Abstract
This Northern 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. The Northern Australian Fractured Rock Province is a hydrogeological entity defined for this study, building upon earlier national-scale hydrogeological research. Australia's geological development was predominantly from west to east, with Archean rocks in the west, Proterozoic rocks in central Australia, and Phanerozoic rocks in the east. The North Australian Craton (NAC) is a significant tectonic element underlying 80% of the Northern Territory and extending to parts of Western Australia and northern Queensland, making up the core of the Northern Australian Fractured Rock Province. The NAC primarily consists of Paleoproterozoic rocks overlying Neoarchean basement. It is surrounded by Proterozoic terranes, including the Musgrave, Warumpi, and Paterson orogens to the south and south-west, the Terra Australis Orogen in the east, and the Western Australian Craton in the west. The Northern Australian Fractured Rock Province includes approximately twelve geological regions of mostly Proterozoic age, such as the Kimberley Basin, Speewah Basin, and Tanami Orogen, among others. Additionally, the province is partially overlain by the Kalkarindji Province, characterized by volcanic rocks. This widespread basaltic province serves as the basement for several significant sedimentary basins in northern Australia, including the Wiso, Ord, Bonaparte, Daly, and Georgina basins. In summary, the Northern Australian Fractured Rock Province is a hydrogeological region defined by combining various Proterozoic geological regions, mainly situated within the North Australian Craton. It is bounded by other Proterozoic terranes and covered in part by the Kalkarindji Province, which consists of volcanic rocks and forms the basement for several key sedimentary basins in northern Australia. Understanding this province is crucial for evaluating the hydrogeological characteristics and geological history of the region.

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.
