Finally, it may be pointed out that the Loch Gruinart Fault isprobably the Great Glen Fault of the mainland, while the LochSkerrols Thrust is not unlikely the Moine Thrust of the North-West Highlands (see fig. 3, p. 138). 1 On the Progressive Metamorphism of some Dalradian Sediments in theReg-ion of Loch Awe Q.
