Extract

In their memoir on the Cauldron Subsidence of Glencoe, the authors, Messrs. Bailey, Clough, and Maufe, showed that the structure owes its origin to a cylinder that has sunk; around the edges there are various crush phenomena, culminating in fusion and actual lava. Alongside Glencoe is the granite mountain of Glen Etive, defined by a circular fault, and thus representing a cylinder that has been pushed up. The authors discuss the bearing of their work on general questions of geology; they show that the cylinder may simply sink, and the top be covered with the rocks originally in place upon it. Branca described a similar case in the Ries in Swabia. In others the circular fault has served as the orifice from which lava has been poured over the floor of the pit, as in the Hegau.
