From abstract: Results of a reconnaissance geochemical survey of the Eau Claire Quadrangle, Wisconsin; Minnesota are reported. Field and laboratory data are presented for 565 groundwater samples, 680 stream sediment samples, and 667 stream water samples. Statistical and areal distributions of uranium and other 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.

From introduction: This folio was compiled to facilitate the use of groundwater as a sampling medium to aid in exploration for hitherto undiscovered deposits of uranium in the subsurface rocks of Minnesota. The report consists of the following sheets of the hydrogeologic map of Minnesota: 1) map of bedrock hydrogeology, 2) generalized cross sections of the hydrogeologic map of Minnesota, showing both Quaternary deposits and bedrock, 3) map of waterwells that penetrate Precambrian rocks in Minnesota. A list of these wells, showing locations, names of owners, type of Precambrian aquifers penetrated, lithologic material of the aquifers, and well depths is provided in the appendix to this report.

Tables displaying index to statistical analysis and reduced data values for each quadrangle in the survey area.

From abstract: The objective of the work was to define areas showing surface indications of a generally higher uranium content where detailed exploration for uranium would most likely be successful.

First volume of a report documenting a high-sensitivity airborne radiometric and magnetic survey of four quadrangles in Wisconsin, Minnesota, and Michigan including documentation about data collection and analysis.

During the months of August and September, 1979, geoMetrics, Inc. collected 12,415 line miles of high sensitivity airborne radiometric and magnetic data in adjoining portions of South Dakota and Minnesota over seven 1 by 2 degree NTMS quadrangles (Thief River Falls, Grand Forks, Fargo, Milbank, Watertown, New Ulm, and St. Cloud). All radiometric and magnetic data were fully corrected and interpreted and are presented as eight volumes.

This report discusses aeromagnetic data that was obtained from uranium anomalies discovered in the Watertown quadrangle of South Dakota and Minnesota.
