| Abstract: | A textural analysis of the siliceous sediments component of a small saline lake in south-eastern South Australia (Lake Cantara
South) was undertaken. The data indicated periods of marine incursion, lagoonal dominance and elevated freshwater inputs.
Lake Cantara originated as a marine embayment; then followed periods of intermittent marine connection; finally, the lake
became athalassic (mostly saline but with occasional freshwater inundations). This history accords well with that derived
from an examination of mollusc fossils (marine, estuarine, athalassic saline, and freshwater forms) and with previously published
mineralogical, geochemical and geomorphological evidence. |
