| Description: | Oblique aerial view of Quinag showing the Torridonian-Lewisian unconformity. Sutherland. Sail Ghorm in the foreground and Sail Gharbh behind. The large corrie in the distance is that of Loch a' Choire Dhuibh on Glas Bheinn. View looking south-east. Quinag is a relict mountain of Torridonian sandstone on an irregular basement of Lewisian gneiss. The sub-Torridonian surface was gently undulating but south of Quinag it became more irregular and locally had high relief. One hypothesis is that the gently undulating gneiss surface was part of a 'sub-alluvial bench' a planated piedmont surface formed below a retreating front of gneiss mountains which lay to the west of the Minch and from where most of the Torridonian sediments were derived. |
