Description: | Arkle, seen from the south-west across Loch Stack, Sutherland. Platform of Lewisian gneiss overlain unconformably by Cambrian quartzite; thrust planes within quartzite. The unconformity beneath the Cambrian rocks is planar, probably produced by marine erosion, which has removed all Torridonian strata from this part of the Moine Thrust belt. Screes are well developed on the lower, cross-bedded quartzite, but less so on the upper worm-burrowed 'pipe rock'. |
