  • Geognostics OZ SEEBASE depth‐to‐economic basement model of Australia and ancillary datasets. In this update, basement is defined as the top of igneous or metamorphic crust at the base of undeformed sediments, regardless of age. Note that in deeper parts of some basins, such as the greater McArthur Basin, the deepest section may be metasedimentary. Data provided by Geognostics, 2021. OZ SEEBASE® 2021 (Version 1, May 2021).
