[en] As part of the Department of Energy (DOE) National Uranium Resource Evaluation (NURE) Program, LKB Resources, Inc. has performed a rotary-wing, reconnaissance high sensitivity radiometric and magnetic survey in the Blue Ridge area of Virginia, North Carolina, South Carolina, Kentucky, and Tennessee. Five (5) 1:250,000 scale NTMS quadrangles (Greensboro, Winston-Salem, Johnson City, Knoxville, and Charlotte) were surveyed. A total of 15,753 line miles (25,347 kilometers) of data were collected utilizing a Sikorsky S58 and S58T helicopter. Traverse lines were flown in an east-west direction at 3.0 mile (4.8 kilometer) spacing, with tie lines flown in a north-south direction at 12 mile (20 kilometer) spacing. The data were digitally recorded at 1.0 second intervals. The NaI terrestrial detectors used in this survey had a total volume of 2,154 cubic inches. The magnetometer employed was a modified ASQ-10 fluxgate system. This report covers the Greensboro, Winston-Salem, and Johnson City NTMS 1:250,000 scale quadrangles. The Knoxville and Charlotte NTMS 1:250,000 scale quadrangles are covered in a separate report. The radiometric data were normalized to 400 feet terrain clearance, and are presented in the form of computer listings on microfiche and as stacked profile plots. Profile plots are contained in Volume II of this report. A geologic interpretation of the radiometric and magnetic data is included as part of this report
