Description: | Looking east towards Slioch from the A832, 2.8 km. east-south-east of Talladale, Ross & Cromarty. Torridonian sandstone of the upper part of the mountain rests with marked unconformity on the old gneiss land surface. In late Precambrian times (1000-750 Ma) the eroded land surface of the Lewisian gneiss was covered by a thick assemblage of terrestrial sedimentary rocks. They are commonly reddish or reddish-brown and laid down under fluviatile conditions with local accumulations of scree-breccia on or near the contacts with the Lewisian. It is thought that the Torridonian represents the last of several cycles of deposition and erosion since the Lewisian first became a land surface. The ancient landscape onto which the Torridonian was deposited was gently undulating however, locally, especially here at Slioch, the land surface had high relief with hills of gneiss rising up to 600 m. above the pre-Torridonian valley floors. |
