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

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.

The following report is the first volume documenting the high sensitivity airborne radiometric and magnetic data taken during the month of April, 1980, by EG&G geoMetrics in the western areas of South Dakota. This volume contains survey description, specifications, data processing methods, interpretation methods, and regional geologic review.

This report is one part of the second volume containing data on the Nemo Detail area in South Dakota. This volume contains the detailed geologic summary, interpretation report, standard deviation maps, pseudo-contour maps, interpretation map, flight line and geologic base map, individual corrected profiles, computer map unit histograms and statistical tables.

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 Milbank quadrangle of South Dakota, North Dakota, and Minnesota.

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