“…Figure d shows a north‐south seismic section from the southern end of the foreland basin, which is the most distal part of the basin from terrigenous source areas of the Fly Platform [ Tcherepanov et al ., ]. Foreland basin sediments in this area are ∼1.6 s TWT thick (∼2 km), or about 30% of the thickness observed in the northern part of the foreland basin (Figure a).…”

The Aure-Moresby fold-thrust belt and Aure-Moresby foreland basin are located in the eastern Gulf of Papua (GOP), Papua New Guinea (PNG), and formed during late Miocene-Recent as the result of large-scale, counterclockwise rotation of the 355,000 km 2 Woodlark microplate. To document the structure, stratigraphy, and age of convergent deformation along the poorly studied, western edge of the rotating Woodlark microplate, we integrate results of 2,538 km of previously unpublished 2-D seismic reflection data with onshore geologic and GPS studies from previous workers. The late Miocene Aure-Moresby fold-thrust belt is a 400 km long, northwest-trending fold-belt exposed onshore in Papua New Guinea that plunges to the southeast, where continuous folds and northeast-dipping thrusts can be imaged in the subsurface for more than 250 km. The arcuate trend of the Aure-Moresby fold-thrust belt along the southwestern coast and offshore areas of the Papuan peninsula parallels the shape of the adjacent, offshore Aure-Moresby foreland basin and the strike of the transpressional segment of the leftlateral Owen-Stanley fault zone (OSFZ) passing along the center of the Papuan peninsula. As the OSFZ becomes more transtensional east of 1488E, folds of the Aure-Moresby fold-thrust belt along southern coast of the peninsula become less prominent, and the adjacent Aure-Moresby foreland basin transitions into an undeformed Cenozoic passive margin setting. These observations of convergent an left-lateral deformation along the Aure-Moresby fold-thrust belt are consistent with: (1) counterclockwise rotation of the Woodlark microplate known from regional GPS studies; (2) coeval opening of the Woodlark basin along its southern edge in the late Miocene; and (3) rapid subduction at the New Britain trench along its northern edge. The kinematics of the rotating Woodlark microplate are driven by slab pull forces acting on the actively subducting northern edge of the microplate.

“…10). This timing for collision is further evidenced by a contemporaneous switch in sedimentation patterns in the Gulf of Papua (Tcherepanov et al, 2010). Prior to the Late Miocene, sedimentation on the northern Australian platform was characterized by carbonates; this is in contrast to siliciclastic deposition in the Aure trough (Pocklington trough) at the same time.…”

“…Prior to the Late Miocene, sedimentation on the northern Australian platform was characterized by carbonates; this is in contrast to siliciclastic deposition in the Aure trough (Pocklington trough) at the same time. Subsequent to continent collision, the Late Miocene to Early Pliocene is marked by cessation of sedimentation in the Aure trough coupled with the initiation of siliciclastic sedimentation in the Gulf of Papua (Pigram and Symonds, 1991;Tcherepanov et al, 2010) implicating closure of the Pocklington trough and the bypass of sediments over the continental Fly Platform. We interpret that…”

Continental collision, orogenesis and arc magmatism of the Miocene Maramuni arc, Papua New Guinea

The Maramuni arc represents the only continuous record of the tectonic evolution of Papua New Guinea during the Miocene, and hence provides an opportunity to gain insight into subduction dynamics, orogenesis and crustal processes that operated throughout this dynamic period. We present an integrated U-Pb geochronology, Hf isotope and geochemical investigation of the Maramuni arc utilizing a suite of intrusive rocks from the Kainantu region of the eastern Papuan Highlands that span the Late Miocene from ca. 12 Ma to 6 Ma. The magmatic rocks formed from ca. 12-9 Ma have compositional affinities of subduction-zone magmas, but record increasing incompatible trace element contents and decreasing εHf with time, which we interpret to reflect a progressive increase in the crustal component of the magmas. Porphyry suites emplaced at 7.5-6 Ma are distinct from the older magmatic rocks by their marked HREE-depletion, which reflects a dramatic shift in arc-mantle dynamics. Based on these results we propose a revised geodynamic model for the tectonic

“…Synorogenic depositional systems and sediment routing are based on Galloway and Brown (1972), Brown et al (1973), Palacios Albujar (2018 and Hentz and Ambrose (2019). Postorogenic depositional systems and sediment routing are based on Handford (1980a), Handford (1981), Mazzullo et al (1989) and Waite et al (2020) significantly influenced by eustatic fluctuations (Tcherepanov et al, 2008), all stages of major shelf progradation resulted from tectonic-related siliciclastic influx from Papua New Guinea (Tcherepanov et al, 2010). The fastest shelf progradation is linked to late-Pliocene renewed uplift and exhumation of Papuan Peninsula, enhanced by the Pliocene global warming and East Asian monsoons.…”

Tectonic controls on the evolution of mixed carbonate‐siliciclastic systems: Insights from the late Palaeozoic Ouachita‐Marathon Foreland, United States

Sea level is thought to be the primary driver of alternating deposition of carbonate and siliciclastic sediment in shelf settings, with carbonates dominating during transgressive/highstands and siliciclastics during lowstands. Although sediment supply is critically important for shelf-margin growth in siliciclastic systems, few studies demonstrate its impact on mixed carbonate-siliciclastic systems. The Permian Basin in Texas, United States, provides an opportunity to investigate the basin evolution regarding the source, sediment routing and particularly shelf/slope growth from synto postorogenic phases during alternating carbonate and siliciclastic sedimentation.Published detrital zircon data show that the proportion of orogen-related sources decreased significantly from an earliest Permian synorogenic phase (ca. 298 Ma) to a Leonardian (ca. 280-271 Ma) postorogenic phase, in concert with a grain-size change from fine-to medium-grained sand to silt. Although along-strike lateral variabilities exist on the shelf margin, the shelf-margin evolution characteristics show a significant difference among the Northern Shelf, Eastern Shelf and Central Basin Platform. The synorogenic Eastern Shelf exhibits a significant higher progradation rate than does the postorogenic Northern Shelf. The progradation and aggradation ratio of siliciclastic-rich intervals in the Eastern Shelf is significantly higher than those of carbonate-rich intervals in the Eastern Shelf and carbonate-or siliciclasticrich intervals in the Northern Shelf. In contrast, the Central Basin Platform, with no siliciclastic sediment supply, records almost no progradation regardless of orogenic phases. There is an increase in slope gradient with decreasing sediment supply during this second-order sequence from the Permian Cisuralian Series to the end of the Guadalupian Series. This study demonstrates that tectonically driven siliciclastic sediment supply was the main mechanism controlling the shelf and slope evolution in alternating siliciclastic and carbonate deposition.
