| Caption: | Brucite marble from 800 yards north-north-west of Camas Malag, south of Torran, Skye, Invernessshire. |
| Description: | The brucite marble has formed due to the contact metamorphism (and possibly regional) of the Cambro-Ordovician Durness dolomites by the intrusion of the granite of Beinn an Dubhaich. This specimen is whitish in appearance. British Geological Survey Petrology Collection sample number MC 7525. The contact aureole is generally several hundred yards wide. The rocks in the contact-altered areas are all grey or white marbles, mostly forsterite marbles. Brucite marbles also exist though they are rarely pure, the marbles containing brucite and forsterite. Brucite is a magnesium hydroxide mineral found commonly in the metamorphism of dolomites where it forms at the expense of periclase, magnesium oxide. |
