“…Significant subsidence started by the end of the Middle Miocene, which brought about the deep-water environment up to the present ( Figure 5(c)). These records indicate a much later spreading in the SW than in the N part of the SCS, supporting the "hybrid tectonic model" which claims that spreading in the SE Sub-Basin in the Miocene was driven by subduction towards Borneo, when the spreading axis was propagating toward SW with accompanying active magmatism [24]. These new observations clearly show that different paces of evolution in the two Sub-Basins controlled the different histories of marine sedimentation in these areas.…”

the first large-scale basic-research program in ocean science in the country aiming to reconstruct the life history of a marginal sea. The overall scientific objective of the program is to dissect this typical marginal sea by studying its history of evolution and its modern processes, including the following three major components: (1) Development of the deep basin: utilizing new techniques to re-measure magnetic anomaly lineations, to explore the deep tectonic features, to drill the oceanic crust, and to study volcanic seamount chains; (2) deep-water sediments: observing the modern processes to reveal the patterns of deep-water circulations and sedimentation, analyzing deep-sea sediments to recognize paleoceanographic response to basin evolution, and subsequently to bridge the modern and paleo-studies of the deep-sea processes; and (3) biogeochemical processes: using a variety of techniques including deploying submarine observation and deep-water diving device to investigate the distribution patterns and environmental impacts of deepwater seepages and subbottom circulation, and to reveal the role of microbes in deep-sea carbon cycling. As compared with the open ocean and other marginal seas, the South China Sea enjoys many more advantages as a marine basin for reconstructing the life history. Meanwhile, the South China Sea Deep Program provides unique opportunities in studying the evolution and variations of the sea-land interactions between the Pacific and Asia.the South China Sea Deep, marginal sea, deep-sea process, life history, tectonic evolution, sedimentological response, biogeochemistry Citation:Wang P X.

“…Also, Early to MidCretaceous granitic rocks were collected from a number of drilling wells over the Dongsha Islands' northwest area (Chen et al, 2003;Shi et al, 2011 and references therein) and from two dredges on the boundary cliff of the northwestern Nansha Island block that faces the SW oceanic sub-basin (Qiu et al, 2008;Yan et al, 2010). Yanshanian granitic basement was also found over Cuu Long and Meikong Basins offshore South Vietnam (Areshev et al, 1992;Fyhn et al, 2009;Lee et al, 2001). All these lent more support for the hypothesis of the Mesozoic Andean arc, and constrained it further southeast into the offshore area.…”

“…They can also be important for hydrocarbon exploration, because some reefs and carbonate platforms are highly porous and host nearly one half of the world's hydrocarbon reserves, containing some of the largest aquifers on the Earth (Sun and Esteban 1994;Groetsch et al 1998;Wu et al 2008;Sattler et al 2009). Due to geological and geophysical data acquired in the last decades, Cenozoic shallow water carbonates in the South China Sea have been well documented on its (1) detailed seismic features, stratigraphic architecture, and controlling factors in local regions, such as the northern rim of the Dongsha Islands (Tyrell and Christian 1992); the western Pearl River Mouth Basin (Sattler et al 2009); the Qiongdongnan Basin (Wu et al 2008;Ma et al 2011) in the northern continental margin of the South China Sea; the Phu Khanh Basin (Fyhn et al 2009), the offshore of central Vietnam (Fyhn et al 2013) in the western continental margin; the Dangerous Grounds (Ding et al 2013;Franke et al 2013) in the southern continental margin; and (2) regional time-space distributions, control processes and geologic evolution model (Wilson et al 2000;Xu et al 2002;Madden and Wilson 2013).…”

We have analyzed two recently acquired multichannel seismic profiles across the Reed Bank area, South China Sea. A detailed seismic interpretation coupled with drilling data has proved the occurrence of a wide carbonate platform, developed between the Late Oligocene and the Early Miocene (32-20 Ma). The top of these carbonates is an important regional unconformity, corresponding to a strong and continuous seismic reflector. An age of about 20 Ma is inferred for this reflector, acting as a regional unconformity marking the cessation of seafloor spreading with an erosional/non-depositional hiatus, spanning 3 or 4 m.y. The time interval during which the carbonate platforms formed is concurrent with the opening of the South China Sea. The reconstruction of the tectonic subsidence in this area has shown a decrease in rate of subsidence during the drifting stage (32-17 Ma), indicating that the whole Reed Bank area was in a tectonically stable and shallow water environment for more than 10 m.y., favoring the development of shallow water carbonates. With a sharply increased subsidence rate after the end of spreading (17 Ma) and a continuously increased sea level, the carbonate platforms were drowned and died, except some structural highs with reef buildups, where the carbonate sedimentation continued to Middle Miocene. We suggest that delayed tectonic subsidence in Reed Bank area might have been related to a secondary mantle convection under the rift lasting more than about 10 m.y.
