Caption: Limestone from Durness, Sutherland.
Description: Limestone from Durness, Sutherland. The Durness area has outcrops of all seven stratigraphic subdivisions of the Cambro-Ordovician Durness Limestone or more correctly, Durness Formation. British Geological Survey Petrology Collection sample number MC 7445. The Durness Formation is a series of limestones, dolomitic limestones, calcareous dolostone and dolostone (i.e. fine-grained carbonate rock grading from pure limestone to pure dolomite.) A few minor variants exist such as cherty limestone and chert nodules at some horizons. There is evidence in some units of authigenic dolomitization of limestone e.g. dolomitized fossils and oolites, though some of the Durness sequence comprises primary dolomite.
