The National Uranium Resource Evaluation (NURE) program was begun in the spring of 1973 to evaluate domestic uranium resources in the continental United States and to identify areas favorable for uranium exploration. The significance of the distribution of uranium in natural waters and sediments will be assessed as an indicator of favorable areas for the discovery of uranium deposits. This paper is oriented primarily to the discussion of stream sediments. Data for the Challis 1/sup 0/ x 2/sup 0/ NTMS quadrangle will be used for specific samples of NURE data processing. A high-capacity neutron activation analysis facility at SRL is used to determine uranium and about 19 other elements in hydrogeochemical samples. Evaluation of the areal distributions of uranium ratios demonstrate that most of the high U/Hf, U/Th and U/(Th + Hf) ratios occur scattered throughout the western two-thirds of the quadrangle. Most of the higher ratio values are found in samples taken at sites underlain by granitic rocks of the Idaho batholith or Tertiary-age plutons.
