Extract

B. Pre–Cambrian, Rhyolitic Series.—(i) At the south–west end of the Craig–y–Dinas mass we find exposed a rock similar in every respect macroscopically to that which is found at Cil–y–Coed. Unfortunately it cannot be followed far, as the land is completely under drift, the top of Craig–y–Dinas itself being capped by a thick layer of drift.
