| Description: | A specimen of the Jurassic Great Estuarine Series limestone that has been contact metamorphosed by proximity to the nearby granophyre. The specimen is from Allt Eoghainn, 200 yards south of the old main road, Strollamus, Skye, Invernessshire. BGS Sample SL 239. British Geological Survey Petrology Collection sample number MC 7633. It is a patchily grey and white altered limestone, the grey part effervescing freely with cold dilute HCl, while the white part is insoluble and shows the fibrous character of wollastonite. Shelly limestones and shales of the Great Estuarine Series are exposed in the Allt Eoghainn from 200 yards to 300 yards south of the old road, with dip south-east at 42 degrees to 65 degrees but are rather thin. Some of the limestone beds appear to be of good quality. Stone nearest the granophyre intrusion is highly altered, the analysis (S.L. 243) showing CaO 40.57 per cent; MgO 0.30, carbon dioxide, 11.22, insoluble residue 40.55 per cent. |
