The Surat Basin is a sedimentary basin with approximately 2500 m of clastic fluvial, estuarine, coastal plain, and shallow marine sedimentary rocks, including sandstone, siltstone, mudstone, and coal. Deposition occurred over six cycles from the Early Jurassic to the Cretaceous, influenced by eustatic sea-level changes. Each cycle lasted 10 to 20 million years, ending around the mid-Cretaceous. Bounded by the Auburn Arch to the northeast and the New England Orogen to the southeast, it connects to the Clarence-Moreton Basin through the Kumbarilla Ridge. The Central Fold Belt forms its southern edge, while Cenozoic uplift caused erosion in the north. The basin's architecture is influenced by pre-existing faults and folds in the underlying Bowen Basin and the nature of the basement rocks from underlying orogenic complexes. Notable features include the north-trending Mimosa Syncline and Boomi Trough, overlying the deeper Taroom Trough of the Bowen Basin and extending southwards. The Surat Basin overlies older Permian to Triassic sedimentary basins like the Bowen and Gunnedah Basins, unconformably resting on various older basement rock terranes, such as the Lachlan Orogen, New England Orogen, and Thomson Orogen. Several Palaeozoic basement highs mark its boundaries, including the Eulo-Nebine Ridge in the west and the Kumbarilla Ridge in the east. Paleogene to Neogene sediments, like those from the Glendower Formation, cover parts of the Surat Basin. Remnant pediments and Cenozoic palaeovalleys incised into the basin have added complexity to its geological history and may influence aquifer connections. Overall, the Surat Basin's geological history is characterized by millions of years of sedimentation, tectonic activity, and erosion, contributing to its geological diversity and economic significance as a source of natural resources, including coal and natural gas.

This Bowen Basin dataset contains descriptive attribute information for the areas bounded by the relevant spatial groundwater feature in the associated Hydrogeology Index map. Descriptive topics are grouped into the following themes: Location and administration; Demographics; Physical geography; Surface water; Geology; Hydrogeology; Groundwater; Groundwater management and use; Environment; Land use and industry types; and Scientific stimulus. The Bowen Basin is part of the Sydney–Gunnedah–Bowen basin system and contains up to 10,000 m of continental and shallow marine sedimentary rocks, including substantial deposits of black coal. The basin's evolution has been influenced by tectonic processes initiated by the New England Orogen, commencing with a phase of mechanical extension, and later evolving to a back-arc setting associated with a convergent plate margin. Three main phases of basin development have been identified; 1) Early Permian: Characterized by mechanical extension, half-graben development, thick volcanic units and fluvio-lacustrine sediments and coal deposits. 2) Mid Permian: A thermal relaxation event led to the deposition of marine and fluvio-deltaic sediments, ending with a regional unconformity. 3) Late Permian and Triassic: Foreland loading created a foreland basin setting with various depositional environments and sediment types, including included fluvial, marginal marine, deltaic and marine sediments along with some coal deposits in the late Permian, and fluvial and lacustrine sediments in the Triassic. Late Permian peat swamps led to the formation of extensive coal seams dominating the Blackwater Group. In the Triassic, fluvial and lacustrine deposition associated with foreland loading formed the Rewan Formation, Clematis Sandstone Group, and Moolayember Formation. The basin is a significant coal-bearing region with over 100 hydrocarbon accumulations, of which about one third are producing fields. The Surat Basin overlies the southern Bowen Basin and contains varied sedimentary assemblages hosting regional-scale aquifer systems. Cenozoic cover to the Bowen Basin includes a variety of sedimentary and volcanic rock units. Palaeogene and Neogene sediments mainly form discontinuous units across the basin. Three of these units are associated with small eponymous Cenozoic basins (the Duaringa, Emerald and Biloela basins). Unnamed sedimentary cover includes Quaternary alluvium, colluvium, lacustrine and estuarine deposits; Palaeogene-Neogene alluvium, sand plains, and duricrusts. There are also various Cenozoic intraplate volcanics across the Bowen Basin, including central volcanic- and lava-field provinces.

