Gray and white quartzites occur in association with metamorphosed limestones and garnetiferous mica schists near Blair Atholl, northeast Scotland. The quartzites are irregular in texture, with quartz frequently occurring in radial aggregates, and are quite different from quartzites normally found in the Dalradian series. It is suggested that they were derived from chert or jasper, rather than sandstone.
