[email protected]) Abstract: The Ballachulish region of the SW Highlands of Scotland was the focal point of a famous debate in the 1920s between Sir Edward Battersby Bailey and Professor Cecil Edgar Tilley concerning the identity, geometry and timing of development of metamorphic zones in the SW Highlands. New mineral assemblage data, microstructural observations, and rock and mineral compositional data are combined with phase equi- librium modelling to reassess the metamorphism in this area.
