Above: Knoxville 1° x 2° Quadrangle geology and mineral deposits. (Click thumbnail for larger view.)
The following geographic information system (GIS) data layers provide a digital format for the map plate in Bulletin 1979 (Robinson et al., 1991), “Bedrock Geology and Mineral Resources of the Knoxville 1 ° x 2° Quadrangle, Tennessee, North Carolina, and South Carolina.” This open-file report is meant to supplement Bulletin 1979. The Knoxville 1° x 2° quadrangle spans the Southern Blue Ridge physiographic province at its widest point from eastern Tennessee across western North Carolina to the northwest corner of South Carolina. The quadrangle also contains small parts of the Valley and Ridge province in Tennessee and the Piedmont province in North and South Carolina. The bedrock geology for the coverage area is provided as a polygon coverage with bedrock unit information included. Mineral resources and geologic faults are provided as point and line files, respectively, to overlay the geology coverage. Detailed geologic information is provided in the attribute tables for these files, and .avl legend files are provided.
