The South China Sea is in the convergence zone of Pacific plate, Indo-Australian and Eurasian plate. Its formation tectonic evolution were influenced by continental margin spreading plate interaction between three plates their microcontinents. It has a complex geodynamic background. To understand how continents break up to form ocean basins, Basin taken as an example study dynamic mechanism its driving force seafloor spreading, so relationship oceanic–continental lithosphere plates. basin’s opening principal factors control remain controversial. explore influence different extension rates, we summarized genesis mechanisms Sea, combined with section basin, numerical simulation was obtained based on finite difference method. results from simulations show that rapid rate one important asymmetric expansion model, other such thickness rheological properties held constant. lithospheric mantle continued thinning stress concentration area, crust being pulled apart before mantle, eventually forming basin corresponding east sub-basin. However, when low, model expanded almost symmetrically, occurred at slow rate. confirm that, compared southwest sub-basin even higher. We believe subduction proto-South played crucial role providing more reasonable mechanism. opposite movement Kalimantan may have inhibited resulting later than sub-basin, well lower

The South China Sea, as 'a non-volcanic passive margin basin' in the Pacific, has often been considered a small-scale analogue of Atlantic. recent ocean drilling northern Sea found, however, that Iberian model rifted from Atlantic does not apply to Sea. In this paper, we review variety basins and propose discriminate two types rifting basins: plate-edge type such intra-plate like They only differ each other structure, formation process, lifespan geographic size, but also occur at different stages Wilson cycle. occurred Mesozoic gave rise large oceans, whereas took place mainly mid-Cenozoic, with three-quarters concentrated Western Pacific. As member Pacific system marginal seas, should be studied isolation on its origin evolution, systematic context include neighboring counterparts.

Abstract The tectonic evolution of the South China Sea is closely associated with multiple subduction-collision processes in Southeast Asia. When collision Dangerous Grounds terrane Sabah-Palawan Islands terminated debated due to poor age constraints at southern margin Sea.

Abstract Three‐dimensional seismic and well data from the deepwater Xisha Trough are used to investigate rift structure sediment infill of a region formed adjacently initial oceanic ridge South China Sea (SCS). The high‐quality permitted detailed analysis features such as (1) detachment faults soling out at Moho, (2) rotated thinned continental blocks covered by thick sediment, (3) changes in location basin depocenters resulting faulting. During rifting phase (Eocene earliest Oligocene), faulting was broadly distributed resulted generation isolated grabens/half grabens filled proximal sources. breakup Northwest Ocean Sector SCS (Oligocene), extension became restricted narrow where highly tilted thin crust were formed. Sediment was, that time, fed distal depocenters, which presently bounded listric rooted basal detachment. Later second stage (early Miocene), synchronously with Southwest SCS, study area blanketed sediment. two events, hyperextended affected closely spaced, small‐scale rather than large basement‐related structures. Our highlights effect way broaden influx multiple sources into basins. As corollary, this work recognizes distinct sequences concludes on their geodynamic significance SCS.

<p>The debate concerning the long-term evolution of East Asian summer monsoon (EASM) and its governing mechanisms persists, often attributed to either uplift Tibetan Plateau or global temperature changes. This disagreement arises from scarcity comprehensive, high-resolution records. Utilizing continuous sedimentary records South China Sea a weathering-rainfall-temperature regression model, we have quantified EASM rainfall in since 30 Ma. Our findings indicate that, apart notable sustained increase between approximately 21 13 Ma, patterns generally mirrored trends, suggesting that climate change was primary controlling factor. Based on model simulations, attribute anomalous enhanced during ~21‒13 Ma primarily dominant influence major Himalaya-Tibetan Plateau, with effects playing limited background role. topographic disrupted close coupling rainfall, resulting relatively humid habitable Asia despite ongoing cooling trend late Miocene. study clearly disentangles roles regulation short-term impacts Ma.</p>
