Gabbroic complex; it shows geochemically distinct, presently vertical gabbroic sheets which become progressively less basic as one travels north and finally the summit is made of granophyre. Believed to have been formed by cumulate crystalisation/fraction from an initially basaltic magma and rotated out of its initial horizontal layering by the Caledonian Orogeny.
