Caption: Muscovite mica from Loch Affric area.
Description: In Scotland mica pegmatites occur in the Highland Region, usually as small disconnected and lenticular bodies. Most are found in the Precambrian Moine series in two areas of the Northern Highlands. A western belt extends from Knoydart southwards to Loch Shiel and Loch Sunnart and there is an eastern belt in the Strathpeffer and Garve districts. British Geological Survey Petrology Collection sample number MC 7384. Mica is a collective name for various aluminium silicate minerals that are characterized by perfect basal cleavage. Of the many micas, muscovite has major industrial importance. The uses of mica are based on a unique combination of physical, chemical and electrical properties. Sheet mica is used mainly by the electrical and electronic industries.