This Clarence-Moreton Basin dataset contains descriptive attribute information for the areas bounded by the relevant spatial groundwater feature in the associated Hydrogeology Index map. Descriptive topics are grouped into the following themes: Location and administration; Demographics; Physical geography; Surface water; Geology; Hydrogeology; Groundwater; Groundwater management and use; Environment; Land use and industry types; and Scientific stimulus. The formation of the Clarence-Moreton Basin initiated during the Middle Triassic due to tectonic extension. This was followed by a prolonged period of thermal cooling and relaxation throughout the Late Triassic to the Cretaceous. Deposition of a non-marine sedimentary succession occurred during this time, with the Clarence-Moreton Basin now estimated to contain a sedimentary thickness of up to 4000 m. There were three main depositional centres within the basin, and these are known as the Cecil Plain Sub-basin, Laidley Sub-basin and Logan Sub-basin. The Clarence-Moreton Basin sediments were originally deposited in non-marine environments by predominantly northward flowing rivers in a relatively humid climate. The sedimentary sequences are dominated by a mixed assemblage of sandstone, siltstone, mudstone, conglomerate and coal. Changing environmental conditions due to various tectonic events resulted in deposition of interbedded sequences of fluvial, paludal (swamp) and lacustrine deposits. Within the Clarence-Moreton Basin, coal has been mined primarily from the Jurassic Walloon Coal Measures, including for the existing mines at Commodore and New Acland. However, coal deposits also occur in other units, such as the Grafton Formation, Orara Formation, Bundamba Group, Ipswich Coal Measures, and Nymboida Coal Measures. Overlying the Clarence-Moreton Basin in various locations are Paleogene and Neogene volcanic rocks, such as the Main Range Volcanics and Lamington Volcanics. The thickness of these volcanic rocks is typically several hundred metres, although the maximum thickness of the Main Range Volcanics is about 900 m. Quaternary sediments including alluvial, colluvial and coastal deposits also occur in places above the older rocks of the Clarence-Moreton Basin.

This Amadeus Basin dataset contains descriptive attribute information for the areas bounded by the relevant spatial groundwater feature in the associated Hydrogeology Index map. Descriptive topics are grouped into the following themes: Location and administration; Demographics; Physical geography; Surface water; Geology; Hydrogeology; Groundwater; Groundwater management and use; Environment; Land use and industry types; and Scientific stimulus. The Amadeus Basin is a sedimentary basin in central Australia that spans from the Neoproterozoic to Late Devonian, potentially Early Carboniferous, periods. It contains clastic, carbonate, and evaporitic sedimentary rocks, with a total thickness of 6,000 m to 14,000 m. The Neoproterozoic section alone is up to 3,000 m thick and is divided into four super-sequences separated by major unconformities. The basin is an active hydrocarbon province, with ongoing oil and gas production and the potential for further discoveries. Several key petroleum source rock units have been identified in the Amadeus Basin. The Gillen Formation, found in the northeast, consists of marine black shale, dolostone, sandstone, and evaporite, reaching a maximum thickness of 850 m. The Loves Creek Formation comprises deep water grainstone and mudstone overlain by stromatolite-bearing grainstone and dolostone, with a thickness of up to 500 m. The Johnnys Creek Formation is a unit composed of red bed and dolomitic limestone or dolostone, along with siltstone and sandstone, up to 400 m thick. The Inindia beds consist of sandstone, siltstone, chert, jasper, tillite, and dolostone, with a maximum thickness of 2,000 m and were deposited in shallow marine conditions. The Aralka Formation is a siltstone and shale unit with two members, the Ringwood Member and the Limbla Member, reaching a thickness of up to 1,000 m. The Pertatataka Formation is a turbiditic red and green siltstone and shale unit, along with minor feldspathic sandstone, deposited in a deep marine or marine shelf environment, typically about 350 m thick but up to 1,400 m thick at certain locations. The Winnall Group is a succession of sandstone and siltstone, with a maximum thickness of 2,134 m. The Chandler Formation is a poorly exposed unit consisting of halite, foetid carbonate mudstone, shale, and siltstone, deposited in a shallow marine environment, with halite deposits reaching thicknesses of 230 m to 450 m. The Giles Creek Dolostone is a carbonate and siltstone unit, with minor sandstone, deposited in a shallow-marine environment. The Horn Valley Siltstone is a thinly bedded shale and siltstone, with nodular limestone and sandy phosphatic and glauconitic interbeds, serving as the primary hydrocarbon source rock in the basin. Lastly, the Stairway Sandstone is 544 m thick and divided into three subunits, consisting of quartzitic sandstone, black shale, siltstone, mudstone, and phosphorites.

