Layered geology of Australia

Maintenance and Update Frequency: asNeeded | Statement: This is the third staged release of Geoscience Australia's national chronostratigraphic layered geology mapping program commenced under the EFTF, and builds on the first release for the Tennant Creek-Mount Isa area (Stewart, 2018) and the second release for the North Australian Craton (Stewart et al., 2020). This product includes updates to the North Australian Craton layered solid geology of Stewart et al (2020) including incorporation of the East Tennant layered solid geology of Clark et al. (2021), replacement of the Western Australian portion of the dataset with more recent source data from the Geological Survey of Western Australia (2020), and modification of polygons and stratigraphic information at boundaries between the North Australian Craton dataset and the adjoining states. | Purpose The Layered Geology of Australia is a national-scale compilation of seamless chronostratigraphic layered geology maps. These maps are compiled from a range of available surface and solid geology datasets at a variety of scales but optimised for use at a scale 1:1 000 000. Working with the state and territory governments, discrepancies in geological interpretation between state and territory geological survey datasets have been resolved. These new national maps enable a much improved understanding of the geological history and resource potential of Australia and will inform better decision making to support government, industry and community. | Geoscience Australia’s Exploring for the Future (EFTF) program provides precompetitive information to inform decision-making by government, community and industry on the sustainable development of Australia's mineral, energy and groundwater resources. By gathering, analysing and interpreting new and existing precompetitive geoscience data and knowledge, we are building a national picture of Australia’s geology and resource potential. This leads to a strong economy, resilient society and sustainable environment for the benefit of all Australians. This includes supporting Australia’s transition to net zero emissions, strong, sustainable resources and agriculture sectors, and economic opportunities and social benefits for Australia’s regional and remote communities. The Exploring for the Future program, which commenced in 2016, is an eight year, $225m investment by the Australian Government. The Layered Geology of Australia 1:1 000 000 scale dataset (2024 edition) is a seaml
