| Caption: | Limestone from Turnalt Quarry, Argyllshire. |
| Description: | A very fine-grained dark grey and banded limestone from the Turnalt Quarry, Argyllshire. The limestone belongs to the Shira Limestone of Dalradian Supergroup (Precambrian) age. BGS Sample SL 124. British Geological Survey Petrology Collection sample number MC 7598. The only occurrence of the Shira Limestone of economic importance is this locality at Turnalt. It was quarried and burnt on a small scale for local requirements. The stone is a fine-grained, bluish limestone with thin phyllitic partings and subordinate quartz, showing on analysis: calcium carbonate 86.04 per cent, magnesium carbonate 2.69 per cent, insoluble residue 10.64 per cent. There is a general dip in a direction east 25 degrees south at 70 degrees, but the strata are repeated by a small anticline and syncline on the east side of the quarry. The limestone is about 15 feet thick stratigraphically, but owing to repetition by the folds just mentioned shows a width of 30 feet in the quarry-face. The reserves are very considerable to the north-north-east. |
