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 degree x 2 degree Quadrangle,
Tennessee,
North Carolina, and South Carolina. This open-file report is meant to
supplement Bulletin 1979. The Knoxville 1 degree x 2 degree 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.
