The Perth Basin is the southernmost of a series of north-trending intracratonic rift basins initiated in the Late Paleozoic and extending along the western margin of Australia. The Lower Permian Irwin River Coal Measures consist of conglomerate, sandstone, mudstone, and coal organised in fining upward stratigraphic arrangements interpreted as fluvial- to tide-dominated marginal-marine and deltaic environments. Stratigraphic correlations show a retrogradational stacking pattern suggesting the progressive flooding of delta plains and embayments. Provenance analysis using detrital zircons indicate a major Archean sediment source (the Yilgarn Craton) and subordinate Proterozoic source terranes (the Capricorn and Albany-Fraser orogens, the Prydz-Leeuwin Belt).
