Some differential weathering of tors on Bodmin Moor has been found to be due to narrow zones of greisen. These zones are not related to the joint system in the granite and appear to have arisen by the alteration of feldspars in the path of escaping late-magmatic fluids.

The Skiddaw Group between Buttermere and Troutbeck is approximately 6,000 feet thick and can be subdivided into four formations which in ascending order are: Hope Beck Slates; Loweswater Flags; Mosser-Kirk Stile Slates; Latterbarrow Sandstone. The coarser elastics exhibit most of the characteristics of sediments deposited by turbidity currents. The source of these deposits is thought to lie to the south. The occurrence of contemporaneous vulcanism in the Loweswater Flags on Watch Hill has been confirmed. Tourmaline and andalusite are recorded for the first time from the metamorphic aureole east of Crummock Water.
