 Deposition of up to 10 km of marine and non-marine sedimentary rocks took place from the Neoproterozoic to the late Paleozoic.Paleozoic components of the basin are only found in South Australia.Along with other nearby sedimentary basins of similar age (Amadeus Basin, Georgina Basin), the Officer Basin is believed to have once been part of the hypothetical Centralian Superbasin which was fragmented during several episodes of tectonic activity.
