Wiso Basin hydrogeological inventory

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.

Statement

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.
