“…(4) From the end of Miocene to the present day, the convergence rate of the Pacific Plate continued to increase up to 100 mm/a and its motion sense was WNW (Zhang et al, 2016). At that time, the WDG was still in a relative uplifting stage.…”

Based on detailed analysis of the inversion tectonics in each of the secondary tectonic units of the East China Sea Shelf Basin (ECSSB), this paper suggests that the Cenozoic positive inversion tectonics in the basin are typically anticlines of various shapes associated with thrusts. Four stages of tectonic inversions are recognized in the basin related to the Oujiang Movement (T80), the Yuquan Movement (T30), the Huagang Movement (T20) and the Longjing Movement (T12), and these four inversion stages are temporally and spatially distinct. Temporally, the tectonic inversion in the West Depression Group tended to weaken, relatively, from the Oujiang Movement (T80) to the Huagang Movement (T20), while the Longjing Movement (T12) does not show an obvious inversion signature. Spatially, the Longjing Movement tectonic inversion in the Xihu and Diaobei sags of the East Depression Group shows a pronounced reduction in intensity from north to south. The tectonic inversion in the East Depression Group tended to intensify, relatively, from the Yuquan Movement (T30), through the Huagang Movement (T20) to the Longjing Movement (T12). The intensity distribution, migration and evolution of Cenozoic inversions in the ECSSB are local responses to the synthetic effect of the convergence and subduction rates, and direction changes between the Pacific and Eurasian plates and/or between the Indian and Eurasian plates. In particular, the eastward migration of positive inversion tectonics in the ECSSB is closely and successively related to the formation of the East Depression Group and the opening of the Okinawa Trough.

“…The ECSSB formed as a result of rift process controlled by the back‐arc extension or wrench tectonics related to the Indo–Asia collision (Allen, Macdonald, Xun, Vincent, & Brouet‐Menzies, ; Li, Zhou, Ge, & Mao, ; Lin et al, ; Ren, Tamaki, Li, & Junxia, ; Sibuet et al, ; Sibuet & Hsu, ; Suo et al, ; Yin, ; J. Zhang, Li, Suo, ). The basin subsequently experienced tectonic movements including the Oujiang, Yuquan, Huagang, and Longjing movements, related to the tectonic inversion in the ECSSB (Figure ; Q. L. Yang, ; Zhou et al, ).…”

Structural evolution of two‐stage rifting in the northern East China Sea Shelf Basin

This study focuses on the stratigraphic correlation and structural evolution of the Ieodo and Jeju basins in the northern East China Sea Shelf Basin (ECSSB), which are compared to the Changjiang and Xihu depressions, respectively. Based on multi‐channel seismic reflection data, Cenozoic sedimentary successions resting on the acoustic basement in both basins can be divided into multiple syn‐ and post‐rift units. Basement‐involved structures exhibit different orientations, that is, E–W (ENE–WSW) and NE–SW trending structures in the Ieodo and Jeju basins, respectively. They represent the development of two‐stage rifting. The first rift stage began in the Palaeocene and was only restricted to the Ieodo Basin located west of the Hupijiao Rise. The second rift stage subsequently occurred in the Jeju Basin located east of the Hupijiao Rise during the late Eocene to Miocene. The Eocene post‐rift unit of the Ieodo Basin was uplifted while the Jeju Basin was subsided by bounding faults. The sequential development of rift structures in the basins suggests eastward migration of the Cenozoic rifting in the northern ECSSB. The NE‐trending rift structure of the Jeju Basin parallel to the subduction zone of the Pacific Plate suggests that the second rift stage possibly evolved under the influence of the back‐arc extensional regime. The Hupijiao Rise between the Ieodo and Jeju basins was possibly a geologic basement in the Palaeocene and was an uplifted remnant caused by footwall exhumation during the second rift stage of the Jeju Basin.

“…The Zheming Volcanic Belt is similar to the East China Granite Belt, characterized by Yashanian intermediate‐acid intrusive and eruptive rocks (Li & Li, ; Niu et al, ; Zhou & Li, ). The continental shelf basin covers most of the ECS and is further divided into the West Depression, the Central Uplift, and the East Depression (Zhang, Li, & Suo, ; Zhang, Li, Suo, & Zhang, ). The sediments in the West Depression are mainly Paleogene.…”

Late Mesozoic transition from Andean‐type to Western Pacific‐type of the East China continental margin—Is the East China Sea basement an allochthonous terrain?

Geophysical features and crustal structure of the East China Sea basement were revealed based on geophysical inversion analysis with recent gravity and magnetic data. Our results show great differences between the East China Sea continental shelf basins and the Zhemin Volcanic Belt in the coastal South China Block with respect to geophysical features and crustal structures. These areas are separated by distinct geophysical and crustal changes, approximately along a line 100 km from the coastline of China. We hypothesize that the East China Sea basement is a buoyant allochthon in the Palaeo‐Pacific Plate, and that the East China margin was an Andean‐type active continental margin until the collision of the East China Sea basement with the South China Block in the Late Cretaceous, which jammed the Late Cretaceous Trench, terminating the subduction and the related granitoid magmatism. The East China continental margin was dominated by dextral transtension with limited magmatism due to the NNW‐trend motion of the Palaeo‐Pacific Plate with a reduced convergence rate until the Middle Eocene. The renewed westward subduction of the present‐day Pacific Plate replaced the East China Andean‐type continental margin with a Western Pacific‐type one. The detailed reconstructed tectonic model for the East China Sea since the Mesozoic is presented in this paper.
