Statistical Techniques Applied to Aerial Radiometric Surveys (STAARS): Application of the Huber M-Estimator to Aerial Radiometric Data for the Identification of Host and Source Areas for Uranium Deposits.

摘要

Throughout the aerial radiometric survey portion of the US Department of Energy National Uranium Resource Evaluation (NURE) program, the detection of significantly low or high radioelement values has been an important aid in identifying regions with either higher than expected or lower than expected radioelement concentrations. In this paper, a robust method employing Huber M-estimators has been utilized to analyze aerial radioelement data for significantly high and low values. All possibly significant highs and lows have been mapped spatially to locate geographically those areas that may be favorable as hosts and sources for uranium deposits. The robust Huber method has been automated with all referenced computer programs having been written for a CDC 6600. (ERA citation 07:045815)
