The Clay Sample Collection consists of descriptions of physical and chemical characteristics of Virginia’s potential clay resources. Field sample descriptions include physical appearance, sample interval, and location information. Laboratory analyses included geotechnical tests for plasticity, workability, dry strength, pH, bloating, and firing. For some samples there may also be laboratory results for major, minor, and trace parameters. The collection includes 870 sample records published in DGMR Publications 36, 68, 76; Bulletins 2, 13, 20; and Mineral Resources Report 2, 5, 6, 8, 12, and 13. This collection provides statewide data on potential clay materials resources which could be used for ball clay, floor and wall tile, sanitary ware, absorbents, drilling muds, brick, cement, lightweight aggregate or other possible uses. Laboratory data is generally available only in published reports that are identified for each record.
