Description: A red fine-grained brittle limestone with sub-conchidal fractures. The most extensive outcrop of the Cambro-Ordovician Durness Group, formerly known as the Durness Limestone occurs in the Durness area. This specimen is from the Coinstone Skerry. British Geological Survey Petrology Collection sample number MC 7507. The Durness Group consists of c. 1500 feet of bedded dolomites with minor limestones and magnesian limestones. The rocks dip towards the east-south-east at angles from 12 degrees to 30 degrees. The limestones of Group V and VI, the Balnakiel and Croisaphuill Groups are confined to two comparatively narrow outcrops. A 300 yard belt running southwards from the coast at Balnakiel and a quarter of a mile east of Sarsgrum-Drochaid Mhor road.
