by C.R. Berquist, Jr., color map with text, one sheet, scale 1:24,000, 1988. This map shows the bedrock geology and surficial deposits of the Callands and Sandy Level 7.5-minute quadrangles and includes a discussion of the area’s stratigraphy, structure, and economic geology. These quadrangles are located in the Virginia Piedmont province and are almost entirely within Pittsylvania County, with only the northwest corner of the Sandy Level quadrangle in Franklin County. Precambrian to Paleozoic igneous and metamorphic rocks, Paleozoic to early Mesozoic cataclastic rocks, Mesozoic diabase dikes, and recent terrace and alluvial deposits are mapped in these quadrangles. Abandoned barite and iron ore mines, prospects, and rock repository locations are plotted on the map. The map also includes several cross-sections.