This Wiso Basin dataset contains descriptive attribute information for the areas bounded by the relevant spatial groundwater feature in the associated Hydrogeology Index map. Descriptive topics are grouped into the following themes: Location and administration; Demographics; Physical geography; Surface water; Geology; Hydrogeology; Groundwater; Groundwater management and use; Environment; Land use and industry types; and Scientific stimulus. The Wiso Basin, a large intra-cratonic basin in the central Northern Territory, covers about 140,000 square kilometres and is part of the Centralian Superbasin. It is bounded by the Tennant and Tanami regions to the east and west, while a thrust fault separates it from the Arunta Region to the south. The basin adjoins the Georgina Basin in the southeast and joins the Daly and Georgina basins beneath the Cretaceous strata of the Carpentaria Basin in the north. The basin contains a relatively flat, undeformed succession of strata that gently dip towards the main depo-centre, the Lander Trough. About 80% of the basin consists of shallow middle Cambrian strata, while the remaining portion is within the Lander Trough, containing a diverse succession of Cambrian, Ordovician, and Devonian units. The depositional history and stratigraphy reveal that early Cambrian saw widespread basaltic volcanism, with the Antrim Plateau Volcanics forming the base layer and aquitard of the Wiso Basin. The middle Cambrian deposits include the Montejinni Limestone, the oldest sedimentary unit, followed by the Hooker Creek Formation and the Lothari Hills Sandstone. The uppermost Cambrian unit is the Point Wakefield beds. The Ordovician deposits consist of the Hansen River beds, primarily composed of fossiliferous sandstone and siltstone deposited in shallow marine environments. The Devonian unit capping the basin is the Lake Surprise Sandstone, found in the Lander Trough area, formed in shallow marine, shoreline, and fluvial environments during the Alice Springs Orogeny. Three main hypotheses have been proposed for the formation of the Lander Trough: a large crustal downwarp before thrusting of Paleoproterozoic rocks, the formation of a half-graben by faulting along the southern boundary, or the formation of two en-echelon synclines by vertical block movement. While the majority of the Wiso Basin consists of shallow middle Cambrian rocks, the Lander Trough presents a more varied stratigraphic sequence, holding potential for Neoproterozoic and early Cambrian rocks. However, further drilling is needed to verify this. The presence of similar units in neighbouring basins provides valuable insight into the basin's geological history and development.

This Southern Australian Fractured Rock Province dataset contains descriptive attribute information for the areas bounded by the relevant spatial groundwater feature in the associated Hydrogeology Index map. Descriptive topics are grouped into the following themes: Location and administration; Demographics; Physical geography; Surface water; Geology; Hydrogeology; Groundwater; Groundwater management and use; Environment; Land use and industry types; and Scientific stimulus. Crustal elements are crustal-scale geological regions primarily based on composite geophysical domains, each of which shows a distinctive pattern of magnetic and gravity anomalies. These elements generally relate to the basement, rather than the sedimentary basins. The South Australian Element comprises the Archean-Mesoproterozoic Gawler Craton and Paleo-Mesoproterozoic Curnamona Province, formed over billions of years through sedimentation, volcanism, magmatism, and metamorphism. The region experienced multiple continental-continent collisions, leading to the formation and breakup of supercontinents like Nuna and Rodinia, along with periods of extensional tectonism. Around 1,400 Ma, both the Gawler Craton and Curnamona Province were cratonised, and during the building of the Rodinia supercontinent (1,300-700 Ma), the present configuration of the region emerged. The area between the Gawler and Curnamona provinces contains Neoproterozoic to Holocene cover, including the Adelaide Superbasin, with the Barossa Complex as its basement, believed to be part of the Kimban Orogen. The breakup of Rodinia in the Neoproterozoic (830-600 Ma) resulted in mafic volcanism and extensional episodes, leading to the formation of the Adelaide Superbasin, characterized by marine rift and sag basins flanking the Gawler Craton and Curnamona Province. During the Mesozoic and Cenozoic, some tectonic structures were rejuvenated, while sedimentary cover obscured much of the now flatter terrain. Metamorphic facies in the region vary, with the Gawler and Curnamona provinces reaching granulite facies, while the Adelaide Superbasin achieved the amphibolite facies. The Gawler Craton contains rocks dating back to approximately 3,150 Ma, while the Curnamona Province contains rocks from 1,720 to 1,550 Ma. These ancient regions have undergone various deformation and metamorphic events but have remained relatively stable since around 1,450 Ma. The Adelaide Superbasin is a large sedimentary system formed during the Neoproterozoic to Cambrian, with distinct provinces. It started as an intracontinental rift system resulting from the breakup of Rodinia and transitioned into a passive margin basin in the southeast and a failed rift in the north. Later uplift and re-instigated rifting led to the deposition of thick Cambrian sediments overlying the Neoproterozoic rocks. Overlying basins include late Palaeozoic to Cenozoic formations, such as the Eromanga Basin and Lake Eyre Basin, which are not part of the assessment region but are adjacent to it.

