Geoscience Australia’s OzChem for Western Australia and parts of South Australia and the Northern Territory.

OzChem is Geoscience Australia's national whole-rock geochemical database. Catchments shown in 'Hydrology – catchments DWER extended' were roughly used to determine extent included into South Australia and the Northern Territory. Each analysis includes a geographic location and a geological description, which includes the host stratigraphic unit, if known, and the lithology. Most samples have been collected by Geoscience Australia's field parties.
