Abstract

A sequence of reversed graded beds occurs in a group of flaggy rocks intercalated within the Upper Dalradian grits of Inishowen. Usually these beds have a thickness between ½ inch and 2 inches, and are characterized by a laminated, argillaceous base which grades up into a fine-grained, arenaceous upper member.
