Publicly available geology data are compiled to provide a common information base for resource development, environmental and regulatory decisions in the Galilee Basin region. This data guide gives examples of how these data can be used and supports the data package that provides the existing knowledge of the key geological intervals of the Galilee Basin and the overlying Eromanga, Lake Eyre and other Cenozoic basins.
The key geological intervals identified by the Trusted Environmental and Geological Information (TEGI) Program for resource assessment and groundwater system characterisation are termed play intervals and hydrostratigraphic intervals respectively. The Galilee Basin includes 5 plays, which are consolidated into 3 hydrostratigraphic intervals (see Table 1). Overlying the Galilee Basin are 9 play intervals of the Eromanga Basin, which are consolidated into 7 hydrostratigraphic intervals and 1 Cenozoic play interval and 1 hydrostratigraphic interval for the Lake Eyre and other Cenozoic basins. The geological groups and formations included in the plays and hydrostratigraphic intervals are summarised in the stratigraphic charts of Wainman et al. (2023a).
Gross depositional, depth structure and thickness maps are provided, with 3D model and cross-sections summarising the geology of the Galilee Basin and the overlying basins. The mapped depths and thicknesses of the key intervals are used to inform resource assessments and provide the framework for assigning groundwater data to hydrostratigraphic intervals.
