| Description: | Map of the Highland Border slate belt. The belt runs roughly parallel and north-west of the Highland Boundary Fault and at a distance of from 1 to 4 miles from it. It is an almost continuous belt of slate-rock which can be traced from the North Sea to the Firth of Clyde. The slates near the Highland Border have been given a variety of names from the different localities where they have been worked, e.g. Dunoon Phyllites, Luss Slates, Aberfoyle Slates, Dunkeld Slates. The geologist, however, prefers to apply a general name to rocks belonging to the same formation wherever they occur. The general name chosen in this case is the Aberfoyle Slate, part of the Southern Highland Group of the Dalradian (Precambrian). In colour the Aberfoyle Slates include blue, grey, green and purple varieties. They are lighter in colour than the dark grey slates of Ballachulish and the Western Highlands (Easdale, etc.). They also have complete absence of pyrites crystals (`diamonds?) unlike the Ballachulish and Easdale Slates. As a broad generalisation it may be stated that the slates from the Highland Border region are slightly thicker and with slightly less regular surfaces than those from Ballachulish and the West Highlands, though it does not necessarily follow that the slates from a particular quarry along the Highland Border are invariably heavier than those from a particular quarry in the other areas. |
