Abstract Seismic reflection profiles and well data are used to determine the Cenozoic stratigraphic tectonic development of northern margin South China Sea. In Taiwan region, this evolved from a Palaeogene rift latest Miocene–Recent foreland basin. This evolution is related opening Sea its subsequent partial closure by orogeny. data, together with subsidence analysis deep wells, show that during rifting (∼58–37 Ma), lithospheric extension occurred simultaneously in discrete belts. These...
Seismic and well data suggest that the West Taiwan basin developed by orogenic loading flexure of a rift‐type continental margin. The most likely source is Taiwan, where oblique convergence between Eurasian Philippine Sea plates has produced an belt up to 300 km in length, 100 width, 4 height. Flexure modeling shows surface unable explain depth basin. Other, subsurface or buried loads are required. Combined explains width It also accounts for Bouguer gravity anomaly “high” flanking “low”...

Abstract Taiwan is an archetypal example of continental accretionary wedges. Yet the generally poor knowledge three‐dimensional strain distribution over time and role architecture rifted margin shed doubt on cylindrical two‐dimensional kinematic models collision. Here we provide new field‐based constraints distribution, Raman Spectroscopy Carbonaceous Materials temperatures apply mica‐chlorite multiequilibrium approach to determine pressure‐temperature in Central Range Taiwan.

Abstract Widely distributed bottom simulating reflectors (BSRs) imply the potential existence of gas hydrates offshore southwestern Taiwan. To compare distribution methane concentrations along passive and active margins in region, waters cored sediments were collected during four cruises from 2005 to 2006. The results reveal that sites with high are predominantly margin site GS5 is only contains very studied area. Anomalously fluxes still can be obtained calculation diffusive flux, although...
Abstract The northern part of the South China Sea is characterized by widespread occurrence bottom simulating reflectors indicating presence marine gas hydrate. Because area covers both a tectonically inactive passive margin and termination subduction zone, influence tectonism on dynamics hydrate systems can be studied in this region. Geophysical data show that there are multiple thrust faults active while much fewer smaller exist margin. This tectonic difference matches with geophysical...
Three giant piston cores, MD18-3548 (20.08 m), MD18-3552 (45.98 and MD18-3547 (35.27 were collected from perched basins in offshore SW Taiwan, with the objective of studying event beds. Detailed grain-size analysis (1 cm resolution), 14C AMS dating, X-CT-scan above-mentioned cores performed, lithofacies carefully delineated. Four distinct identified, namely hemipelagic sediments, homogenites a silty basal layer, turbidites, thin layers. Homogenites documented for first time they considerably...
An analysis of allogenic forcing on shallow-marine strata the Miocene–Pliocene Kueichulin Formation in Taiwan Western Foreland Basin shows that changes sedimentary record were predominantly driven by: 1) orogenesis and basin subsidence, 2) precession-driven hydroclimate, 3) obliquity-driven atmospheric ocean circulation.The transition from a wave-dominated open shelf to tide-dominated deltaic environment was influenced by combination subsidence denudation Taiwan. The rapid...
The South China Marginal Sea (SCS) is a Basin characterized by several failed continental rifts preceding break-up and subsequent seafloor spreading. oldest phase of rift propagation located in the northeast (NE SCS). We present new work constraining tectonostratigraphic evolution crustal structure this NE SCS margin, which we compare with that adjacent Pearl River Mouth Margin (PRMM). To achieve this, subsurface mapping from reflection seismic data was used together thickness determined...
The appraisal of sedimentary archives is key for predicting sea level changes and extreme weather event behavior under varying greenhouse gas levels. Here, we assess the hydroclimate variability northwest Pacific realm during Pliocene-Pleistocene transition by using a continuous record gamma-ray log data from two boreholes comprising shallow-marine strata in Western Foreland Basin, Taiwan. records provide high temporally resolved stratigraphic spanning ∼3.15 to ∼1.95 million years ago....
Abstract The continental margin to the east and south of China comprises an active in East Sea, a collision mountain belt Taiwan, passive South Sea. These three segments were generally regarded as separate tectonic entities their interrelations have long been subject debate. Here we synthesize available information outline geological background margin, examine link between Taiwan neighbouring margins, thereby establish Cenozoic evolutionary model. is floored with pre-Cenozoic basement...
Taiwan is an example of orogen involving a doubly vergent critical wedge. Critical-wedge theory predicts asymmetrical tectonic development the pro- and retro- sides orogen. Whereas consequences for exhumation, peak metamorphism, erosion have been extensively investigated, implications sandstone petrography preserved on either side not adequately documented. Plio-Pleistocene sandstones from Western Foothills were deposited in rapidly subsiding foreland basin recording collision between...
