Description: Cuillin Hills, looking up Loch Coruisk, Skye, Inverness-shire. Mountains composed of gabbro, cut by cone-sheets and dykes. Deep glacially-eroded basin. The Cuillin Hills are composed principally of layered gabbro, and minor ultrabasic rocks (mainly on Sgurr Dubh), formed by precipitation of crystals at the base of a magma chamber in the roots of a volcano. Several magma chambers were involved, whose products form intrusions which successively cut each other. The gabbros and ultrabasic rocks were intruded by a series of doleritic cone-sheets dipping towards Loch Coruisk, and by many subvertical dykes, mostly south-east-trending, but some radiating from the Cuillin centre.
