Leader: Dr Iain Allison
We will visit the former lead mine some 1 km west of and 150 m above Tyndrum Lower station and examine the mineralisation and the country rocks into which it was emplaced. The mineralisation consists of mainly vein quartz with sphalerite and galena. Other minerals which may be found are: chalcopyrite, pyrite, barite, and calcite. In the afternoon we shall make four stops along a generally level path in Glen Orchy where we shall see the Meall Garbh Psammite of the (lower) Grampian Group and the overlying Beinn Udlaidh Quartzite and Coire Daimh Pelite of the Appin Group.
