| Abstract: | The Lewisian rocks in the area studied show a gradation from hornblende-felspar schists to striped and banded schists and gneisses to hornblendic and felsic lenses and pods. The structural elements together with the chemical, mineralogical and textural variations indicate that the different types of rocks were formed by metamorphic differentiation. The process of metamorphic differentiation included different forms of chemical and mechanical differentiation.In the area between Loch Shieldaig and Loch Bràigh Horrisdale, Gairloch, Ross-shire. |
