I have a few photos in this multimedia group Rock, Stone, Earth exhibition of rocks from the northern Flinders Ranges to the southern Fleurieu Peninsula in South Australia. The exhibition is curated by Janine Baker and Stephen Johnson, it is at the Onkaparinga Art Centre in Port Noarlunga, and it is being opened by Vic Waclawik on Sunday 26th September.

Featured artists are: Quentin Gore, Stephen Skillitzi, the late Władysław Dutkiewicz, John Richardson, Adam Dutkiewicz, Janette Humble, Deborah Odell, Gary Sauer-Thompson, Tina Moore, Stephen Johnson and Janine Baker.

My photos of  rocks include those large format ones made from the daily poodlewalks  in  the area between Petrel Cove and Kings Headon the southern Fleurieu Peninsula; secondly,  those from the Flinders Ranges made whilst I was on  camel treks in South Australia (one  to Mt Hopeless in 2018 and one from Blinman to Lake Frome in 2021); and thirdly, those made on walks in the Vulkathunha-Gammon Ranges National Park in 2021.

The rocks in the northern Flinders Ranges are very old — some dating back to before the lower Cambrian period with its explosion of life after the great glaciation of the planet. The Flinders Ranges contain an exceptional and unique geological heritage. This geological heritage with its Ediacaran fossils is the basis for the nomination of the Flinders Ranges for world heritage listing.

This heritage is based on a depositional system known as the Adelaide Rift Complex or Adelaide Superbasin, which includes the Fleurieu Peninsula and Kangaroo Island. The latter experienced a mountain building period around 500 million years ago that caused a substantial folding, buckling and faulting of the strata.

The rocks I photographed can be contextualized and linked by the geology of the Adelaide Superbasin in South Australia. The sedimentary rocks of the basin were deposited in a depression during the breakup of the supercontinent of Rodinia. The nature of the rocks suggest they were deposited in a mostly marine environment — a shallow sea — approximately 870 to 500 million years ago.
