| DESCRIPTION |
| Details (Known As) |
Red Cliff Point, Winninowie Conservation Park [including adjacent seabed, sand and seagrass banks] [Designated as a place of geological significance] |
| Registered Name |
Red Cliff Point Geological Site |
| Significance |
The coastal section of Red Cliff Point Geological Site demonstrates a succession of uncommon arid-temperate depositional environments and changing sea levels throughout the past 7-1.6 thousand years. The location provides a sheltered environment allowing for sediments to be almost entirely tidally dominated so that sea levels, kept in place mostly through clumped sands and seagrass in bioherms, are exceptionally well preserved and can be traced over thousands of years. As a result, Red Cliff Point Geological Site contains some of the best and rarest examples of Holocene, non-tropical bioherms in the world. Red Cliff Point Geological Site is a single, high-quality locality that affords an excellent opportunity to research preserved depositional environments and sea levels which continue to develop in the modern day.
STATEMENT OF DESIGNATION
Designated Place of Geological Significance
Red Cliff Point Geological Site preserves sedimentary layers of Holocene-aged seagrasses that demonstrate previous sea levels over the last 7-1.6 thousand years. The sheltered, arid-temperate environment preserved within the sediment at Red Cliff Point Geological Site provides insight into previous depositional environments across supratidal, intertidal and subtidal zones. These varied tidal ranges have allowed for the continued study of biological and geological processes as they develop. There are no comparable coastal localities that display a similar range in South Australia making it highly significant for reconstructing the coastal evolution of the State.
