From abstract: This report is intended to supplement the brief interpretation of geochemical data presented in the "Hydrogeochemical and Stream Sediment Detailed Geochemical Survey for the Edgemont South Dakota; Wyoming" report (Butz, et al, 1980).

The following report provides results from a geochemical survey for the Hot Springs quadrangle, South Dakota. Field and laboratory data are presented for 340 groundwater and 394 stream sediment samples.

Final report documenting a high-sensitivity airborne radiometric and magnetic survey of the Rapid City quadrangle including the survey description, specifications, data processing methods, interpretation methods, and regional geologic review.

The following report presents results of the Edgement detailed geochemical survey. Field and laboratory data are presented for 109 groundwater and 419 stream sediment samples.

The following report gives detailed results of the geochemical survey taken in Buffalo-Lignite, South Dakota. Field and laboratory data are presented for 163 groundwater and 660 stream sediment samples collected within the Custer and Slim Buttes project areas.

Final report regarding the National Logging Program for the National Uranium Resource Evaluation

"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 are reported of a reconnaissance geochemical survey of the Lemmon quadrangle, South Dakota. Field and laboratory data are presented for 565 groundwater and 531 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 are briefly discussed which may be of significance in evaluating the potential for uranium mineralization."

This report provides the results of analyses of the airborne gamma radiation and total magnetic field survey flown for the Martin quadrangle in South Dakota.

Final report documenting a high-sensitivity airborne gamma radiation and magnetic field survey of the Pierre National Topographic Map segment (NL 14-10 quadrangle) including a description of the program and results with the flight line profile data and statistical analysis results.
