Caption: Brucite marble from Ledbeg, Assynt, Sutherland.
Description: In Assynt, typical brucite marbles are found in the Ledbeg River about half a mile east-south-east of Loyne shepherd's house. British Geological Survey Petrology Collection sample number MC 7516. The rocks are medium grained, nearly white in colour and consist of calcite and brucite together with a little dolomite. This specimen is quite coarsely crystalline. The brucite forms small aggregates from 0.1 mm. to 1 mm. in diameter. The large grains are mostly rounded in outline but the smaller ones are often square, triangular or hexagonal. Calcite and dolomite are usually present in roughly equal proportions and form irregular crystals of somewhat larger size than the brucite.
