“…The South China Sea (SCS) is the largest marginal sea in the world, with an area of about 3.5 million km 2 , and has been a hot topic among geologists in China and western countries Zhou et al 2011;Xu et al 2012;Huang et al 2013;Li et al 2014a;Liu et al 2014;Tang et al 2014;Clift et al 2015;Lei et al 2015). Tectonically, the SCS is located at the junction of the Eurasian, Indian, Australian, and Pacific Plates and its formation is commonly attributed to interactions among these plates (Sun et al 2006;Xia et al 2006).…”

Different models have been proposed for the formation and tectonic evolution of the South China Sea (SCS), including extrusion of the Indochina Peninsula, backarc extension, two-stage opening, proto-SCS dragging, extension induced by a mantle plume, and integrated models that combine diverse factors. Among these, the extrusion model has gained the most attention. Based on simplified physical experiments, this model proposes that collision between the Indian and Eurasian

“…The white dotted lines represent the boundary of the Yinggehai-Song Hong Basin. The depositional environments changed from neritic to neritic-littoral in the Pliocene and to littoral in the Pleistocene (Lei et al, 2015). The red dots indicate the Cenozoic sediments in the Hanoi Basin and Panzhihua area studied by Clift et al (2008) and Zhang et al (2017), respectively.…”

The development of the Red River is closely related to the topographic changes in East Asia, but the evolution of this drainage system remains unclear. We determined Pb isotopic compositions of detrital K‐feldspars from the Yinggehai‐Song Hong Basin to understand the sedimentary provenance and to test models of drainage patterns in East Asia. The Pb isotopic data show that detritus in the northern basin was mainly derived from the Red River system since the late Oligocene, and that the Red River achieved its present state in the late Miocene (~10.5 Ma). The variable provenance over time suggests that the Red River was probably connected to the Middle Yangtze and Mekong Rivers before the Miocene, and lost these headwater areas in the middle and late Miocene, respectively. The drainage reorganization probably occurred in response to rapid surface uplift of eastern Tibetan Plateau.

“…The Eocene‐Oligocene restored position of the basins in this area would locate them close to the Xisha Trough (Gao et al, ) and other hyperextended basins (Figure , green areas) that were abandoned on the northern margin, suggesting that all these basins are genetically linked. At variance with Xisha Trough, which shows important accumulation of Cretaceous and Tertiary sediments and occurrences of mantle or magmatic intrusions (Lei et al, ), stretching was less severe in these southern basins since mantle was not exhumed.…”

We investigate the crustal structure of the Dangerous Ground (South China Sea) through processing and interpretation of coincident wide‐angle reflection and refraction seismic data. Continental crust of Dangerous Ground has been moderately thinned, down to 15 km, so that most of the structures accompanying the early opening of the South China Sea from Cretaceous to Miocene have been preserved. Subbasement reflectors as well as refraction velocities image an interpreted dismantled Mesozoic metamorphic unit in the southernmost section of our study area. A rollover structure indicates that the reflective base of the unit was used as a décollement where low‐angle normal faults root and blocks rafted. The metamorphic unit is discontinued in a nearby basin located immediately to the north, where the refraction velocity model shows thinning of the crust from 20 to 15 km, with the presence of a 5‐km‐high mantle dome. In this deeper basin, mass transport deposits are found lying on a strong amplitude basement reflector interpreted as the footwall of an ~15 km offset crustal detachment surface that we link down to the mantle dome. We infer that the detachment reactivated an inherited low‐angle contact most probably related to the Yanshanian belt. In map view, the reactivated structure forms a half‐graben basin oriented NNE‐SSW oblique to the generally accepted direction of extension. This orientation follows the general trend of a granitic belt that spanned the South China margin prior to extension, related to the subduction of the Paleo‐Pacific.
