在洛赫拉克斯福德南部，基性和超基性岩覆盖在混合片麻岩和下伏的表壳成因的片岩上，占据了一个西北走向的晚斯库里亚同形槽。基性和超基性露头是一个最大厚度为400 m的连续板状体的一部分，沿走向沿着至少12 km。虽然该岩体受到麻粒岩相变质作用的影响，但在岩片的小变形部分仍保留着层状堆晶火成岩体的岩性序列、结构和矿物特征。
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.
