Caption: Dolomite from the Durness Limestone, Sarsgrum, Eriboll, Sutherland.
Description: Sarsgrum is two and a half miles south-west of Durness and contains a number of exposures of Cambro-Ordovician dolomites. This specimen shows veining. British Geological Survey Petrology Collection sample number MC 7503. Mottled dolomites of a high grade belonging to the Sailmhor Group form a rocky bluff at Sarsgrum. A chemical analysis from this locality yielded 52.7 per cent calcium carbonate and 44.4 per cent magnesium carbonate. Less than half a mile north of Sarsgrum and five-sixths of a mile south of Keodale, a section of the Eilean Dubh Group can be seen along the course of a small stream flowing into the Kyle of Durness. A chemical analysis from this locality yielded 49.3 per cent calcium carbonate and 40.3 per cent magnesium carbonate.
