The Layered Geology of Australia web map service 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. 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.

The Cenozoic alkaline and related igneous rocks of Australia web map service depicts the spatial representation of the alkaline and related rocks of Cenozoic age.

The Solid Geology of the North Australian Craton web service delivers a seamless chronostratigraphic solid geology dataset of the North Australian Craton that covers north of Western Australia, Northern Territory and north-west Queensland. The data maps stratigraphic units concealed under cover by effectively removing the overlying cover (Liu et al., 2015). This dataset comprises five chronostratigraphic time slices, namely: Cenozoic, Mesozoic, Paleozoic, Neoproterozoic, and Pre-Neoproterozoic.

<div>Groundwater systems hosted within Cenozoic rocks and sediments are vitally important for supporting communities, industries and the environment throughout central Australia's Kati Thanda – Lake Eyre Basin (KT–LEB). Through the Exploring for the Future Program, Geoscience Australia has completed the first regional hydrogeological assessment across this vast inland-draining catchment. Working across jurisdictional boundaries in SA, NSW, NT and Queensland has enabled us to generate significant new hydrogeological insights and develop enhanced knowledge of fundamental groundwater systems and processes, particularly within the KT–LEB's major depositional centres of the Callabonna and Tirari sub-basins, and the Cooper Creek Palaeovalley. New geological modelling has improved our understanding of the extent, depth and thickness of the Cenozoic sediment packages which host the basin's major hydrostratigraphic units, such as the Eyre Formation (regional aquifer) and Namba Formation (regional aquitard). Other investigation highlights include the development of the first whole-of-basin regional watertable trend and depth to groundwater maps and a major increase in the proportion of groundwater bores updated with information on hydrogeological province and/or source aquifer attribution. The key findings and outcomes of this study have illustrated the value of Geoscience Australia's approach to regional hydrogeological assessments, delivering consistent frameworks and enhancing the availability and quality of data and information to improve management and decision-making of Australia's major groundwater systems.</div><div><br></div><div>Citation: Lewis SJ, Evans TJ, Bishop C and Halas L (2024) Regional hydrogeological assessment of the Kati Thanda - Lake Eyre Basin, central Australia.

This service delivers the base of Cenozoic surface and Cenozoic thickness grids for the west Musgrave province. The gridded data are a product of 3D palaeovalley modelling based on airborne electromagnetic conductivity, borehole and geological outcrop data, carried out as part of Geoscience Australia's Exploring for the Future programme. The West Musgrave 3D palaeovalley model report and data files are available at https://dx.doi.org/10.26186/149152.
