Description:
A gamma-ray survey was made of the radioactivity of exposed rocks in the dry valleys in order to evaluate the uranium resource potential of the ice free outcrops. The geology of the study area, counting apparatus, flight operations, counter calibration, results, other potential resources, a C-130 flight test, and glaciological applications of gamma-ray spectrometry are described. Uranium bearing pegmatites were found and other potential mineral resources, i.e. fluorite were discovered. The Beacon Group rocks which were through to be the most promising host beds in the area, showed no significant concentrations of uranium. The trachyte volcanics and intrusives contained high levels of radioactivity, though no substantial localizations of uranium were found. The pegmatites of the lit par lit sequence at Mt. Dromdary and Roaring Valley are the most promising occurrences. Results also indicate that statistically significant variations in radioactivity can be detected in snow layers using gamma-ray detectors.
