Abstract
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.

Lineage
This document for the National Hydrogeological Inventory was created through the compilation and analysis of various national geospatial datasets and a range of supporting scientific and technical literature. In most cases, the spatial boundary (polygon) for the region was sourced from the Geoscience Australia Geological Provinces 2018 dataset. The geospatial data reported for the region of interest were selected by spatial queries of the region's polygon using Geographic Information System (GIS) applications. A variety of national-scale datasets were assessed for each region, with these data relevant to the study of groundwater, hydrogeology and related social, cultural or environmental characteristics. These data are published by various organisations (mostly Australian Government entities) and include fundamental Australian datasets such as the National Groundwater Information System (NGIS), National Aquifer Framework, Atlas of Groundwater Dependent Ecosystems and the Collaborative Australian Protected Areas Database (CAPAD). A complete list of all data used to develop the National Hydrogeological Inventory, and the various data processing and analysis methods used, will be released as part of a future Geoscience Australia publication focused on the hydrogeological inventory methodology. The document also contains written summary information about the geology, hydrogeology and related features of the region of interest. These narrative summaries were compiled by Geoscience Australia researchers based on literature review and analysis of a range of scientific and technical publications about the region. The reports use similar document templates to ensure the consistency of information provided across the entire Australian continent.
