A Late Palaeozoic glaciated granite surface at Port Elliot, South Australia

Abstract

A glaciated granite pavement, discovered at Port Elliot, South Australia, shows features that indicate an east to west movement of Late Palaeozoic ice, and thus significantly extends the known area of approximate east to west ice movement on Fleurieu Peninsula. The granite pavement and the profusion of granite erratics, together with the probable existence of an originally extensive pluton of Encounter Bay Granites, suggest the possible dissection of the pluton during the glaciation to form the present outcrop distribution.
