110. Cherryville Quartz Monzonite. Age changed from Devonian(?) --to-- Mississippian(?) 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.)

Age of the Cherryville changed to Late Mississippian on the basis of Kish's (1977) Rb-Sr whole rock age of 341+/-11 Ma.

Name Cherryville Quartz Monzonite changed to Cherryville Granite to conform to IUGS classification and nomenclature of igneous rocks. Rb-Sr whole rock age is 351 +/-10 Ma based on data from Kish (1983, unpub. Ph.D thesis). Age is Mississippian.
