This boulder shows one set of stripes clearly being truncated by another set cutting across it. I'm still scratching my head trying to envisage how this happened! Pound coin for scale.
The Rosemarkie Inlier
An inlier is a geological term denoting an outcrop of older rocks which protrudes through younger rocks. North-east of Rosemarkie is a curious inlier made up of rocks which closely resemble the Moine and Lewisian rocks further west, being made up of the same sorts of ancient rocks which have undergone similar metamorphoses. In the Rosemarkie Inlier, however, these rocks are intruded and cut by numerous sheets and veins of salmon-pink leucogranite. The inlier is about 10 km long and 2 km wide, and is bounded on the west by Devonian sedimentary rocks. It lies parallel to the continuation of the Great Glen Fault, which is just offshore, and is thought to have been uplifted into its present position by movements related to the Fault.
