| Description: | Suilven, looking north-east from 1.6 km. south of Rhegreanoch, Ross & Cromarty. Torridonian sandstone forming isolated 'inselberg' on a platform of Lewisian gneiss. The foreground shows a typical outcrop of the Lewisian forming the classic 'knock and lochan' type topography. It is characterized by irregular ice-scoured bedrock lumps and small hills with many intervening irregular rock-basin lakes with poorly integrated drainage. The Lewisian Complex is a residual fragment of the ancient Laurentian continental mass. The gneisses represent a long and varied part of the earth's history. They show evidence of having been formed and repeatedly deformed, often deep in the earth's crust over a period of nearly 1800 Ma up until c. 1100 Ma when they were uplifted, probably to near their present level when they formed the basement on which the Torridonian (and farther to the east Moine) assemblages were deposited. |
