“…Such distinct deformation of the post‐rift unit was likely caused by the compression of the late Miocene Longing Movement, resulting in thickening of the pre‐existing unit and the stacked growth strata of the upper post‐rift unit. Equivalent growth strata are also observed in the Xihu Depression (Li et al, ; Q. Wang, Li, Guo, Suo, & Dai, ). The deformational style of the reverse faults and fault‐related folds is similar to that of the Xihu Depression, forming a fold belt, called the Central Anticline Belt (G. Zhang et al, ; J. Zhang et al, ).…”

“…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.

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 oil–gas accumulation process is a tectonic indicator, and the oil–gas trap is generally a result of tectonic movement. In order to explore the law of oil–gas migration and accumulation in the East China Sea Continental Shelf Basin, this paper analyses the dynamic process of hydrocarbon accumulation based on a geological model, taking the Xihu Depression as an example and using the IES PetroMod basin modelling software. Combined with the seismic data and drilling data, the burial history, thermal evolution history and hydrocarbon generation, expulsion and migration history of the Xihu Depression is simulated in this study. The simulation results show that (1) the tectonic framework of the Xihu Depression developed as an inversion structure from an early extensional stage or transtensional faulting stage to a later compressional or transpressional inversion stage; (2) the Pinghu and Huagang formations of the Xihu Depression are still currently at the peak stage of oil–gas generation, and the Xihu Depression is a depression which has abundant hydrocarbon generation and expulsion at a later stage; (3) oil–gas resources vertically migrated to the structural highs from the eastern and western sub‐sags along faults and ultimately accumulated in favourable traps, which developed a migration pattern of interbedded sandstone–fault–sandstone like an upward ‘staircase’. In particular, faults and the potential energy state played an important role in hydrocarbon migration of the Xihu Depression, which has a guiding significance for understanding hydrocarbon migration and accumulation law and reducing the risk in oil–gas exploration in the East China Sea Continental Shelf Basin.

“…Fujiang) depressions, from southwest to northeast. Li et al (2008) examined early rifting styles of the Xihu Depression using deep seismic reflection, well logging and gravity data. They found that an initial rifting stage showing fast subsidence rates extended from the Paleocene to the Middle Eocene, and that the crustal layer beneath the central Xihu Depression was as thin as 6.5 km, equivalent to the typical thickness of oceanic crust.…”
