| Description: | A specimen of fluorspar, also known as fluorite, from the Corrie Beg (Glengairn) Veins, Ballater, Aberdeenshire. British Geological Survey Petrology Collection sample number MC 7408. The main vein is associated with a fault that trends to the north-north-west and has several branches. The vein was worked for galena, a lead ore to a depth of thirty-six feet early in the 1800s. It yielded lead rich in silver. Heddle in his 'Mineralogy of Scotland' mentions the occurrence of two intersecting veins in gneiss containing galena and yellow zinc-blende associated with fluorspar and calcite. The host rock is intrusive hornblende schist and thin bands of siliceous schist of the Precambrian (Dalradian) Banffshire Series. |
