Summary

Clearly boudined and folded igneous sheets occur in Durness Limestone on the south side of the Tertiary Ben an Dubhaich granite. Obvious Tertiary dykes in nearby Mesozoic rocks are not deformed at all, nor has such deformation been described previously from the Caledonian activity in the Cambro-Ordovician of the north-west Highlands. Its appearance here does fit Clough's description (in Peach et al. 1907) of an unusually strong Caledonian penetrative deformation in the Strath Limestone, while the fact that all but one of the sheets are dolerites, a rock not elsewhere known from the Cambro-Ordovician but typical rather of the Tertiary activity for which Skye is famous, and that the other is a two feldspar porphyry very like the Ben an Dubhaich granite, point to the possibility of Tertiary deformation.
