| DESCRIPTION |
| Details (Known As) |
Marion Lake Geological Site, Dhilba Guuranda-Innes National Park [designated as a place of geological significance] |
| Registered Name |
Marion Lake Geological Site |
| Significance |
Marion Lake Geological Site is one of only a few places in South Australia where modern stromatolites can be found and may provide insight into the underlying processes required for the formation of these structures. The stromatolites at Marion Lake are estimated to be between 3000 to 5000 years old, and in appearance differ little from ancient examples which were formed by cyanobacteria, one of the earliest forms of life on earth. Too young to be fossils, the Marion Lake structures are a rare example of subfossil stromatolites and with the other geological features associated with the saline lake, creates a natural landscape that is of outstanding scientific importance due to its potential to yield detailed information about the natural history of South Australia.
STATEMENT OF GEOLOGICAL SIGNIFICANCE
Marion Lake Geological Site preserves rare modern stromatolites, uncommon geological formations, and fossilised evidence of past marine life. Rare and exceptional subfossil stromatolites found on the shores of the lake have a high likelihood to yield information about the natural development of the Yorke Peninsula coast. Remarkably fine laminations of aragonite and organic material preserve near-modern seasonal and climatic environmental changes.
The Lake's geological features demonstrate formation by the evaporation of water and deposition of minerals over thousands of years to form carbonate and gypsum deposits. Geological features such as boxwork limestone, springmounds, lunettes and tepees have all formed throughout the area and contribute to its geological significance. These, in tandem with similar structures at the nearby Deep and Inneston Lakes (SHP 16678) have the potential to yield detailed information on the natural evolution of South Australia.
Elements of heritage significance include (but are not necessarily limited to):
* Modern stromatolites,
* Geological features including but not limited to boxwork limestone, springmounds, lunettes and tepees,
* Remaining gypsum deposits as well as other mineral or evaporite deposits,
* Holocene-aged marine sands and seagrass,
* Calcreted, Pleistocene-aged dune,
* The environment of the lake and its surrounds.
Elements not considered to contribute to significance of place include (but are not necessarily limited to):
* Built structures including buildings, signage and trails.

Disclaimer
While due care has been taken to ensure that the SA Heritage Places Database accurately reflects the South Australian Heritage Register and listings of Local Heritage Places in Development Plans, the State of South Australia does not accept liability for the use of the SA Heritage Database for any purpose. Users should consult the Department for Environment and Water - Heritage South Australia to confirm the listing of State Heritage Places and the relevant Development Plan for Local Heritage Places/Contributory Items.
In the majority of cases, the maps of State Heritage Places on this web site show the footprints of the most significant structures on a registered Place. However, sometimes they simply indicate the complete area of land comprising the Place. Work is proceeding to further refine the mapping of such places. It is also important to note that development control is not limited to the registered structures but extends to their setting and structures nearby (what is termed ‘development affecting’ a State Heritage Place). Hence it is vital that exact details of the listed place and implications for any proposed development be discussed with Heritage South Australia staff, as they cannot be deduced solely from the information on this web site. The inclusion of a place in the SA Heritage Register gives no right of public access. Permission to visit properties must be sought from the owners. The accuracy of the mapping of State Heritage Places is not guaranteed. Please contact Heritage SA ( https://www.environment.sa.gov.au/topics/heritage/sa-heritage-register) if you believe there is an error.
