Publicly available geology data are compiled to provide a common information base for resource development and regulatory decisions in the Galilee Basin region. This data guide gives examples of how the compiled data can be used. It supports a data package that presents core photographs, existing knowledge of the stratigraphy, and structural elements for the Galilee Basin and the overlying Eromanga, Lake Eyre and other Cenozoic basins.
Stratigraphic frameworks capture the geological groups and formations that make up the sedimentary sequence in the Galilee Basin region. The Galilee Basin includes 4 stratigraphic groups. From deepest to shallowest, these are the Joe Joe Group, Betts Creek group, Rewan Group and Clematis Group. Overlying the Galilee Basin are the geological formations of the Eromanga, Lake Eyre and other Cenozoic basins.
The frameworks include the stratigraphic intervals used by the Trusted Environmental and Geological Information (TEGI) Program. From the base of the Galilee Basin to the top of overlying Cenozoic basins, the sedimentary sequence is categorised into 15 play intervals for resource assessment mapping and 11 hydrostratigraphic intervals for characterising groundwater systems (Wainman et al., 2023).
Structural elements maps summarise where the sedimentary sequence has been deposited and later deformed by crustal movements. Structure information is used in assessing the geological potential for resources and interpreting groundwater flow and connectivity at the basin scale. The stratigraphic frameworks and structural elements provide the basic geological context for the Galilee Basin region geological, resource and environmental assessments.
