| Description: | A specimen of fluorspar, a calcium fluoride mineral belonging to the halides group of minerals. This specimen is from the Corrie Beg (Glengairn) Veins, Ballater, Aberdeenshire. British Geological Survey Petrology Collection sample number MC 7410. The Old Statistical Account of Scotland in 1794 states that pieces of lead ore had been found near the castle of Glengairn but no attempt had been made to find the vein. 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. Fluorspar is a mineral belonging to the cubic crystal system. It has a hardness of four on Moh's scale of hardness (semi-hard), it is a fragile mineral with perfect cleavage and vitreous lustre. |
