Abstract
Synopsis: The Beinn an Dubhaich granite intrudes and deforms Cambro-Ordovician limestones and Tertiary dykes in west-central Strath on Skye. The limestones were intensely deformed by radial compression from a centre at the west end of the present granite outcrop, presumably due to the forceful intrusion of an early phase of the granite. Basaltic dykes associated with the Tertiary igneous centres of Skye were deformed co-axially with the earlier deformation in the limestones. Chilled boudin necks in the dykes suggest that this deformation took place before consolidation of the basalt. This was followed by passive intrusion of the main mass of the granite as a large, possibly funnel-shaped sheet.
