Abstract
New occurrences of kyanite-bearing schists in the Moine Series in southern Ross-shire demonstrate the order of appearance of the typomorphic minerals staurolite, kyanite, garnet, and sillimanite, and are of significance in elucidating the relationship of regional metamorphism to orogenesis. The scarcity of kyanite in the Northern Highlands is the result of both isochemical and allo-chemical effects, and its distribution is compared with that of its polymorphs andalusite and sillimanite.
