...Ryan T. Tucker; Eric M. Roberts; Robert A. Henderson; Anthony I.S. Kemp Abstract U-Pb geochronology and Lu-Hf isotope analysis of detrital zircon from the mid-Cretaceous Winton and Mackunda Formations in the Eromanga Basin were employed to investigate regional provenance patterns in order to better...

... in the Whitsunday Volcanic Province to the east that was carried west as sediment loads by rivers ( Bryan et al. 1997 , 2000 , 2012 ; Tucker et al. 2013 ). The Winton Formation conformably overlies the shallow marine Mackunda Formation and unconformably underlies poorly consolidated Quaternary sands, silty...

... of the fault system and of individual faults is based principally on analysis of three mapped horizons (Top Cadna‐owie Formation (oldest), Top Coorikiana Sandstone, and Top Mackunda Formation) within the Lower Cretaceous sequence ( Fig. 1b). These three horizons span a stratigraphic thickness of c.  550–700 m...

... normal compaction trend. The Mackunda Formation is the uppermost preserved unit of the Eromanga Basin in the study region. The Winton Formation ( Figure 2 ), a depositional unit of significant thickness (∼900 m [∼2950 ft]) in the adjacent Cooper Basin ( Deighton et al., 2003 ), is patchily preserved...

...) is coeval with Albian units in the GAB (e.g., Mackunda Formation), offering a comparison of any potential contemporaneous distal versus proximal material derived from the W-SLIP. Subsequently, a thick sedimentary succession accumulated in the eastern Bight Basin in the mid- to late Cretaceous as rifting...

... from density inversion. It appeared in the mudstone sequence from the Cadna-owie formation to the Mackunda formation [ 72 – 74 ]. (a) The Cadna-owie formation developed a 35 m thickness and low-density mudstone. (b) The overlying mudstone of the Cadna-owie formation rapidly deposits, which hinders...

... is whether or not this type of fault system is generated by a density inversion beneath the faulted sequence. Our model is similar to that of Henriet et al . (1991), who also attribute the formation of folds and faults to density inversion, but it differs significantly from the model of Cartwright...
