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.

The solid geology layers delivered in this web service were produced predominantly from interpretation of magnetic and gravity datasets, i.e. the Total Magnetic Intensity Grid of Australia (2019) – greyscale first vertical derivatives (1VD), and GA’s Complete Bouguer Gravity Anomaly Colour Composite Image of Onshore Australia (2016). These were calibrated with available drill hole data from state and territory geological surveys and GA databases, as well as with available solid and surface geology maps, particularly: 1) the GA's 1:1 M scale surface geology of Australia (2012), published 1:250 k scale map sheets, 2) Northern Territory Geological Survey geological maps (NTGS; 2000-2008), 1:500,000 scale regional solid/interpretation geology maps by NTGS (Pine Creek, 2005; Tennant Region, Donnellan N, and Johnstone A, 2004); 3) The Geological Survey of Queensland detailed solid geology and structure dataset (2018); 4) Basement Geology of Northern Queensland (Liu, 2009); 5) 2017 Canning Basin SEEBASE study and GIS data package (FROGTECH Geoscience, 2018), and 6) The Geological Survey of Western Australia 1:500,000 Interpreted Bedrock Geology of Western Australia (GSWA, 2016), 1:250,000 scale solid geology maps in the Kimberley area (Phillips, C, de Souza Kovacs, N, Hollis, JA, Eacott, GR and Maidment, D (compilers) 2018) and 1:250,000 scale solid geology maps in the Tanami-Arunta area (Eacott, GR, Haines, PW, de Souza Kovacs, N, Maidment, D and Spaggiari, CV (compilers) 2018). Interpretations were compiled at 1:250 k scale and the final product is best utilised at this scale.
