Sub-aerial Volcanicity in Snowdonia

Abstract

EXTENSIVE recent work in south-central Lleyn (F. J. F.), Beddgelert (N. R.) and the pass of Llanberis (F. J. F. and N. R.), supplemented by observations from the pass of Aberglaslyn (R. V. B.) warrants a new interpretation of Snowdonian volcanics of mid-Ordovician age.
