| Caption: | Rock specimen of granite. Eilean Port a' Choit, 4.5 miles north-north-east of Scourie, Sutherland, Scotland. |
| Description: | The sample is a dark pink crystalline rock composed mainly of intergrown quartz and alkali feldspar, with small flakes of black biotite mica scattered throughout. British Geological Survey Petrology Collection sample number EMC163. Granite is one of the most well known and common rock types and it can vary markedly in colour and texture. Scotland is well known for its granite, ranging from the vivid red colours of Peterhead in the north-east, to the pale grey granites such as Criffel-Dalbeattie in the south-west. The zone of Laxford granite sheets separates the younger event of the Laxfordian Lewisian of mostly migmatites with pegmatites to the north and the much older less reworked Scourian granulites to the south. The rock is Lewisian (Precambrian) age. |
