Description
Little Glenshee Little Glenshee lies 20 kilometres north-west of Perth, to the north of Little Glenshee farm on the edge of the Southern Highlands. This site displays downward-facing primary folds of the Loch Tay Nappe in the Birnam Slate Formation; this has a graded bedding unit (c. 50 cm) thick which indicates inversion. In the lower crags, there are well preserved folds of around 2 metres wavelength in siltstones and sandstones, having axes plunging gently North East and axial surfaces dipping steeply North West. The overall structural setting appears to be similar to the Dunkeld area. North West dipping, generally right-way-up, Birnam Slates appear in the North West limb of the primary downward-facing Aberfoyle "Anticline". In these, a downward-facing cleavage related to the Aberfoyle "Anticline" is developed. The importance of this site is that it has good, easily accessible, tectonic and sedimentary structures. The relationships deduced from the structures are vitally important in understanding the structure and stratigraphy of the Dalradian in the Highland Border region.
