Radiometric and petrographic results for samples from drill holes GM-1 and GM-2, Granite Mountains, Wyoming

All conclusions reached in this paper are tentative. The volume of rock sampled by drill holes GM-1 and GM-2 is small compared to the outcrop area. Analyses of rocks collected over the entire outcrop area are currently underway to test the conclusions reached for the drill-core samples. Analyses are also being made on drill-core samples from the east end of the Granite Mountains. Our preliminary evaluation of the data from drill cores GM-1 and GM-2 suggests that statistical evaluations of uranium, thorium, and potassium data may be sufficient to indicate uranium mobility in granitic rocks. It is possible that uranium mobility may be suggested by a large standard deviation relative to the mean uranium content, a non-Gaussian distribution of uranium among samples as indicated by such measurements as skewness and kurtosis, and a failure of uranium values to correlate with either thorium or potassium contents
