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 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.

This dataset contains primary geological data, namely boundary types separating rock units. The linear features in this dataset are only comprised of geological boundaries and faults. The data have been collected by the Geological Survey of Victoria. The dataset is accompanied by another dataset representing structural lines.

Detailed geological mapping at 1:250 000 providing information on geological units, structural geology and faultlines, to produce a geological plan of the Rason region of Western Australia. The map was published in 1977.

Detailed geological mapping at 1:250 000 providing information on geological units, structural geology and faultlines, to produce a geological plan of the Nullagine region of Western Australia. The map was published in 2007. This data is held in GDA decimal degrees.

Detailed geological mapping at 1:250 000 providing information on geological units, structural geology and faultlines, to produce a geological plan of the Sahara region of Western Australia. The map was published in 1978. This data is held in GDA 94 decimal degrees.

Detailed geological mapping at 1:100 000 providing information on geological units, structural geology and faultlines, to produce a geological plan of the SANDSTONE region of Western Australia. The map was published in 2005. This data is held in GDA decimal degrees.

Detailed geological mapping at 1:250 000 providing information on geological units, structural geology and faultlines, to produce a geological plan of the Lennis region of Western Australia. The map was published in 1977. This data is held in GDA 94 decimal degrees.

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.

This dataset contains primary geological data, namely boundary types separating rock units. Other geological features (e.g. fault or dyke) are included where the feature forms a boundary to rock units. This layer has been superseded by the Seamless Geology layers for Faults - SG_SHEAR_DISPLACE_STRUC_250K Contacts - SG_GEOL_UNIT_CONTACT_250K The data have been collected by the Geological Survey of Victoria. The dataset is accompanied by other datasets representing structural lines, miscellaneous lines, miscellaneous polygons, metamorphism, and placer deposits.
