Abstract
South of Loch Laxford, basic and ultrabasic rocks overlying migmatitic gneisses and underlying schists of supracrustal origin, occupy a NW trending late Scourian synformal trough. The basic and ultrabasic outcrops are parts of a continuous sheet-like body now having a maximum thickness of 400 m and extending along strike for at least 12 km. Although the body has suffered the effects of the granulite facies metamorphism, still preserved in little-deformed portions of the sheet are lithological sequences, textures and minerals characteristic of a layered cumulitic igneous body.
