Caption: | Lead - copper vein from Blairlogie, Perthshire. |
Description: | Several old mines and trials for copper ore have been made on the veins of barytes which occur in the Old Red Sandstone volcanic rocks behind Blairlogie. British Geological Survey Petrology Collection sample number MC 7412. None of these old mines was of much value and they have long since been abandoned. The ores found were chalcocite and tetrahedrite with malachite and chrysocolla. The most westerly of the workings is a vein nine to twelve feet thick of pink barytes on the west side of the burn. Another vein that has undergone small-scale working for copper is 140 yards east of Blairlogie. A quarter of a mile further east two veins occur on the hillside, one carried barytes and disseminated copper ores. The most easterly has two feet of pink barytes and quartz and minute disseminated specks of copper ores. |
