The Merinjina Tillite was formed by glacier transportation of silts, sands, rocks and boulders which came to settle on the sea floor as the glacier melted, 643 -750 million years ago.
Volcanics are not a common sight in the Flinders Ranges but an example of Wooltana Volcanics is visible on the Paralana Hot Springs Road at Arkaroola. The role of volcanic activity in the formation of the Flinders Ranges is outlined in the essay Legacy of Time by the Royal Geographical Society of South Australia.
Limestones and Dolomites of the Balcanoona formation were fractured by fault activity and infilled with silica rich waters, cementing into this silicified breccia on the Paralana Hot Springs road.
The stunning Ochre Wall on the road to Paralana Hot Springs is the comprised of weathered laminated silts and shales of the Angepena Formation.
