A recent drilling program in southeast South Australia has provided new insight into the late Cainozoic sequence of that area. Uplift of the region occurred during the Pleistocene, related in part to volcanic activity in the Mount Gambier-Mount Burr area. This, together with eustatic sea-level changes, resulted in the development of a regressive sequence, which over a period of 690 000 years or less, led to a 100 km seaward progradation of the shore-line between Naracoorte and Robe. The sequence is made up of a ridge-forming sandy facies comprising beach and very shallow marine sands at the base, and aeolian sands at the top. These sediments are separated by a fine-grained interdunal facies deposited initially under bay or estuarine conditions, grading into lagoonal and finally saline lacustrine conditions at the top. The sequence between Naracoorte and Robe holds great promise as a location for establishing Pleistocene sea-level changes. The current program suggests at least 20 major high sea-level stands during the past 690 000 years.
