Arckaringa Basin
Sedimentary basin in South Australia
From Wikipedia, the free encyclopedia
The Arckaringa Basin is an endorheic basin in Australia. It is 80,000 square kilometres (31,000 sq mi) in size and is located in South Australia.[1]
The basin surrounds the town of Coober Pedy in northern South Australia. It located in the north of the Gawler Block.[2]
Structure
The basin structure features an elevated central platform. There are both glacigene sediments deposited in the upper Carboniferous and Permian coal measures which are mostly covered by Mesozoic sediments.[2] The Boorthana Formation in the east bears diamictite.[3]
The eastern boundary of the basin contain some outcrops of pavements which prove glaciation.[3] Infills in the Arckaringa Basin are dominated by mass flow deposits.[4]
