The Stoer Group is a sequence of Mesoproterozoic sedimentary rocks that outcrops on the peninsula of Stoer, near Assynt, Sutherland. The dominant lithology is sandstone with breccias and conglomerates developed near the base It is subdivided into three formations. It lies unconformably on the underlying Archaean to Paleoproterozoic age gneisses of the Lewisian complex and is in turn unconformably overlain by the Neoproterozoic Torridon Group.[2]
