Abstract
Synopsis The metamorphic history of these Moine and Lewisian rocks in the Moine nappe of Skye is as complicated as the structural history, one of the principal difficulties being the recognition of equilibrium assemblages. Detailed work on an important garnet-hornblende-biotite-epidote assemblage in gneissic rocks indicates that the highest metamorphism was probably of lower almandine amphibolite fades and that it occurred early in the structural history of the area. Later retrograde changes took place in schistose rocks nearer the Moine thrust plane. Co-existing chlorite-actinolite assemblages, analysed in detail, indicate a metamorphic grade probably not much lower than the almandine amphibolite facies.
