The sedimentary rocks of Sleat of Skye,are represented by Torridonian sandstones and shales and Cambrian quartzites and dolomites with some dolomitic shales and shales. The upper part of the Torridonian,consists of a thick pile of sandstones, poorly stratified and in places strongly contorted. Grain size varies and often shows a bimodal fequency distribution.The major constituents include quartz, feldspars mica and sericitic or clayey material, ore and lithic fragments. The lower part of the Torridonian, contains numerous bands of shale, which in Skye, appear at definite stratigraphical positional, thus making subdivision possible. These shales and sandy shales display well developed statification and show occasional ripple bedding.In places features of flowage and loading may be observed. The Cambrian quartzites overlie unconformably the Torridonian the lower part is strongly false bedded and the upper contains numerous small tubes, believed to have resulted from the burrowing; action of worms. This rock unit is followed by the thin bands of Seroulite Grit of orthoquartzitic composition and icoid Shales. The uppermost part of the succession consists of the Durness Limestones,represented in this area by fine to coarse grained dolomites with numerous small scale sedimentary structures. Some parts of the area are covered by breccias believed to be of sedimentary origin. The ground has been affected by at least three periods of folding,two of which were accompanied also by sets of minor folds.Strong thrusting subdivided the area into several slices, the structures may however be correlated across the thrust planes.
