| Caption: | Limestone from Elgol, Skye, Invernessshire. |
| Description: | A specimen of the Jurassic (Great Estuarine Series) Paludina scotia limestone from a coast section 800 yards north of the school at Elgol, Skye, Invernessshire. BGS Sample SL 251. British Geological Survey Petrology Collection sample number MC 7642. The limestone is a dark grey, compact, structureless rock composed of a carbonate-clay groundmass in which the carbonate granules are about 0.002 mm across. There are three calcareous horizons lying close together in the sequence. The lowest is the Cyrena limestone group, about 70 feet thick, and consisting of massive blue, and often crystalline, limestone bands in calcareous sandstone. Above it lies a less massive group of calcareous beds with Ostrea hebridica, thickness, say, 20 feet. A short distance higher in the sequence are the Paludina scotica limestones, about 30 to 40 feet thick, consisting of blue fine-grained smooth argillaceous limestones or cementstones, weathering cream-coloured and alternating with shales and calcareous sandstones. |
