Integration of NURE and other data sets, southwest Montana and northeast Idaho: an orientation study to characterize mineralized environments. National Uranium Resource Evaluation
Mineralized environments in the Dillon, Butte, Hamilton, and Elk City 1/sup 0/ x 2/sup 0/ NTMS Quadrangles were identified and characterized from the National Uranium Resource Evaluation (NURE) Hydrogeochemical and Stream Sediment Reconnaissance and Aerial Radiometric and Magnetic Survey data, folio data, and other data sets used in this study. Methods applied to reconnaissance for uranium during the NURE program were used successfully in this project to recognize and delineate locales that have mineral-resource potential. These methods included preparation and interpretation of maps of geochemical, aerial radiometric, and aeromagentic data, as well as interpretation of univariate and multivariate statistical analyses of NURE data sets. Data interpretations were conducted by a contingency approach that puts a variety of statistical and cartographic tools at the disposal of the geologist. These tools were applied selectively to the data until the geochemical and geophysical signature of an anomalous locale was described and characterized to the geologist's satisfaction. Ten areas known to be mineralized were described as type localities and used to calibrate the geochemical and geophysical models employed in the study. Other areas exhibiting anomalous geochemical and (or) geophysical characteristics were analogized to the type localities. Thirty anomalous areas were delineated during this study; 17 of the 30 are believed to warrant further investigation. Three locales contain Tertiary intrusive bodies that were delineated on the basis of their characteristic signatures and trace-element contents. 5 figures, 10 tables.
