| Caption: | Crushed limestone from Onich, Invernessshire. |
| Description: | Crushed limestone powder from Onich, as supplied to the Charlestown Lime Co. Ltd. in 1940. BGS Sample SL 35. British Geological Survey Petrology Collection sample number MC 7584. There are two main limestones in Invernessshire south-east of the Great Glen and of Dalradian Supergroup (Precambrian) age, the Balachullish Limestone and the Appin Limestone. The Appin Limestone crops out near Onich, on the north side of Loch Leven. It differs from the Balachullish Limestone in being dolomitic, but analyses of samples from the shore and from a disused quarry farther north show it to be of poor quality. It is doubtful therefore if the Invernessshire occurrences of the Appin Limestone are of economic value, although it should be noted that dolomites of fairly high quality occur in the same formation near Balachullish and Duror. |
