Details (Known As) Stromatolites in the Precambrian Trezona Formation, Ikara-Flinders Ranges National Park
Registered Name Stromatolites in the Precambrian Trezona Formation
Significance Superb examples of stromatolites are exposed on faces of limestone of the Trezona Formation in the banks of the Enorama Creek. These exposures are considered to be of outstanding merit. The stromatolites are all domed, but exhibit a variety of shapes in detail, ranging from broad algal mats through individual mushroom-shaped growths to a series of parallel columns. Stromatolites are layered sedimentary structures left behind by the life activities of various primitive micro-organisms and are the earliest evidence we have of the existence of life on earth. It was also in this area that Sir Douglas Mawson (1949) recognised evidence of a Precambrian glaciation in the overlying tillite of the Elatina Formation and correlated it with glacial sequences in sedimentary rocks south of Adelaide.

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.
