“…The age of this small basin is highly controversial. Estimates vary from 131 to 119 Ma (Deschamps et al 2000) to 52-43 Ma for the northern part and Early Cretaceous for the southern part (Sibuet et al 2002), to 44-33 Ma (Hilde and Lee, 1984), 42-33 Ma (Doo et al 2015), or even ∼ 30-15 Ma (Kuo et al 2009). Further details and an interesting discussion about this controversy are available in Eakin et al (2015).…”

We compiled the most relevant data acquired throughout the Philippine Sea Plate (PSP) from the early expeditions to the most recent. We also analyzed the various explanatory models in light of this updated dataset. The following main conclusions are discussed in this study.(1) The Izanagi slab detachment beneath the East Asia margin around 60-55 Ma likely triggered the Oki-Daito plume occurrence, Mesozoic proto-PSP splitting, shortening and then failure across the paleo-transform boundary between the proto-PSP and the Pacific Plate, Izu-Bonin-Mariana subduction initiation and ultimately PSP inception. (2) The initial splitting phase of the composite proto-PSP under the plume influence at ∼54-48 Ma led to the formation of the long-lived West Philippine Basin and short-lived oceanic basins, part of whose crust has been ambiguously called "fore-arc basalts" (FABs). (3) Shortening across the paleo-transform boundary evolved into thrusting within the Pacific Plate at ∼52-50 Ma, allowing it to subduct beneath the newly formed PSP, which was composed of an alternance of thick Mesozoic terranes and thin oceanic lithosphere. (4) The first magmas rising from the shallow mantle corner, after being hydrated by the subducting Pacific crust beneath the young oceanic crust near the upper plate spreading centers at ∼49-48 Ma were boninites. Both the so-called FABs and the boninites formed at a significant distance from the incipient trench, not in a fore-arc position as previously claimed. The magmas erupted for 15 m.y. in some places, probably near the intersections between back-arc spreading centers and the arc. (5) As the Pacific crust reached greater depths and the oceanic basins cooled and thickened at ∼44-45 Ma, the composition of the lavas evolved into high-Mg andesites and then arc tholeiites and calc-alkaline andesites. (6) Tectonic erosion processes removed about 150-200 km of frontal margin during the Neogene, consuming most or all of the Pacific ophiolite initially accreted to the PSP. The result was exposure of the FABs, boninites, and early volcanics that are near the trench today. (7) Serpentinite mud volcanoes observed in the Mariana fore-arc may have formed above the remnants of the paleo-transform boundary between the proto-PSP and the Pacific Plate.

“…The original SCS basin before its subduction along the Manila Trench may have been twice the size that it is today (Sibuet et al, 2002), so geodynamic models must be able to explain the formation of this larger ocean basin. The Red River fault was active from 35 to 15 Ma, with displacement of as much as several hundred kilometers (e.g., Leloup et al, 2001;Gilley et al, 2003).…”

“…The Bashi Strait between Luzon and Taiwan is the only deep-water passageway between the modern semi-enclosed SCS and the open ocean, and the subduction zone of the Manila Trench is the edge where the SCS material is being "engulfed". Accordingly, the SCS basin should have been much broader and more open in the Middle Miocene when the spreading process just came to completing, the Philippines and many islands along the eastern border of the modern SCS were far in the south or unborn, and the area of the SCS basin then could be twice as large as today ( Figure 6) [88]. Therefore, the Manila Subduction Zone is a critical component in the SCS Deep research program.…”

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.
