| Description: | A specimen of galena from the Wanlockhead Lead Mine, Glencrieff Shaft Stope in South Straitstep Vein, Wanlockhead, Dumfriesshire. British Geological Survey Petrology Collection sample number MC 7699. Almost all the veins in the district carry galena as the principal valuable mineral, a few carry copper ores in excess of other sulpides and have been worked for that metal. Most contain zinc blende (sphalerite) but not in commercial quantities. There is widespread alluvial gold in the area but no auriferous quartz veins have been found. The lead and zinc deposits are associated with lines of fracture and in many cases signs of repeated movement can be seen e.g. slickensided galena and blende. |
