Hydrogeochemical and stream sediment reconnaissance basic data for Scottsbluff NTMS Quadrangle, Nebraska and Colorado
Results of a reconnaissance geochemical survey of the Scottsbluff Quadrangle are reported. Field and laboratory data are presented for 567 groundwater and 402 stream sediment samples. Statistical distributions and symbol plots for uranium and possible uranium-related variables are enclosed. A generalized geologic map and a producing horizon map for the survey area are provided. Pertinent geologic factors which may be of significance in evaluating the potential for uranium mineralization are briefly discussed. Groundwater data indicate that uranium concentrations above the 85th percentile occur primarily in the northwestern corner of the quadrangle, and that uranium in groundwater is associated with high values for specific conductance, boron, calcium, lithium, magnesium, sodium, strontium, sulfate, and total alkalinity. Water in this area is produced primarily from the White River Group. Weighted sum models for groundwater of the Scottsbluff Quadrangle delineate areas in the northwestern section in which uranium is associated with variables deemed favorable for economic mineralization. Stream sediment data indicate that uranium values above the 85th percentile occur in three areas in the western portion of the quadrangle and that soluble uranium is associated with high values for uranium by neutron activation, iron, lithium, magnesium, manganese, phosphorus, scandium, yttrium, and zinc. Sediment with high soluble uranium concentrations was derived primarily from the Hemingford, Arikaree, and White River Groups.
