| Caption: | Limestone from Charlestown, Dunfermline, Fifeshire. |
| Description: | A brownish, compact dolomitized limestone, having a crystalline appearance due to the abundance of crinoid plates. The limestone belongs to the Carboniferous Lower Limestone Group, Charlestown main Limestone from West Quarry, Charlestown Quarries, three miles south-west of Dunfermline. BGS Sample SL 276. British Geological Survey Petrology Collection sample number MC 7652. The limestone is composed of fossil debris consisting essentially of crinoidal and polyzoan fragments; subordinate fossil components include shells, spines, foraminifera, siliceous spicules and scarce phosphatic fragments. The thickness of the Charlestown Main Limestone is very variable owing to the development in places of lenticular reef-knoll structure, a thickness of up to 66 ft. being found in the central portion of one of these dome-like masses which occupied the greater part of the worked-out portion of the West Quarry. |
