Caption: Brucite marble from the Torran area, Skye, Invernessshire.
Description: The Cambrian - Ordovician Durness Limestone in the Torran area is, in the south, in contact with the Beinn an Dubhaich granite and is markedly metamorphosed in its vicinity. British Geological Survey Petrology Collection sample number MC 7527. The main rock type in the aureole is forsterite marble though brucite marble occurs near the granite contact at Cnoc Dubh. The Durness Limestone has been altered by thermal metamorphism. The rocks in the contact-aureole are all grey and white marbles, often coarsely crystalline in appearance. In thin section they are seen to be recrystallized rocks, generally containing metamorphic minerals and may be described as forsterite-brucite-diopside marbles.
