In general, a top down approach has been taken so that only the uppermost units for each era are shown.

Brief description

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 seamless national coverage of Australia’s surface and subsurface geology. Geology concealed under younger cover units are mapped by effectively removing the overlying stratigraphy (Liu et al., 2015). This dataset is a layered product and comprises five chronostratigraphic time slices: Cenozoic, Mesozoic, Paleozoic, Neoproterozoic, and Pre-Neoproterozoic. As an example, the Mesozoic time slice (or layer) shows Mesozoic age geology that would be present if all Cenozoic units were removed. The Pre-Neoproterozoic time slice shows what would be visible if all Neoproterozoic, Paleozoic, Mesozoic, and Cenozoic units were removed. In general, a top down approach has been taken so that only the uppermost units for each era are shown. However, in areas of relative geological complexity and where that detail was available in the source data, some units may show overlap. In these instances, the units are ordered from oldest (base) to youngest (top). The Cenozoic time slice layer for the national dataset was extracted from Raymond et al., 2012. Surface Geology of Australia, 1:1 000 000 scale, 2012 edition. Geoscience Australia, Canberra, and retains the data schema of that dataset. For that layer’s metadata, refer to https://dx.doi.org/10.26186/74855.

Geological units are represented as polygon and line geometries and are attributed with information regarding stratigraphic nomenclature and hierarchy, age, and lithology. All stratigraphic information populated in the dataset is derived from the Australian Stratigraphic Units Database. The dataset also contains a layer for structural features such as faults and shears.

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.

Notes

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.
