Seamless chronostratigraphic solid geology of the North Australian Craton
Geological maps are one of the most important datasets used in resource exploration and management. Despite increasing demand for subsurface resources such as minerals, groundwater and energy, maps of the inferred subsurface geology of Australia and other continents have been limited to small regions or jurisdictions. Here, we present the first seamless semi-continental chronostratigraphic solid geology dataset of the North Australian Craton. This dataset comprises five time slices of stratigraphic units: Cenozoic, Mesozoic, Paleozoic, Neoproterozoic and pre-Neoproterozoic. Interpretation of covered units is based on available data: surface geology and solid geology maps, magnetic intensity and gravity images, drilling logs, reflection seismic profiles and airborne electromagnetic soundings. In total, 2008 units have been mapped, all linked to the Australian Stratigraphic Units Database. So far, these maps have led to a refinement of sedimentary basin and tectonic province outlines, lessened the risks of mineral exploration through Australia’s extensive superficial cover, disclosed geological units known to host resources elsewhere, and highlighted undercover regions with poor geological constraints.

- Statement
-
This is the first seamless solid geology dataset of the North Australian Craton, comprising five time slices of Cenozoic, Mesozoic, Paleozoic, Neoproterozoic, and Pre-Neoproterozoic age. It is based on pre-existing surface geology and solid geology maps, magnetic intensity and gravity images, drilling logs, reflection seismic profiles, and airborne electromagnetic soundings, and is essential in resource exploration for minerals, energy, and groundwater in areas concealed below superficial cover such as deserts, alluvial plains, vegetation, etc.
