Ord Basin hydrogeological inventory
This Ord 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 Ord Basin, an intracratonic sedimentary basin, covers about 8000 square kilometres on the border of Western Australia and the Northern Territory. It was once part of the extensive Centralian Superbasin, which deposited sediments across central and northern Australia from the Proterozoic to early Palaeozoic era. The Ord Basin comprises three synclines with up to 2500 m of Cambrian and Devonian sedimentary rocks, separated by major faults and Proterozoic basement highs.
The basin's northern boundary is defined by the Halls Rewards Fault and Proterozoic basement rocks, separating it from the Bonaparte Basin. The western edge overlies rocks of the Paleoproterozoic Halls Creek Orogen, while the eastern margin is separated from the Wiso Basin by volcanic Kalkarindji Province and Proterozoic Birrindudu and Victoria basins. The southern boundary is formed by the Negri Fault and Proterozoic basement highs.
The depositional history of the Ord Basin can be divided into three phases. The early Cambrian witnessed extensive basaltic volcanism, forming the Antrim Plateau Volcanics. Subsequently, the Cambrian marine transgression deposited carbonates and clastic rocks of the Goose Hole Group, including the Elder and Negri Subgroups. The Late Devonian saw the deposition of continental sandstones and conglomerates of the Mahony Group.
Throughout the basin's evolution, tectonic movements and erosional processes shaped its present configuration. The Alice Springs Orogeny (450 to 300 Ma) caused deformation and landscape changes, resulting in the deposition of the Mahony Group. Periodic reactivation of growth faults in the underlying Birrindudu Basin and subsequent erosion contributed to the basin's current structure.
The Ord Basin's three synclines are the Hardman Syncline (southern and largest), the Rosewood Syncline (central), and the Argyle Syncline (northern). The Hardman Syncline holds the full succession of basin strata.

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.
