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sensing imagery (ASTER and LANDSAT), seismic and magnetotelluric profiles, drilling, and previously published and unpublished geological mapping.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up-to-date geological information for the units in question, attribution from the original source is modified to remove superseded stratigraphic units, display correct stratigraphic relationships, and include more recent geochronology.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 digital '1:500 000 tectonic units of Western Australia, 2017' has been compiled using boundaries derived from the digital '1:500 000 State interpreted bedrock geology of Western Australia, 2016' following the principles first used on the '1:500 000 Tectonic units of Western Australia — Preliminary Version' (2007). 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 the GSWA Explanatory Notes System. 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 reworking of basins and craton margins into orogens and orogenic forelands is represented on a companion layer, the '1:500 000 orogenic events of onshore Western Australia, 2015'. Igneous supersuites are further divided into suites, and both may be constituents of cratons, orogens, or large igneous provinces (LIPs). Basins are divided into sub-basins and sub-basin elements, which include shelves, highs, terraces, arches, platforms, ridges, troughs, embayments and grabens, and are locally ranked and stacked according to age where units overlie each other. The order of overlapping polygon units is indicated by the DRAWORDER field; the draw order may display incorrectly in the MapInfo format type. Any tectonic unit within the hierarchy may also be preserved as an inlier or outlier, in which case it is depicted as a separate unit. Polygons on this map represent the present-day area of tectonic units, without inference on their original extent.

The WACHEM database is a compilation of multi-element geochemistry of rocks unconsolidated surface material (regolith) and drill core collected by the Geological Survey of Western Australia. Samples have been analysed for a range of major element oxides, trace elements, rare earth elements (REE), and isotopes by a variety of analytical approaches at commercial, government and university laboratories. In most cases, analysis of unknowns has been carried out along with samples of know composition (reference materials), a second sample of the unknown (sample duplicate), and material which does not contain detectable amounts of elements of interest (blank). These data are included with analysis of unknowns, and these quality control data can be used to gauge the quality of analysis. For inclusion in the geochemical database, analytical data for each element in each sample must include the unit of measurement, lower level of detection (LLD) of that element, and an indication of the analytical technique (usually specified as a laboratory-specific code). To minimise the inclusion of spurious data in the database, analytical batch data are loaded with reference to a set of look up tables, against which data can be checked for consistency.
