| Description: | Carboniferous Murrayshall (Hurlet) Limestone from the Murrayshall Limeworks, Cambusbarron, 14 miles south-west of Stirling. BGS Sample SL 159. British Geological Survey Petrology Collection sample number MC 7615. A black, compact, fine-grained limestone showing conchoidal fracture; specks of pyrite and crinoid columnals are sparsely distributed. Composed of a turbid, very fine-grained matrix of calcareous fossil debris, calcite granules, and probably some clay, in which are numerous fragmentary large and small shells, crinoid columnals, foraminifera, spines and polyzoa. The quality of the Murrayshall Limestone (S.L. 159) is shown by the following percentage figures: calcium carbonate 86.56, magnesium carbonate 2.28, insoluble residue 8.18. The Murrayshall (Hurlet) Limestone crops out on the west side of Gillies Hill, south of Cambusbarron, and underlies the Stirling dolerite sill throughout the area. The old workings were entered by an adit driven from Cambusbarron southwards to cut the limestone through an east-west upthrow fault. |
