Architecture of the Arrowie Basin, South Australia, Based on Deep Seismic Reflection Data

The Arrowie Basin in South Australia represents the last phase of sedimentation in the Neoproterozoic to Cambrian Adelaide Rift System. As part of the Onshore Energy Security Program funded by the Australian Government, Geoscience Australia, in conjunction with PIRSA, acquired a ~60 km long deep seismic line (08GA-A1) in 2008 across the Arrowie Basin, immediately to the west of the central Flinders Ranges. The basin is of interest for petroleum exploration, because about 15 km to the south of the seismic line, the Wilkatana wells, drilled in the 1950s, encountered non-commercial bituminous hydrocarbons in the Cambrian succession. In 2009, Torrens Energy acquired a ~40 km long seismic line (09TE-01) at Parachilna, about 90 km to the north of the GA line as part of their geothermal exploration program. In the vicinity of these seismic lines, the Arrowie Basin forms part of the essentially undeformed Stuart Shelf (in the west) and the Torrens Hinge Zone (a zone of faulting and folding in the east). The Torrens Hinge Zone occurs immediately to the west of the highly folded component of the Adelaide Rift System in the Flinders Ranges.
