The availability of geological mapping is a critical component of any mineral resource identification program. Comparison of the population growth map and the geologic mapping activity map directly above shows that the U.S. Geological Survey is responsible for much of the rapidly developing areas in Virginia. The USGS and DMR are are working together in several of the USGS areas. At the present time, the time commitment of the USGS to complete this work is uncertain. Other states have a wide range of programs involving identification of mineral resources.
Some states attempt to classify land according to some measure of mineral resource potential.
The Division is compiling a computer data base of known mineral occurrences, locations of previous mining sites and sample collection sites. This data base includes the location, the commodity type, chemical analysis data, and reference to further information. By using appropriate zoning counties may be able to preserve crushed stone, sand and gravel reserves that will allow cost-effective economic development in the future. Mineral and aggregate companies who will use this data to guide future siting of quarries and mines. Consultants who will access this data to facilitate work for their industrial or governmental client.
