“…(2) Widespread early to middle Miocene strong compressional deformation, uplift, and erosion, sealed by an upper Miocene angular unconformity, is documented in the Shimanto fore arc of southwest Japan, especially documented in Kyushu, and in Okinawa [ Letouzey and Kimura , ; Raimbourg et al , ]. (3) Widespread Miocene compressive folding, uplift, and erosion at this time, capped by upper Miocene angular unconformities, is also documented in seismic images and drilling in the East China Sea, especially near the NW boundary of the Taiwan‐Sinzi belt with deep Cenozoic rift basins (Figure ) [ Cukur et al , , ; Gungor et al , ; Su et al , ]. Slow velocities and high anisotropic signatures from Rayleigh‐wave phase velocity analysis also suggests that the southern East China Sea lithosphere has been highly deformed [ Legendre et al , ].…”

We reconstructed Philippine Sea and East Asian plate tectonics since 52 Ma from 28 slabs mapped in 3‐D from global tomography, with a subducted area of ~25% of present‐day global oceanic lithosphere. Slab constraints include subducted parts of existing Pacific, Indian, and Philippine Sea oceans, plus wholly subducted proto‐South China Sea and newly discovered “East Asian Sea.” Mapped slabs were unfolded and restored to the Earth surface using three methodologies and input to globally consistent plate reconstructions. Important constraints include the following: (1) the Ryukyu slab is ~1000 km N‐S, too short to account for ~20° Philippine Sea northward motion from paleolatitudes; (2) the Marianas‐Pacific subduction zone was at its present location (±200 km) since 48 ± 10 Ma based on a >1000 km deep slab wall; (3) the 8000 × 2500 km East Asian Sea existed between the Pacific and Indian Oceans at 52 Ma based on lower mantle flat slabs; (4) the Caroline back‐arc basin moved with the Pacific, based on the overlapping, coeval Caroline hot spot track. These new constraints allow two classes of Philippine Sea plate models, which we compared to paleomagnetic and geologic data. Our preferred model involves Philippine Sea nucleation above the Manus plume (0°/150°E) near the Pacific‐East Asian Sea plate boundary. Large Philippine Sea westward motion and post‐40 Ma maximum 80° clockwise rotation accompanied late Eocene‐Oligocene collision with the Caroline/Pacific plate. The Philippine Sea moved northward post‐25 Ma over the northern East Asian Sea, forming a northern Philippine Sea arc that collided with the SW Japan‐Ryukyu margin in the Miocene (~20–14 Ma).

“…In particular, the East China Sea Shelf Basin (ECSSB) in the middle segment of the continental margin is one of the largest Meso‐Cenozoic oil‐gas‐bearing basins in offshore China. It is characterized by a ‘large basin area, low degree of exploration, rich oil‐gas resources and complex geological conditions’ and has attracted much attention from geologists and petroleum workers all over the world (Hilde et al ., ; Guo et al ., ; Jin and Shi, ; Jin, 1992a, 1992b; Feng et al ., ; Lee and Lawver, ; Isozaki, ; Song, ; Wu et al ., ; Xie et al ., ; Jia and Gu, ; Li and Mo, ; Robert, ; Zhou et al ., ; Feng et al ., ; Li et al ., ; Liu et al ., ; Wang and Zhang, ; Feng and Cai, ; Maruyama et al ., ; Yang et al ., ; Cukur et al ., , ; Li et al ., ; Suo et al ., , , ; Guo et al ., ; Jiang et al ., ; Niu et al ., ).…”

The East China Sea Shelf Basin (ECSSB) is located on the southeastern continental margin of the Eurasian Plate. The basement of the ECSSB is an extension of the Cathaysian Block as well as an important part of the West Pacific or East Asian Continental Margin tectonic domain. By the analysis of global plate tectonic evolution, the ECSSB is situated in the eastern part of the West Pacific triangle region, as a huge convergence zone between the Indian‐Australian, Pacific and Eurasian plates, as well as a global convergence centre. The ECSSB is closely related to the evolution of the Tethyan and West Pacific tectonic domains. Overall, the ECSSB is a pull‐apart basin under the transtensional tectonic setting of a continental margin, which is contributed to by the combination of subduction retreat and back‐arc spreading between the Eurasian Plate and the Pacific Plate, and the far‐field effect of the collision and extrusion between the Indian‐Australian and Eurasian plates, and deep mantle dynamics. The formation mechanism of the ECSSB is under passive extension. The eastward mantle flow and the asthenospheric upwelling in the deep Earth are the main driving forces of the basin jumping and eastward tectonic migration. Copyright © 2016 John Wiley & Sons, Ltd.

“…The East China Sea Shelf Basin (ECSSB) is one of the major Meso–Cenozoic sedimentary basins in the Chinese offshore area, located in the convergent zone between the Eurasian, Pacific and Philippine Sea plates. The zone is a typical subduction‐type plate margin (Cukur et al ., , ; Zhang et al ., ) consisting of the following structural units from west to east: Zhemin Ridge, ECSSB (Lishui, Fuzhou and Xihu depressions), Taiwan‐Sinzi Fold Belt, Okinawa Trough, Ryukyu Arc, Ryukyu Trench and Pacific Ocean (Fig. A and C).…”

Change from tide‐influenced deltas in a regression‐dominated set of sequences to tide‐dominated estuaries in a transgression‐dominated sequence set, East China Sea Shelf Basin

The East China Sea Shelf Basin was a back‐arc basin located at the active continental margin of the western Philippine Sea Plate. This study explores facies and architectural changes from tide‐influenced deltas to tide‐dominated estuaries in transgressive–regressive cycles, as well as their controlling factors. Cores, wireline well‐logs and seismic data allow the sedimentary architectures and models of the depositional systems to be reconstructed. In the Xihu Depression of the East China Sea Shelf Basin, the stratigraphic sequences of the Eocene Pinghu Formation are interpreted to be dominated by repeated phases of deltaic progradation, but with intervening transgressive phases only thinly developed as bioturbated, open‐marine shelf deposits. The sequences of the overlying Oligocene Huagang Formation, in contrast, are interpreted as stacked, tide‐dominated estuary units, alternating with only poorly preserved regressive half‐cycles because of repeated, strong estuary down‐cutting. The intervening unconformity in the succession corresponds to the Yuquan tectonic movements, which triggered a change from extensional to compressional settings in the Xihu Depression. In the Late Eocene, extension of the Xihu Depression led to moderately high rates of subsidence (163 m Ma−1), and short‐term sea‐level falls led to multiple phases of deltaic progradations. After the Yuquan Movement, Early Oligocene compression brought overall lower rates of subsidence (110 m Ma−1), as well as sea‐level rise and stacked estuary development with significant tidal influence in the infill. The interaction of tectonics, sea‐level change and sediment supply determined the nature of the depositional systems on the shelf during the entire period, whereas the sedimentary processes were key to reworking and shaping the facies distribution, geomorphology and architectures in the back‐arc basin. This research provides an insight into spatial and temporal characterization of deltaic and estuarine systems, contributing to a better understanding of the mechanisms controlling a change in dominant coastline type, despite continued strong tidal influence.
