The digital '1:2 500 000 geological map of Western Australia' comprises four layers: the primary 1:2 500 000 State interpreted bedrock geology, the 1:2 500 000 State Cenozoic geology, the 1:2 500 000 State interpreted dyke suites, and the 1:2 500 000 State interpreted bedrock geology structural lines. The 1:2 500 000 interpreted geology contains geoscience data covering themes such as geology and tectonic boundaries that have been digitally rolled up from 1:500 000 data sources for optimal display at 1:2 500 000 scale. The Cenozoic geology layer can be superimposed over the bedrock layer to allow the extension of older bedrock geology under Cenozoic cover where geological and geophysical information permits, and to depict Cenozoic paleovalleys and additional significant Cenozoic cover. The dyke suites layer is primarily interpreted from aeromagnetic data, using mapped dyke extents as a guide. Individual dykes are assigned to named dyke suites wherever possible. The attribution of linear structures and dykes as concealed or exposed takes into account both the interpreted bedrock and the Cenozoic geology layers and does not reflect regolith cover. Detailed fault attribution has been simplified from the 1:500 000 scale, except in the case of major fault systems or tectonic boundaries. The nomenclature and hierarchy of lithostratigraphic units is based on the GSWA weekly updates from the Explanatory Notes System (ENS). In order to provide the most up-to-date geological information for the units in question, attribution from the original source is modified to remove superseded stratigraphic units, display correct stratigraphic relationships and include more recent geochronology. Stratigraphic units are mostly displayed at greater than or equal to Group or Suite level; Subgroups and Formations are only displayed where areal extent warrants it and the unit does not have a higher order parent.

The '1:10 000 000 large igneous provinces of Western Australia' is a companion layer to the '1:10 000 000 tectonic units of Western Australia'. Large igneous provinces (LIPs) are represented on this map as overlapping polygons that show the original interpreted extent of each province based on the preserved extents of the constituent magmatic units.

The digital '1:500 000 State interpreted bedrock geology of Western Australia' is an update to the '1:500 000 State interpreted bedrock geology of Western Australia, 2016'. It comprises three layers: the primary 1:500 000 State interpreted bedrock geology, the 1:500 000 State Cenozoic geology and the 1:500 000 State linear structures layer. The 1:500 000 State interpreted bedrock geology layer includes revised stratigraphy in the West Musgrave Province, West Arunta Orogen, East Pilbara, Capricorn Orogen, Eastern Capricorn basins and Murchison project areas; a new stratigraphic framework for the East Yilgarn project area is also included. The 1:500 000 State Cenozoic geology layer has no current updates from the 2016 revision. Compilation is based on published 1:100 000 and 1:250 000 Geological Series maps of Western Australia, together with GSWA and GA (AGSO, BMR) regional geological maps at scales from 1:250 000 to 1:1 000 000. Information from these maps has been modified locally, using geophysical datasets (magnetics, radiometrics and gravity), remote sensing imagery (ASTER and LANDSAT), seismic and magnetotelluric profiles, drilling, and unpublished geological mapping. The Cenozoic layer overlies the pre-Cenozoic layer to depict Cenozoic paleovalleys and other areas of significant Cenozoic bedrock. The linear structures layer refers primarily to pre-Cenozoic structures and attribution of concealed structures refers to those that are older than the pre-Cenozoic unit in question.
