| Description: | A specimen of galena from Clachan Beag, Loch Fyne. Galena is lead sulphide, a mineral belonging to the cubic crystal system. British Geological Survey Petrology Collection sample number MC 7345. Galena is very heavy and fragile with perfect cleavage. The old mine at Clachan Beag mentioned in the Old Statistical Account is situated on the hillside one quarter of a mile south-west of Clachan Beag and about 200 yards from the sea. The deposit is a metasomatic replacement of part of a bed of limestone. The replacement has given rise to a highly complex ore containing galena, blende and pyrites in a siderite matrix. |
