Abstract
This South Nicholson 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. This South Nicholson 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 South Nicholson Basin is a Mesoproterozoic sedimentary basin spanning Queensland and the Northern Territory and is bordered by neighbouring provinces and basins. The basin unconformably overlies the Lawn Hill Platform of the Mount Isa Province to the east, is bound by the Warramunga and Davenport provinces to the south-west, the Murphy Province to the north and the McArthur Basin to the north-west. It extends southwards under younger cover sequences. Rock units in the basin are correlated with the Roper Group in the McArthur Basin, forming the 'Roper Superbasin.' The underlying Mount Isa Province contains potential shale gas resources. The basin mainly consists of sandstone- and siltstone-bearing units, including the South Nicholson Group, with a prevailing east to east-northeast structural grain. Mild deformation includes shallowly plunging fold axes and numerous faults along a north-west to south-east shortening direction. Major geological events affecting the South Nicholson Basin region include the formation of the Murphy Province's metamorphic and igneous rocks around 1850 million years ago (Ma). The Mount Isa Province experienced deposition in the Leichhardt Superbasin (1800 to 1750 Ma) and Calvert Superbasin (1725 to 1690 Ma). The Isa Superbasin, with extensional growth faulting in the Carrara Sub-basin (~1640 Ma), deposited sediments from approximately 1670 to 1590 Ma. Subsequently, the South Nicholson Group was deposited around 1500 to 1430 Ma, followed by the Georgina Basin's sedimentation. The basin shows potential for sandstone-type uranium, base metals, iron ore, and petroleum resources, while unconventional shale and tight gas resources remain largely unexplored. The Constance Sandstone holds promise as a petroleum reservoir, and the Mullera Formation and Crow Formation serve as potential seals.

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.
