Abstract
Australia's ancient river networks are substantially obscured by dunefields. The depths of incision of the river valleys into bedrock, the nature of sedimentary infill, and the palaeoenvironmental and geomorphic evolution of these fluvial systems are little known for much of the continent. The fluvial systems are defunct and the valleys are now typically disconnected chains of salt lakes with the relict valleys governed by groundwater processes. The palaeovalley sediments represent important aquifers in widespread parts of the Australian semi-arid to arid zone. They commonly contain the only available water resources to support mining activities, remote Aboriginal communities, the pastoral industry, and groundwater-dependent ecosystems (GDEs). In Western Australia, investigations are underway in two regions to assess palaeovalleys and their groundwater resources: the Paterson Province in the Great Sandy Desert, and the Murchison Province of the Archean Yilgarn Craton. A variety of technologies have been applied to provide a regional context for more detailed analysis.
