I.—On some Inclusions in the Great Whin Sill of Northumberland

Abstract

The inclusions to be described in this paper occur in the Whin Sill at Snook Point on the coast of Northumberland. This is the most northerly exposure of the whin in the coast-section which stretches from Cullernose Point, through Dunstanburgh, to Beadnell Sands; and it is here that the outcrop leaves the coast and sweeps out to sea, to reappear further north in the Fame Islands and, on the mainland, at Bamburgh.
