NURE Aerial gamma-Ray and Magnetic Reconnaissance Survey of Maine and Portions of New York. Volume I. Data Acquisition, Reduction and Interpretation. Final Report

摘要

As part of the Department of Energy (DOE) National Uranium Resource Evaluation Program, Carson Geoscience Company has performed a rotary-wing high sensitivity radiometric and magnetic survey of the State of Maine and of the Binghamton, Ogdensubrg and Utica 1:250,000 scale quadrangles in New York State. The area surveyed consisted of approximately 14,424 line miles. The survey was flown with a Sikorsky S58T helicopter equipped with a high sensitivity gamma ray spectrometer which was calibrated at the DOE calibration facilities at Walker field in Grand Junction, Colorado, and the Dynamic Test Range at Lake Mead, Arizona. The radiometric data was processed to compensate for Compton scattering effects and altitude variations. The data was normalized to 400 feet terrain clearance. The reduced data is presented in the form of stacked profiles, standard deviation anomaly plots, histogram plots and microfiche listings. The profiles, anomaly maps and histograms are presented in the individual quadrangle reports. The results of the geologic interpretation of the radiometric data for each quadrangle is presented as individual chapters of this narrative report. (ERA citation 06:034341)
