| Caption: | Limestone from Berry, Scalloway, Shetland. |
| Description: | A grey coarsely crystalline limestone with occasional micaceous films from Berry, half a mile north of Scalloway, Shetland. The specimen has banded white calcite veins with a biotite augen, an eye-shaped feature. BGS Sample SL 185. British Geological Survey Petrology Collection sample number MC 7619. Belonging to the Tingwall Limestone it consists essentially of metalimestone with intricately sutured grains of calcite, about 0-5 mm across, together with about 25 per cent of quartz in grains which are usually distributed singly among the calcite but also form small aggregates with or without associated muscovite. The quarry is in the western branch of the limestone. The outcrop of limestone is about 100 yards wide, and the dip is west at 70 degrees to 80 degrees. Analysis of the specimen gives the following percentages (S.L. 185): calcium carbonate, 82.37, magnesium carbonate, 1.78, insoluble residue 13.19. |
