CommentAccording to Mauger and others 1965, the geologic relation of the Silver Bell Mountains show that the volcanic rocks nos. 8, 9, 9a are older than the monzonite nos. 3, 5, 7 which are dated as 65.9 my, 66.3 my, and 67.1 respectively, and they suggest that argon loss is responsible for the anomalous younger dates.
