| Description: | Brucite marbles of the penatite and predazzite type are found at several localities in Skye, particularly in the Kilchrist and Loch Cill Chriosd district where they have been formed by the thermal action of the Beinn an Dubhaich granite and the Cambrian Durness Limestone. British Geological Survey Petrology Collection sample number MC 7530. In the 1940s brucite marble was successfully employed in America as a substitute for magnesite in the manufacture of basic refractory linings. Because of this there was renewed interest in finding brucite marble deposits in Great Britain during the Second World War. Brucite is magnesium oxide. It belongs to the hexagonal crystal system, it is a soft mineral, only 2.5 on Moh's scale of hardness. It can be colourless, green or blue in colour. |
