Neogene deformation along the northern margin of Australian Plate changes character, from a collisional to east in Timor Sea passive further west Carnarvon Basin. Changes style reflect changing regional stress. The continental collision currently underway vicinity Island (the Banda Orogen) influences adjacent Sea, but has little effect location also changes, outboard inboard Basin, with neotectonic events strongly controlled by basement boundaries We propose that and Browse Basin can be...
Ages varying from Late Triassic to Early Jurassic have been proposed by different authors for the onset of rifting in Northern Carnarvon Basin. Seismic sections Exmouth Sub-basin and outer Plateau demonstrate significant growth strata associated with displacement on normal faults starting at least base R. rhaetica zone (Rhaetian). This tectonic event coincides a marked change sequence architecture large landward shift (~300 km) paleo-shoreline vicinity Rankin Alpha Arch trends. Rapid...
Deformation of trench-fill sediments at the central Japan Trench axis confirms that coseismic slip during 2011 CE Mw 9.1 Tōhoku-oki earthquake extended to shallowest part megathrust fault, contributing unexpectedly large tsunami followed. Understanding recurrence “slip-to-the-trench” style earthquakes is therefore essential for diagnosing future hazard (and other subduction zones). Thermal biomarkers from décollement indicate similar shallow has occurred repeatedly, but timing not yet been...
ABSTRACT Deep-sea and subseafloor sedimentary environments host heterotrophic microbial communities that contribute to Earth’s carbon cycling. However, the potential metabolic functions of individual microorganisms their biogeographical distributions in hadal ocean sediments remain largely unexplored. In this study, we conducted single-cell genome sequencing on sediment samples collected from six sites (7,445–8,023 m water depth) along an approximately 500 km transect Japan Trench during...
The International Ocean Discovery Program (IODP) Expedition 386, Japan Trench Paleoseismology, represents the first utilization of giant piston coring (GPC) within scientific ocean research drilling. This allowed for a Mission Specific Platform (MSP) multi-site, multi-hole, shallow subsurface in an ultra-deep water subduction zone trench. primary objective expedition was to investigate concept submarine paleoseismology Trench, which involves studying long-term records deposits deep sea that...
Abstract Neogene collision between Australia and the Banda Arc modified two adjacent depocentres within Australia's North‐West Shelf, Browse Bonaparte Basins. We identify components of this modification: (1) continuous long‐wavelength amplification Permo‐Carboniferous basement topography, (2) flexure normal faulting Triassic–Recent sedimentary cover. Although deformation was across Basins, degree architectural control, mechanisms fault linkage distribution syntectonic accommodation space...
Abstract Hadal trenches are unique geological and ecological systems located along subduction zones. Earthquake-triggered turbidites act as efficient transport pathways of organic carbon (OC), yet remineralization transformation OC in these not comprehensively understood. Here we measure concentrations stable- radiocarbon isotope signatures dissolved inorganic (DOC, DIC) the subsurface sediment interstitial water Japan Trench axis collected during IODP Expedition 386. We find accumulation...
The Bonaparte Basin (NW Australia) forms a rare, recent example where Neogene deformation shaped very wide platform (630 km wide) in which mixed carbonate-silliciclastic sedimentary sequence developed. This study combines structural and stratigraphic analysis provides new insights as to the role of tectonics controlling shape sediment distribution shallow water settings. Detailed structure stratigraphy northern part allowed identification main regimes phases their control on sedimentation...
Neogene collision between the Australian, Eurasia and Pacific plates was coeval with growth of major depocentres in Timor Sea. Seismic cross-sections across these troughs identify a characteristic architecture: all three lie inboard diffuse horst-like structural highs mimic older depressions top-Permian upper-Jurassic surfaces. Distortion pre-tectonic (Aptian–Oligo-Miocene) sequences indicates apparent trough subsidence coupled to uplift outboard highs. Rudimentary cross-section restoration...
The Barcoo Sub-basin forms the southern part of Browse Basin Australia’s northwestern margin. Miocene reactivation older Precambrian through Mesozoic-aged structures has resulted in a present-day complex right-lateral wrench zone. fault system displays restraining and releasing bends separated by areas almost pure strike-slip displacement, along its 180 km length. Reactivation inversion varies system, with end structurally highest, offsetting beds up to including seafloor. location controls...
The interrelations between stress orientation, regional deformation, and seismic activity in the context of intraplate seismicity continue to pose difficult questions. Stress models Australian continent are largely based on nonseismic information. Our study 26 microearthquakes NW Australia shows that they good indicators seismogenic field. By inverting focal mechanisms calculated from events we obtained deviatoric tensors full agreement with known in‐situ corroborate elastic modeling...
Mount Mundo Perdido, a 1750 m-high, steep-sided massif situated in the Viqueque district of East Timor, comprises approximately 30 km2 complexly juxtaposed rocks deriving from both sides collisional plate boundary between Australian Plate and Banda Arc. Lithologies include Triassic–Jurassic interior-rift basin deposits, Cretaceous–Oligocene pelagites passive margin origin, neritic Oligocene–Miocene limestones volcanics Asiatic affinity, Pliocene–Pleistocene synorogenic deposits.
