This chart is a modified compilation of the stratigraphy of the offshore basins along Australia's northwestern and northern margins from the Northern Carnarvon Basin in the south to the Carpentaria Basin in the north based on AGSO's previously published Basin Biostratigraphy Charts 1, 3, 7, 11, 14, 15 & 16 (1996 - 1998). The chart shows the stratigraphic position of AGSO's interpreted regional seismic horizons.

Geoscience Australia's Basin Biozonation and Stratigraphy Chart series is a compilation of Australian hydrocarbon-bearing basin charts. Each chart summarises a basin's lithostratigraphy, hydrocarbon shows/discoveries and source rocks, correlating each basin sub-division with the international timescale, relevant biozones and a global sea level curve.

Biostratigraphy is the branch of stratigraphy that uses fossils to establish relative ages of rock and correlate successions of sedimentary rocks within and between depositional basins. A biozone is an interval of geologic strata characterised by certain fossil taxa. Such intervals are often defined by the first appearances (range bases), apparent extinctions (range tops/last appearances), or abundances of fossil index species. These key index species should be relatively abundant, short-lived taxa that are easy to recognise and as geographically widespread as possible. Widely used fossil groups include brachiopods, conodonts, dinoflagellate cysts, foraminifera, graptolites, nannofossil, spores and pollen and trilobites. Zonal schemes based on several different fossil groups can be used in parallel, and the zones can be calibrated to the absolute geological timescale using tie points to rocks which have been radio-isotopically dated.
