Continuation of the Great Glen Fault beyond the Moray Firth

Abstract

THE Great Glen Fault was shown by W. Q. Kennedy1 to be a sinistral tear fault on which a displacement of about 65 miles has occurred since Middle Old Red Sandstone time. E. M. Anderson1 considered that “the curvature of the fault trace may indicate that we are dealing with the south-western sector of a major fault and that the main extension of the dislocation will probably lie to the north-east”. This curvature is a gradual change of strike from about 040° in Loch Linnhe to about 035° at Inverness.
