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up-to-date geological information for the units in question, attribution from the original source is modified to remove superseded stratigraphic units, display correct stratigraphic relationships and include more recent geochronology.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 digital ‘1:100 000 State interpreted bedrock geology of Western Australia’ comprises three layers: the primary 1:100 000 State interpreted bedrock geology, the 1:100 000 State interpreted bedrock geology lines , and the 1:100 000 State linear structure layer. The product covers approximately 30% of Western Australia, with a focus on areas of exposed Archean and Proterozoic bedrock. The linear structure layer refers primarily to pre-Cenozoic bedrock structures. This compilation is based on Geological Survey of Western Australia’s (GSWA) published Geological Information Series (GIS) and Geological Exploration Packages (GEP) for which digital 1:100 000 and 1:250 000 interpreted bedrock geology is available. The data packages included are: Kimberley 2017, Tanami–Arunta 2016, West Musgrave 2017, East Albany–Fraser Orogen 2014 (1:250 000 pre-Mesozoic), West Capricorn 2016, East Yilgarn 2017, South Yilgarn 2016, Murchison 2017, and Pilbara 2014. Geological interpretation in these packages is based on extensive fieldwork and interpretation of geophysical datasets (magnetics, radiometrics and gravity), remote sensing imagery (ASTER and LANDSAT), seismic and magnetotelluric profiles, drilling, and previously published and unpublished geological mapping. With the exception of minor topological corrections, the spatial integrity of the source packages is maintained. For adjacent but separately compiled packages, seamless interpretation along the edges of project areas has not been executed in order to preserve the spatial integrity of the source information. The nomenclature and hierarchy for the lithostratigraphic units in the polygon and line layers are based on 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. The source package of each feature is captured as an additional attribute field. Individual packages are available via the Department of Mines, Industry Regulation and Safety’s (DMIRS) eBookshop.

The primary 1:2 500 000 State interpreted bedrock geology (DMIRS-014) is one of four digital data layers that make up the 1:2 500 000 geological map of Western Australia. The other three are 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 (DMIRS-013). 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 interpreted 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 nomenclature and hierarchy of lithostratigraphic units is based on the GSWA Explanatory Notes System (extracted September 2015). 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 data are held in GDA94 decimal degrees. This dataset was formally known as 1:2 500 000 State interpreted bedrock geology (DMP-011)

This dataset is a 1:50 000 geological map sheet index for available geological maps produced by the Geological Survey of Western Australia (GSWA).

This dataset is a 1:1 000 000 geological map sheet index for available surface geological maps produced by the Geological Survey of Western Australia (GSWA).

The 1:500 000 State interpreted bedrock geology (DMIRS-016) is one of three digital data layers that make up the 1:500 000 geological map of Western Australia. The other two are the 1:500 000 State Cenozoic geology and the 1:500 000 State linear structures layer (DMIRS-015). 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 nomenclature and hierarchy for the lithostratigraphic units are based on the GSWA Explanatory Notes System (extracted April 2016). Data are held in GDA94 decimal degrees.

"The ‘1:2 500 000 major crustal boundaries of Western Australia, 2021’ digital layer is a regional compilation of interpreted crustal boundaries that penetrate the lithosphere or bound tectonic units at the terrane or province scale. These boundaries have been interpreted and extrapolated from a variety of geological and geophysical datasets, primarily seismic reflection profiles, outcrop geology, and potential field data (gravity and aeromagnetics). Tectonic events ascribed to each boundary are defined in the GSWA Explanatory Notes Database (February 2021). The positional accuracy of these boundaries is low, due primarily to their crustal scale and uncertainties in interpreting the primary data sources, and consequently this map is best used at the nominal scale or smaller.
