Structure of an active foreland fold and thrust belt, Papua New Guinea

Successive Rifting Events in Marginal Basins: The Example of the Coral Sea Region (Papua New Guinea)

“…The timing of the margin rifting is similar on the NW Shelf and Papuan New Guinea from the Late Permian to the Cretaceous and one can assume that there was a connexion between the basins nowadays jammed in the Papuan fold and thrust belts. Stratigraphic information are summarized from many sources among which (1) Geoscience Australia () and Ahmad and Munson (, ) for the Bonaparte and Arafura regions; (2) Bailly (2009), Bailly et al (), and Cloos et al () for the Lengurru and central Papuan region; (3) Home et al (), Hill and Hall (), Jablonski et al (), and Craig and Warvakai () for the Aure Fold Belt and the Papuan Basin; (4) Dow et al (), Struckmeyer (), Jablonski et al (), Hill and Hall (), Corbet (), De Smet et al (), and Sheppard and Cranfield () for the Northern Papuan Peninsula and Coral Sea Basin; and (5) Symonds et al (, ) and Struckmeyer et al () for the Queensland Trough. Abbreviations: AB: Arafura Basin, BB: Bonaparte Basin, CPFTB: Central Papuan fold and thrust belt, CSB: Coral Sea Basin, LFTB: Lengurru fold and thrust belt, NPP: Northern Papuan Peninsula, QT: Queensland Trough, and WPB: Western Papuan Basin.…”

“…Simplified stratigraphic column in the study area, including the Coral Sea Basin, the Aure fold belt, and Papuan fold belt. Stratigraphy and tectonic events are principally adapted from Home et al (), Jablonski et al (), and Craig and Warvakai (). Interpretation in the current study differs from these publications, namely, regarding the significance of tectonic events.…”

Synorogenic alluvial-fan – fan-delta deposition in the Papuan foreland basin: Plio-Pleistocene Era Formation, Papua New Guinea

“…Docking and compression were associated with faulting and uplift in the orogen, shortening in the Papuan-Aure Fold and Thrust Belt, and development of a second foreland basin in front of the fold and thrust belt and of successor basins within the orogen (Pigram et al 1989;Home et al 1990;Wang & Stein 1992;Crowhurst et al 1996). Fission-track analysis indicates uplift in the orogen in the Late Miocene-Pliocene (Abbott et al 1994;Crowhurst et al 1996;Hill & Raza 1999), and formation of the Papuan-Aure folds and thrusts primarily in the Pliocene (Abers & McCaffery 1988;Hill & Gleadow 1989;Craig & Warvakai 2009). Era Formation clastics ultimately were involved in the deformation.…”

“…Episodic rifting, formation of multiple subduction zones and island arcs, and development of the New Guinea Orogen were caused by complex plate interactions at the northern Australian Plate margin (Pigram & Davies 1987;Struckmeyer et al 1993;Davies et al 1996;Hill & Raza 1999;Quarles Van Ufford & Cloos 2005). Pliocene and Pleistocene convergence at the boundary was responsible for structural hydrocarbon traps in the Papuan Fold and Thrust Belt (Hill 1991;Barndollar 1993;Craig & Warvakai 2009). Tectonic evolution has been inferred in large part from rock exposures in Papua New Guinea; however, much of the geology of the country remains poorly documented because of the difficulty in working there.…”

Navigating the Future: An Ethnography of Change in Papua New Guinea

“…Having established a site from which Stanley's party could be serviced, Clancy now headed further east, crossed the Cecilia and cut southeast, to reach the Nomad River. He was establishing campsites and food stores that would be used by Stanley's team as they surveyed the Cecilia anticline (Craig and Warvakai 2009). It was only at his furthest campsite, beside the Nomad River, that Clancy met relatively large groups of men, women and children.…”
