| Description: | A specimen of fine-grained dark grey limestone with coarse white calcite crystals in a vein from Port Ramsay, Lismore, Argyllshire. The rock is part of the Dalradian Supergroup (Precambrian) Lismore Limestone. BGS Sample SL 88. British Geological Survey Petrology Collection sample number MC 7600. The island of Lismore consists mainly of limestone with partings and subordinate beds of black graphitic schist and igneous intrusions. The limestone varies considerably in composition. In the past the Lismore Limestone was quarried and burnt at numerous localities. The most important working was a large quarry situated 700 yards north-east of Port Salen (Sailean). Limestone has also been worked in the past in a quarry just north of Port Ramsay. On analysis it showed: calcium carbonate 87.17 per cent, magnesium carbonate 0.25 per cent and insoluble residue 11.25 per cent. |
