Graph probability distribution plot of the composite detrital zircon age spectra of formations from the Maiwok Subgroup, Collara Subgroup, South Nicholson Group, Inorunie Group and sedimentary rocks from the Millungera Basin (Fig. 1), illustrating the provenance similarity between these basins. The plot was generated using the FitPDF program (Eglington, 2018). Probabilities are illustrated by the colour density. MDA: maximum deposition age; Gp: group; Fm: formation. Red lines represent assigned maximum deposition age for each formation. Red dashed lines represent possible maximum deposition age constraint.

Tectonic and paleogeographic reconstructions presenting the model that accounts for the geology observed in the Georgetown Inlier (GI, northeast Australia). Detrital zircon age spectra from the Georgetown Inlier are presented to compare with age equivalents from the Mount Isa Inlier (MI) of northeast Australia and the Wernecke Supergroup of the Yukon Territory, northwest Canada (Carson, 2013; Furlanetto et al., 2016; Neumann et al., 2009, 2006). A and E: Ca. 1700 Ma. Sediments in the Georgetown Inlier were initially deposited in a passive margin while sediments in the Mount Isa Inlier were deposited in a backarc basin to a west-dipping subduction zone (Betts et al., 2016). NAC—North Australia craton; SAC—South Australia craton; He—Hearne craton, Sl—Slave craton. B and F: Ca. 1650–1620 Ma. Development of an east-dipping subduction zone off the western margin of Laurentia prompted backarc rifting between the Georgetown Inlier and Laurentia causing complete separation by ca. 1650 Ma. WS—Wernecke Supergroup. C and G: Continued subduction leads to accretion of the Georgetown Inlier to the North Australia craton (NAC) (Isan-Jana orogeny) and the Racklan orogeny in west Laurentia. D and H: Post–1550 Ma. Detrital zircon age spectra from the Inorunie Group strongly resembles the Constance Sandstone of the Mount Isa Inlier, suggesting a correlation and further indicating a connection after1550 Ma.
