Abstract

Trigonal paragonite, which, to the writer's knowledge, has never been reported to occur at any locality, has been found to occur with kyanite at two localities on the western part of the Piedmont of Virginia. The identity of the mica from these localities was determined in the early stages of an investigation of the mineralogy and chemistry of mica-kyanite associations. This investigation, which is being carried on currently, was initiated because it was noted that, in Virginia, white mica(s) are typically associated with light blue or nearly white kyanite(s), green mica(s) are associated with darker blue kyanite(s), etc.
