The paper is concerned with one of the marginal parts of the Laxfordian complex of the Lewisian of north-western Scotland where the older Scourian complex (c. 2500 million years) was reactivated during the Laxfordian orogeny (c. 1600 million years). The effects of Laxfordian deformation are discussed with reference to the distortion of Scourian structures and post-Scourian dolerite dykes and to the orientation of newly-developed structures. The arrangement of structures N.E. of the Laxfordian metamorphic front is thought to result from rotation of pre-existing planar elements during compression on north-east-south-west lines, without the development of very large folds. The connection between the style and arrangement of Laxfordian structures and the metamorphic state of the rocks at the time of deformation is illustrated with reference to both local and regional variations, and some implications of the regional changes in the structural pattern are discussed.
