"Results of a reconnaissance geochemical survey are reported for the Sioux City Quadrangle, Nebraska; Iowa; South Dakota. Statistical data and areal distributions for uranium and uranium-related variables are presented for 119 groundwater and 542 stream sediment samples. Also included is a brief discussion on location and geologic setting."

This report presents field and laboratory data for 567 groundwater samples and 560 stream sediment samples collected from the Fremont quadrangle in Nebraska and Iowa.

"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)

"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)

From abstract: Results of a reconnaissance geochemical survey of the Lincoln Quadrangle are reported. Field and laboratory data are presented for 577 groundwater and 754 stream sediment samples. Statistical and areal distributions of uranium and possible uranium-related variables are displayed. A generalized geologic map of the survey area is provided, and pertinent geologic factors which may be of significance in evaluating the potential for uranium mineralization are briefly discussed.

"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 that may be of significance in evaluating the potential for uranium mineralization are briefly discussed."
