Abstract
The greater Eromanga Basin is an intracratonic Mesozoic basin covering an area of approximately 2,000,000 km2 in central and eastern Australia. The greater Eromanga Basin encompasses three correlated basins: the Eromanga Basin (central and western regions), Surat Basin (eastern region) and the Carpentaria Basin (northern region). The greater Eromanga Basin hosts Australia's largest known resources of groundwater as well as major onshore hydrocarbon resources, including significant coal bed methane (CBM) that has been discovered in recent years, and also contains extensive hot-sedimentary aquifer geothermal energy systems. Additionally, the basin has potential as a greenhouse gas sequestration site and will likely play a key role in securing Australia's energy future. Finally, although no major metallic mineral deposits are currently known in the greater Eromanga Basin, there is significant potential for undiscovered uranium mineralisation. A 3D geological map has been constructed for the greater Eromanga Basin using publicly available datasets. These are principally drilling datasets (i.e. water bores; mineral and petroleum exploration wells) and the 1:1,000,000 scale Surface Geology Map of Australia. Geophysical wireline logs, hydrochemistry, radiometrics, magnetic and gravity datasets were also integrated into the 3D geological map. This study has highlighted the potential of the southwest margin of the Eromanga Basin and the Euroka arch region to contain sandstone-hosted uranium mineral systems. The report demonstrates how incorporating disparate datasets in a 3D geological map can generate an integrated mapping solution with diverse applications: 1. Provide new insights into the geology and geodynamic evolution of the basin. 2. Identify hydrocarbon resource plays. 3. Assess the basin's mineral potential (e.g., sandstone-hosted uranium mineral systems). 4. Assess the basin's geothermal potential (e.g., hot-sedimentary aquifer geothermal systems). 5. Provide resource management information (e.g., groundwater). 6. Identify potential contaminants in groundwater.
