III.—The Origin and Mode of Formation of the Permian Breccias of the South Devon Coast

Abstract

After visiting in 1905 the excellent exposure of the Permo-Carboniferous Dwyka Conglomerate, containing glacially striated boulders, overlying glacially striated Barberton beds at the foot of Gotshe Mountain in the Vryheid district of Natal, it occurred to me to examine the Permian breccias of the South Devon coast to see whether I could find any evidence of their being of glacial origin.
