Brief description

The geological data includes the spatial extents of the Kati Thanda - Lake Eyre Basin (KT-LEB) project area, geological basin and sub-basin boundaries, and geological models of the extent and thickness of the main Cenozoic sedimentary packages in the KT-LEB in central Australia. This data package has particular focus on the geological Lake Eyre Basin (LEB) and its main sedimentary depocentres of the Callabonna and Tirari sub-basins, and the Cooper Creek Palaeovalley. The new geological datasets available in this data package were developed as part of the project on the Cenozoic geology, hydrogeology, and groundwater systems of the Kati Thanda - Lake Eyre Basin, the results of which were published in Evans et al. (2024). This activity was undertaken as part of the National Groundwater Systems project in the Geoscience Australia Exploring for the Future program.

This geological data package contains the following eight datasets:

1. Spatial extents of the boundary of the KT–LEB project area.

2. Major sites of Cenozoic sediment deposition within the KT-LEB.

3. Total thickness of Cenozoic sediments in KT-LEB, with derived contours, hillshaded image and Cenozoic cover extent.

4. Saturated thickness model of Cenozoic sediments in the KT-LEB with derived contours, hillshaded image and Cenozoic cover extent.

5. Model of the base of Cenozoic surface of the KT-LEB project area, with derived contours, hill-shaded image and Cenozoic cover extent.

6. Model of thickness of Quaternary sediments of the KT-LEB with derived contours, hillshaded image and the Quaternary sediments extent outline.

7. Model of thickness of Namba Formation in KT-LEB, with derived contours, hillshaded image and the Namba Formation extent outline.

8. Model of thickness of Eyre Formation in KT-LEB with derived contours, hillshaded image and the Eyre Formation extent outline.

Statement:

The datasets within this data product are mostly derived through analysis and processing of pre-existing primary data sources. For example, the various datasets associated with groundwater bores and mineral exploration drill holes were obtained from existing sources of bore data, such as state and territory groundwater bore and mineral exploration datasets. For further details of the data sources, processing workflows and analytical methods used in this study, refer to the specific metadata documentation provided for each of the eight datasets within this data package.

Notes

Purpose
This data package provides access to the key geological datasets that were developed and used in the study of the Cenozoic geology, hydrogeology, and groundwater systems of the Kati Thanda – Lake Eyre Basin (Evans et al. 2024). These datasets were used to create many of the maps and associated images published within the Evans et al. (2024) Geoscience Australia Record. Most of the datasets are based on analysis and processing of existing stratigraphic data obtained from a variety of existing datasets, including groundwater bores, mineral exploration drill holes and petroleum exploration wells, as well as relevant data from existing surface geology mapping.
