Abstract
Synopsis: Field and textural evidence from a coastal traverse immediately west of Macduff indicates that the main phase of regional metamorphism separates in time the movements which produced the slaty cleavage and folds at Macduff from those which produced the strain-slip cleavage and monoclines on the steep western limb of the Boyndie Syncline. The slaty cleavage of the Macduff Slates is, therefore, thought to be equivalent to the early movements in the rest of the Dalradian; an important conclusion in the light of the recent discovery of Lower Ordovician fossils in the Macduff Slates.
