DIVISION OF GEOLOGY AND MINERAL RESOURCES

Isle of Wight County, Virginia

There are eight active mine permits in Isle of Wight County which are licensed to produce sand, and one active mine permit licensed to produce marl. In 2006, 1,048,284 tons of sand were produced in Isle of Wight County. Based on the Virginia Division of Geology and Mineral Resources (DGMR) Publication 174, Digital Representation of the 1993 Geologic Map of Virginia, the sand was apparently produced from alluvium, the Shirley Formation, the Charles City Formation, and the Yorktown Formation of the Chesapeake Group. The attached geologic map indicates where these formations are exposed and accessible. From 2001 to 2005, the Isle of Wight Materials Company, Inc., produced 299,908 tons of marl. Based on the DGMR Digital Representation of the 1993 Geologic Map of Virginia, the marl was apparently produced from the Sedgefield Member of the Tabb Formation. There was no reported production of marl in 2006. Information on these mining operations is available from the Virginia Division of Mineral Mining in Charlottesville, Virginia (434-951-6310).

There are 42 identified sand and gravel pits, 1 gravel pit, two marl pits, and one lime quarry that are inactive or historical in Isle of Wight County. Based on the DGMR Publication 174, Digital Representation of the 1993 Geologic Map of Virginia, the historical sand and gravel pits are located in the Sedgefield Member of the Tabb Formation and the Windsor Formation, in addition to alluvium, the Charles City Formation, the Shirley Formation and the Yorktown Formation. The attached geologic map indicates where these formations are exposed and accessible. The coquina facies of the Yorktown Formation was used as a source of calcium carbonate for cement manufacture. Also, the Battery Park Fish and Oyster Company calcined oyster shells collected from what is now named the Sedgefield Formation, near the confluence of the Pagan and James rivers, to produce lime. In addition, they provided shells that were used for sub-base in highway construction (Coch, 1968). Two historical marl pits are located on Lake Tormentor; the marl was produced for agricultural purposes (Johnson, 1976).

Six samples of clay materials collected in Isle of Wight County were tested between 1957 and 1978, and 5 were found suitable as raw materials for the manufacture of brick, drain tile, structural clay products, or lightweight aggregate (Johnson and Tyrrell, 1967; Sweet, 1982). The samples with potential for the manufacture of brick were taken north of Rescue, southwest of Rushmere, north of Franklin Municipal Airport, and southeast of Smithfield.
