Summary:
Informal term Shores melange has been used for parts of the belt which Bland and Blackburn (1980) referred to as the Shores Complex. [Bland and Blackburn do not formally name the unit though it is discussed and illustrated in several figures.] Unit has been previously mapped as part of the Evington Group by Smith and others (1964) and by Brown (1969). The Shores lies between Cambrian Chopawamsic on the east, Evington Group and Hardware Metagraywacke on the west. Fig. 2 shows areal extent of unit in central VA. Consists chiefly of complexly and polydeformed magnetite-rich metagraywacke, siliceous schist and phyllite, numerous greenstone sheets and lenses, and occasional metagabbro and ultramafic masses. Includes Diana Mills body, the largest of the mafic-ultramafic bodies in Complex.
