Geological lines (contacts, faults) and geological rock units, derived from 1:250,000 geology data. Rock units have been simplified based on a parent 1:500,000 unit, geological boundaries have been generalised to be suitable for 1:500,000 scale data. The digital data is available as a seamless state wide coverage and is used to produce the Geology of Tasmania 1:500,000 Scale map.

Geological lines (contacts, faults, linears), geological rock units, and structure data derived from 1:50,000 and 1:63,360 Digital Geological Atlas printed map series and 1:25,000 digital geology data where available. Geological units and boundaries have been generalised and compiled for 1:250,000 scale. The digital data is available as a seamless state wide coverage and is used to produce the Digital Geological Atlas 1:250,000 Scale map series.

The 2022 update of the digital '1:500 000 tectonic units of Western Australia' has been compiled using boundaries derived from the digital '1:500 000 State interpreted bedrock geology of Western Australia, 2020'. For the offshore component, the map uses data and divisions from the Geoscience Australia ‘Australian Geological Provinces’ GIS dataset, with polygons adjusted to match seamlessly into the onshore tectonic elements. The nomenclature and hierarchy for the tectonic units 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up-to-date geological information for the units in question, attribution from the original source is modified to remove superseded units, display correct tectonic relationships and include more recent geochronology. Significant changes to the tectonic framework of Western Australia in this version include: a) the obsolete Speewah Basin is now included in the Kimberley Basin; b) the obsolete Gunbarrel Basin is now part of the Canning Basin; c) the obsolete Northern and Southern Bonaparte Basins are combined into a single Bonaparte Basin, and the onshore extent of the Petrel Sub-basin has been modified to include the Weaber Group, and the offshore extent modified accordingly; d) the new Burringurrah Domain has been defined as part of the Gascoyne Province; e) the basaltic component of the Carson Volcanics is now represented as part of the Hart – Carson Large Igneous Province, rather than the Kimberley Basin into which it was extruded; f) significant re-interpretation of the granite–greenstone domains in the southwestern part of the Yilgarn Craton; g) the boundary between the Northern Perth Basin and Southern Carnarvon Basin has been modified along the western margin of the Northampton Inlier, and the offshore boundaries adjusted accordingly; h) the obsolete Pardoo Shelf has been assigned to the Lambert Shelf and extended onshore to the east of Port Hedland. The State is the highest level unit in the hierarchy and is subdivided at the next level into Archean to Paleoproterozoic cratons; Proterozoic orogens; Archean, Proterozoic and Phanerozoic basins (or superbasins); and igneous supersuites. All units depicted on this map, with the exception of basins and some igneous supersuites, are at the third or lesser hierarchical level. Cratons are subdivided into superterranes, terranes and domains. Orogens are divided into provinces and orogenic forelands, and may also incorporate sedimentary basins; provinces are further subdivided into terranes/zones.

The digital '1:10 000 000 tectonic units of Western Australia' has been compiled by rolling up and simplifying from the digital '1:500 000 tectonic units of Western Australia, 2015' for optimal display at 1:10 000 000 scale. For the offshore component, the map uses data and divisions from the Geoscience Australia ‘Australian Geological Provinces’ GIS dataset, with polygons adjusted to match seamlessly into the onshore tectonic elements. The nomenclature and hierarchy for the tectonic units are based on weekly updates from the GSWA Explanatory Notes System (ENS). In order to provide the most up-todate geological information for the units in question, attribution from the original source is modified to remove superseded units, display correct tectonic relationships and include more recent geochronology. This digital layer is designed to outline tectonic units at the highest levels within the tectonic hierarchy; that is, to delineate the areal extent of cratons, orogens, and basins.

Geological lines (contacts, faults, linears), geological polygons (rock units and alteration or metamorphism) and geological points (outcrops and structure data) derived from existing reports, 1:25,000 1:50,000 and 1:63,360 scale printed maps, new field mapping and interpretation of aerial photography, remote sensing data and airborne geophysical data. Digital data is available as a seamless layer, with the understanding that it may include unresolved edge-matching issues originating from mapping project boundaries in the source data. The digital data is used to produce the Digital Geological Atlas 1:25,000 Scale map series.

Detailed geological mapping at 1:100 000 providing information on geological units, structural geology and faultlines, to produce a geological plan of the Newman region of Western Australia. The map was published in 1989.

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.
