Caption: Brucite marble from the Kilchrist area of Skye, Invernessshire.
Description: Dolomite and brucite marble were considered important resources during the Second World War for use as a basic refractory or for the extraction of metallic magnesium. British Geological Survey Petrology Collection sample number MC 7529. Locally, in Assynt and in the Isle of Skye dolomite has been converted into brucite marble, a mixture of calcite and brucite, the hydrous oxide of magnesia, by the natural calcining action of intrusive igneous rocks, followed by hydration. This specimen is from the Kilchrist - Loch Cill Chriosd area of Skye where Cambrian Durness Limestone has been altered by the heat of emplacement of the Beinn an Dubhaich granite.
