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.

Final report of the airborne gamma ray and total magnetic field survey for the Sterling quadrangle, Colorado-Nebraska-Kansas. Sections I through IV of this report present information and results associated with this specific survey. Section V gives the data acquisition and the processing procedures.
