Soils mapped in raster format with 90-m pixels. The soil classes are Western Australian Soil Groups. The soil type rasters were derived from the conventional soil landscape mapping (polygon maps) in 2013. The probability of occurrence of each soil class was predicted per pixel; the three most probable classes are available here, and individual class probabilities are available on request.

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sensing imagery (ASTER and LANDSAT), seismic and magnetotelluric profiles, drilling, and previously published and unpublished geological mapping.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up-to-date geological information for the units in question, attribution from the original source is modified to remove superseded stratigraphic units, display correct stratigraphic relationships, and include more recent geochronology.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 titanium-zircon mineral industry operates in the high-profile settledparts of the Swan Coastal Plain of SW Australia. Currently probably several billion dollars-worth of minerals are sterilized by urban, commercial and industrial developments in the region. Maps showing the distribution of the known deposits are an essential dataset needed by State and local Government agencies and authorities, and must be available widely to enable planning to avoid setting up the scenario where deposits are sterilized.

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.
