| Caption: | Rock specimen of sandstone from Clashach Quarry, Hopeman, Moray, Scotland. |
| Description: | Fine to medium-grained, quartz-rich sandstone with no obvious bedding and a uniform texture. British Geological Survey Petrology Collection sample number EMC5867. The sample has a strong pale orange-yellow colour caused by the presence of very fine-grained iron oxide coatings around the individual sand grains. More obvious darker speckled grains are caused by the presence of larger individual grains of iron oxide. Clashach Quarry was operating in the latter part of the 19th century as one of a number of quarries on the coastline of the Moray Firth near Elgin, exploiting the Permian and Triassic sandstones that outcrop in the Hopeman area. Transport was initially by sea, and later the quarries were connected by railway. Clashach is one of the few sandstone quarries operating in Scotland today, and is much favoured for the decorative nature of the stone which has been used for prestigious new-build projects such as the National Museums of Scotland in Edinburgh in 1998. Clashach stone is also favoured for restoration work, and has been used as a replacement for Craigleith stone in Edinburgh, because of its fine-grained, quartz-rich nature. Size of specimen: 13x8x7 cm. Munsell colour code and colour 10YR7/6, yellowish orange. |
