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up-todate geological information for the units in question, attribution from the original source is modified to remove superseded units, display correct tectonic relationships and include more recent geochronology.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.
