The data is a cropped portion of the generalised geology of Western Australia. The generalised geology contains geoscience data covering themes such as geology and tectonic boundaries. The data is held in GDA decimal degrees.

The map represents the Tasman Fold Belt System by a set of Stratotectonic Stages, the oldest, in Tasmania, being Mesoproterozoic and the youngest, in Queensland, Jurassic-Cretaceous. Each Stage is chiefly an assemblage of lithofacies elements that taken together, represent a major episode in the tectonic evolution of the System. The boundaries of Stages and elements are commonly unconformities or seperate significantly different facies. Most Stage boundaries are time-transgressive. Stratotectonic Stages and their age ranges are shown on the map by Stage numbers.

The 'Major crustal boundaries of Australia' map synthesizes more than 30 years of acquisition of deep seismic reflection data across Australia, where major crustal-scale breaks have been interpreted in the seismic reflection profiles, often inferred to be relict sutures between different crustal blocks. The widespread coverage of the seismic profiles now provides the opportunity to construct a map of major crustal boundaries across Australia. Starting with the locations of the crustal breaks identified in the seismic profiles, geological (e.g. outcrop mapping, drill hole, geochronology, isotope) and geophysical (e.g. gravity, aeromagnetic, magnetotelluric) data are used to map the crustal boundaries, in map view, away from the seismic profiles. For some of these boundaries, a high level of confidence can be placed on the location, whereas the location of other boundaries can only be considered to have medium or low confidence. In other areas, especially in regions covered by thick sedimentary successions, the locations of some crustal boundaries are essentially unconstrained. The 'Major crustal boundaries of Australia' map shows the locations of inferred ancient plate boundaries, and will provide constraints on the three dimensional architecture of Australia. It allows a better understanding of how the Australian continent was constructed from the Mesoarchean through to the Phanerozoic, and how this evolution and these boundaries have controlled metallogenesis. It is best viewed as a dynamic dataset, which will have to be further refined and updated as new information such as seismic reflection data becomes available.

The Geology of Australia data set documents the distribution and age of major stratigraphic, intrusive and medium to high-grade metamorphic rock units of onshore Australia. It is an ongoing compilation, subject to periodic revision as additional data becomes available. The data set was compiled to use at scales between 1:2,500,000 and 1:5,000,000 inclusive.
