543The Mineral Industry of Virginia By Leonard J. Prosser~ The value of Virginia's nonfuel mineral production was $264.9 million in 1978 and $309.8 million in 1979. During these years, Virginia's major nonfuel commodities were, in terms of value, cement, kyanite, lime, sand and gravel, stone, and zinc. Other commodities that contributed to the State's mineral economy included aplite, clay, gypsum, lead, and talc. Also, the State's first vermiculite mine began production in 1979. Trends and Developments.—In the 1970's, stone production accounted for approximately 50% of Virginia's total nonfuel mineral production value. Stone output peaked in 1978 at 50.5 million short tons and again in 1979 at 51.1 million short tons. As these record production levels were reached, the State's nonfuel mineral production value surpassed the $300 million mark for the first time. Virginia became the third State in the Nation to produce crude vermiculite when Virginia Vermiculite, Ltd., began operations in 1979. The open pit operation is located about 20 miles east of Charlottesville in Louisa County. Previously, Montana and South Carolina accounted for all domestic vermiculite production. The material, after extraction, is exfoliated and used mostly by the construction industry.
