This Maryborough-Nambour 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 Maryborough Basin is a half-graben intracratonic sag basin mainly filled with Early Cretaceous rocks, overlain by up to 100 m of Cenozoic sediments. It adjoins the older Nambour Basin to the south, comprising Triassic to Jurassic rocks. The boundary between the basins has shifted due to changes in sedimentary unit classifications, with the Cretaceous units now restricted to the Maryborough Basin and Jurassic and older units assigned to the Nambour Basin. Both basins are bounded to the west and unconformably overlies older Permian and Triassic rocks in the Gympie Province and Wandilla Province of the New England Orogen. In the south of the Nambour Basin, it partly overlaps with the Triassic Ipswich Basin. The Nambour Basin in the south is primarily composed of the Nambour Formation, with interbedded conglomerate, sandstone, siltstone, shale, and minor coal. Overlying this is the Landsborough Sandstone, a unit with continental, fluviatile sediments and a thickness of up to 450 m. In the north, the Duckinwilla Group contains the Myrtle Creek Sandstone and the Tiaro Coal Measures, which were formerly considered part of the Maryborough Basin but are now associated with the northern Nambour Basin. In contrast, the Maryborough Basin consists of three main Cretaceous units and an upper Cenozoic unit. The Grahams Creek Formation is the deepest, featuring terrestrial volcanic rocks, volcaniclastic sedimentary rocks, and minor pyroclastic rocks. The overlying Maryborough Formation was deposited in a continental environment with subsequent marine incursion and includes mudstone, siltstone, minor sandstone, limestone, conglomerate, and tuff. The upper Cretaceous unit is the Burrum Coal Measures, comprising interbedded sedimentary rocks deposited in fluvial to deltaic environments. The uppermost unit, the Eocene to Miocene Elliott Formation, includes sandstone, siltstone, conglomerate, and shale deposited in fluvial to deltaic environments. Cenozoic sediments overlying the Elliott Formation consist of Quaternary alluvium, coastal deposits, and sand islands like Fraser Island, influenced by eustatic sea level variations. Volcanic deposits and freshwater sediments also occur in some areas. Adjacent basins, such as the Clarence-Moreton Basin and Capricorn Basin, have stratigraphic correlations with the Maryborough Basin. The Oxley Basin lies to the south, overlying the Ipswich Basin. In summary, the Maryborough Basin and the older Nambour Basin exhibit distinct geological characteristics, with varying rock formations, ages, and sedimentary features, contributing to the diverse landscape of the region.

This McArthur 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 McArthur Basin, located in the north-east of the Northern Territory, is a Paleoproterozoic to Mesoproterozoic geological formation containing relatively undisturbed siliclastic and carbonate rocks, as well as minor volcanic and intrusive rocks. These sediments were primarily deposited in shallow marine environments, with some lacustrine and fluvial influences. The basin's thickness is estimated to be around 10,000 m to 12,000 m, potentially reaching 15,000 m in certain areas. It is known for hosting elements of at least two Proterozoic petroleum systems, making it a target for petroleum exploration, especially in the Beetaloo Sub-basin. Researchers have divided the McArthur Basin into five depositional packages based on similarities in age, lithofacies composition, stratigraphic position, and basin-fill geometry. These packages, listed from oldest to youngest, are the Wilton, Favenc, Glyde, Goyder, and Redback packages. The McArthur Basin is part of the broader Proterozoic basin system on the North Australian Craton, bounded by various inliers and extending under sedimentary cover in areas like the Arafura, Georgina, and Carpentaria basins. It is divided into northern and southern sections by the Urapunga Fault Zone, with significant structural features being the Walker Fault Zone in the north and the Batten Fault Zone in the south. The basin's southeastern extension connects with the Isa Superbasin in Queensland, forming the world's largest lead-zinc province. Overall, the McArthur Basin is an essential geological formation with potential petroleum resources, and its division into distinct packages helps in understanding its complex stratigraphy and geological history. Additionally, its connection with other basins contributes to a broader understanding of the region's geological evolution and resource potential.

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.
