Structural Features of the Grey Granites of Aberdeenshire

Abstract

INTRODUCTIONThe area containing the quarries discussed in this paper extends inland from the City of Aberdeen for a distance of about twenty miles and is bounded on the north and south by the rivers Don and Dee. This is the area of the Newer Granites of Aberdeenshire, which C. B. Bisset has described in “A Contribution to the Study of Some Granites near Aberdeen” and has divided the acid igneous rocks into:—1. The Skene Complex: consisting of diorite, adamellite, grey granites, transition types and minor intrusions.2. Later Group: consisting of coarse red granites.
