Documentation outlining characteristics of field data samples taken in the O'Neill quadrangle.

Data gathered at stream sediment sites in the O'Neill quadrangle, including applicable water chemistry measurements (e.g., pH, conductivity, alkalinity) and elemental analyses.

Data gathered at well water sites in the O'Neill quadrangle, including applicable water chemistry measurements (e.g., pH, conductivity, alkalinity), physical measurements (e.g., temperature, well description, scintillometer readings), and elemental analyses.

"Results of a reconnaissance geochemical survey of the O'neill Quadrangle are reported. Field and laboratory data are presented for 23 groundwater and 292 stream sediment samples. Statistical distributions and symbol plots for uranium and possible uranium-related variables are enclosed. A generalized geologic map and producing horizon map for the survey area are provided. Pertinent geologic factors that may be of significance in evaluating the potential for uranium mineralization are briefly discussed." (from Abstract)

"Results of a reconnaissance geochemical survey of the Broken Bow Quadrangle, Nebraska are reported. Statistical data and aerial distributions for uranium-related variables are presented for 578 groundwater and 442 stream sediment samples. Also included is a brief discussion on location and geology." (from Abstract)
