Single record data listings taken during aerial gamma-ray and magnetic surveys of the Aberdeen quadrangle in South Dakota.

The following report presents results of an airborne high sensitivity gamma-ray spectrometer and magnetometer survey over the Aberdeen quadrangle, South Dakota.

The following report is the second volume in a series of data presenting results of an airborne high sensitivity gamma-ray spectrometer and magnetometer survey over the Aberdeen quadrangle, North Dakota. This volume contains data maps of the results.

Introduction: This is the fifth of a series of reports covering technical progress on the research and development program being performed in connection with the design of the Pathfinder Atomic Power Plant.

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.

From abstract: The uranium mineral uranocircite, a barium uranyl phosphate, occurs in a sandstone channel in the Chadron formation of Oligocene age in the White River Badlands, Pennington County, S. Dak. A vertical section of the basal 1-foot of the channel contains 0. 25 percent uranium. There are also small amounts of metatyuyamunite (?) in the upper part of a freshwater lime stone bed in the Chadron formation and carnotite in chalcedony veins in the overlying Brule formation, also of Oligocene age.