This Canning Basin dataset contains descriptive attribute information for the areas bounded by the relevant spatial groundwater feature in the associated Hydrogeology Index map. Descriptive topics are grouped into the following themes: Location and administration; Demographics; Physical geography; Surface water; Geology; Hydrogeology; Groundwater; Groundwater management and use; Environment; Land use and industry types; and Scientific stimulus. The Canning Basin, characterized by mostly Paleozoic sedimentary rocks with a maximum thickness of over 15,000 m, went through four major depositional phases from Early Ordovician to Early Cretaceous. The basin contains two main depocenters, the Fitzroy Trough-Gregory Sub-basin in the north and the Willara Sub-basin-Kidson Sub-basin in the south. The depositional history includes marine, evaporite, fluvial, deltaic, glacial, and non-marine environments. The basin's evolution began with extension and rapid subsidence in the Early Ordovician, followed by a sag stage with evaporite and playa conditions in the Late Ordovician and Silurian. The Devonian to Early Carboniferous phase involved marine, reef, fluvio-deltaic, and terrestrial sedimentation in the north and marginal marine to terrestrial systems in the south. The Late Carboniferous to mid-Triassic period saw non-marine and marine settings, including glacial environments. The basin then experienced mid-Jurassic to Early Cretaceous deposition, mainly in deltaic and non-marine environments. Throughout its history, the Canning Basin encountered multiple tectonic phases, including extension, compression, inversion, and wrench movements, leading to various depositional settings and sediment types. Around 250 petroleum wells have been drilled in the basin, with production mainly from Permo-Carboniferous sandstones and Devonian carbonates. Several proven and untested plays, such as draped bioherms, anticlinal closures, and fault blocks, provide potential for hydrocarbon exploration. Late Carboniferous and Jurassic mafic sills intersected in wells indicate additional geological complexity. Additionally, some areas of the Canning Basin are considered suitable for CO2 storage.

This Carnarvon Basin dataset contains descriptive attribute information for the areas bounded by the relevant spatial groundwater feature in the associated Hydrogeology Index map. Descriptive topics are grouped into the following themes: Location and administration; Demographics; Physical geography; Surface water; Geology; Hydrogeology; Groundwater; Groundwater management and use; Environment; Land use and industry types; and Scientific stimulus. The Carnarvon Basin is a large sedimentary basin covering the western and north-western coast of Western Australia, stretching over 1,000 km from Geraldton to Karratha. It is predominantly offshore, with over 80% of the basin located in water depths of up to 4,500 m. The basin is elongated north to south and connects to the Perth Basin in the south and the offshore Canning Basin in the north-east. It is underlain by Precambrian crystalline basement rocks. The Carnarvon Basin consists of two distinct parts. The southern portion comprises onshore sub-basins with mainly Paleozoic sedimentary rocks extending up to 300 km inland, while the northern section consists of offshore sub-basins containing Mesozoic, Cenozoic, and Paleozoic sequences. The geological evolution of the Southern Carnarvon Basin was shaped by multiple extensional episodes related to the breakup of Gondwana and reactivation of Archean and Proterozoic structures. The collision between Australia and Eurasia in the Mid-Miocene caused significant fault reactivation and inversion. The onshore region experienced arid conditions, leading to the formation of calcrete, followed by alluvial and eolian deposition and continued calcareous deposition offshore. The Northern Carnarvon Basin contains up to 15,000 m of sedimentary infill, primarily composed of siliciclastic deltaic to marine sediments from the Triassic to Early Cretaceous and shelf carbonates from the Mid-Cretaceous to Cenozoic. The basin is a significant hydrocarbon province, with most of the resources found within Upper Triassic, Jurassic, and Lower Cretaceous sandstone reservoirs. The basin's development occurred during four successive periods of extension and thermal subsidence, resulting in the formation of various sub-basins and structural highs. Overall, the Carnarvon Basin is a geologically complex region with a rich sedimentary history and significant hydrocarbon resources. Exploration drilling has been ongoing since 1953, with numerous wells drilled to unlock its hydrocarbon potential.
