The central Virginia volcanic-plutonic belt: An island arc of Cambrian(?) age
Louis Pavlides
1981, Professional Paper 1231-A
Pre-Ordovician, probable Early Cambrian metavolcanic and somewhat younger meta-intrusive rocks form a linear belt in the central Virginia Piedmont. On the basis of the geologic and geochemical features of these rocks in the Fredericksburg area, and insofar as this area is representative of the entire belt, it is concluded that...
