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up-to-date geological information for the units in question, attribution from the original source is modified to remove superseded units, display correct tectonic relationships and include more recent geochronology.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. {"type": "Polygon", "coordinates": [[[106.56906097500007, -37.61054613799996], [129.00001022800006, -37.61054613799996], [129.00001022800006, -9.381389997999975], [106.56906097500007, -9.381389997999975], [106.56906097500007, -37.61054613799996]]]} 106.56906097500007 129.00001022800006 -37.61054613799996 -9.381389997999975 500 000 Geology Geosciences Tectonics Tectonics units 1:500 000 (DMIRS-037) documentDigital 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. GDB SHP TAB KMZ ArcGIS Server Map Service documentDigital An ArcGIS Server Map Service offers access to a geographic dataset - such as a map or imagery - by providing a set of tiled images for use in web-based maps. Depending on the capabilities enabled, this web service may also allow a client to dynamically draw, search, and query its features. This service is aimed at advanced geographical information users, and will require access to geographical information system (GIS) software such as ArcGIS and QGIS. API ArcGIS Server Map Service Web Mapping Service documentDigital Web Map Service (WMS) is a standard protocol for serving georeferenced map images over the internet that are generated by a map server using data from a GIS database. WMS allows a user to spatially visualise the dataset, and query individual features, but does not allow downloading the raw data. This service is aimed at advanced geographical information users, and will require access to geographical information system (GIS) software such as QGIS and ArcGIS. WMS
