“…The Subei‐Southern South Yellow Sea basin consists of the Subei basin and the Southern South Yellow Sea basin. Although the Subei basin and the Southern South Yellow Sea basin, separated by the shoreline, are located in onshore and offshore areas, respectively, they belong to the same basin . The Subei‐Southern South Yellow Sea basin, with a total area of 4.5 × 10 4 km 2 , is bounded to the west by the Tanlu fault, to the north‐west by the Huaiyin‐Xiangshui fault, to the north by the central uplift of South Yellow Sea basin, and to the south by the Zhangbaling uplift, the Tianchang uplift, the Tongyang uplift, and the Wunansha uplift (Fig.…”

An understanding of CO2 sources, sinks, and their optimal matching relationships is helpful when making an initial assessment or making decisions regarding CO2 sequestration. One of the most populous and developed provinces in China, Jiangsu, is facing tremendous pressure to reduce CO2 emissions. This study assessed CO2 emissions from large, stationary CO2 sources and the CO2 geological storage capacity for the Jiangsu province, and studied their optimal geographical matching relationships. The results of the study show that major, large, stationary sources have a total of 730.75 Mt/year CO2 emissions, and the majority of them are located in southern Jiangsu. The Subei‐Southern South Yellow Sea basin, with a total storage capacity of 5.21 × 104 Mt, can be subdivided into 28 storage blocks based on the faults. Source‐sink geographical matching shows that the locations of the sources and the matched sinks are approximately translational. When the entire Subei‐Southern South Yellow basin was chosen as an option for CO2 sinks, the sinks that matched to the northern Jiangsu CO2 sources were mainly located in the onshore northern Subei basin. The northern sources tended to match the north sinks of the northern Subei basin. The CO2 from the southern Jiangsu should be stored in the southern Subei basin and the offshore Southern South Yellow basin. When only the offshore storage blocks are optional CO2 sinks, the CO2 sources in the northern and central Jiangsu mainly match the sinks in the northwestern Southern South Yellow basin. The CO2 sources from southern Jiangsu mainly match the sinks in the southern and eastern Southern South Yellow basin. © 2018 Society of Chemical Industry and John Wiley & Sons, Ltd.

“…The onshore portion of the Sulu orogen is divided into two parts: the ultrahigh‐pressure and the high‐pressure metamorphic belts (Xu et al, ). The boundary of those two belts is believed to cross the SYS and extend eastward to the Korean Peninsula (Oh, ; Li et al, 2014a, b).…”

“…The evolution of the SYS region can be divided into four major stages (Li, ; Li et al, 2014a, b; Zhang et al, ): During the Proterozoic, the basement of the SCB was formed during the Jinning Movement (~800 Ma), when the SYS area was located in the northeastern portion of the Yangtze Block. From early Palaeozoic to Triassic, the SYS area experienced continuous marine carbonate sedimentation. This region experienced uplift and erosion during the Indosinian Movement (~205 Ma), when the SCB and the NCB collided along the Qinling‐Dabie–Sulu orogenic belt and the Tanlu Fault (Ames et al, ; Hou et al, ; Li et al, ; Li et al, ; Li et al, 2014a, b). At this time, the Tanlu Fault became a left‐lateral strike‐slip fault (Zhu et al, ). From the late Mesozoic to early Cenozoic, the SYS experienced extensional stress resulting in the generation of half‐grabens that were subsequently filled with terrestrial sediments.…”

“…At this time, the Tanlu Fault became a left‐lateral strike‐slip fault (Zhu et al, ). From the late Mesozoic to early Cenozoic, the SYS experienced extensional stress resulting in the generation of half‐grabens that were subsequently filled with terrestrial sediments. During the late part of the Yanshan Movement (~66 Ma), the SYS area experienced a strong magmatic event (Li et al, 2014a, b), and the Sulu ultrahigh‐pressure metamorphic belt was generated by the collision of the SCB and the NCB (Hong and Choi, ). After the Neogene, the SYS basin experienced subsidence and terrestrial sedimentation. During this time, there was a small amount of faulting and folding in the SYS, while the Tanlu Fault reversed motion direction and became a right‐lateral strike‐slip fault (Hou et al, ).…”

“…Different tectonic models of the collision between the NCB and the SCB have been proposed to explain the tectonic evolution of the region (Xu et al, ; Okay et al 1993; Yin and Nie, ; Zhang, ; Li and Yang, ; Zhang et al, ; Li et al, ). Some models suggest that eastern China is tectonically connected with the ultrahigh‐pressure belt in the Korea Peninsula (Kim et al, ; Oh, ; Jung et al, ; Li et al, 2014a, b). However, the connection of those tectonic blocks is still unclear due to the lack of detailed geologic and geophysical data in the SYS.…”

Upper crustal structure beneath the northern South Yellow Sea revealed by wide‐angle seismic tomography and joint interpretation of geophysical data

et al. 2016

Mapping the crustal structure beneath the South Yellow Sea (SYS), which includes the collision zone between the North China Block and the South China Block, will help to reveal the geologic history and relationship between these geologic blocks. Previous interpretations of the crustal structure of the SYS did not use detailed seismic velocity structure as a constraint. We produced an upper crustal velocity model of the northern SYS using a new wide‐angle seismic dataset. Velocity anomalies resolved by our models correlate well with known features such as sedimentary basins and the tectonic uplifts in the SYS as low‐ and high‐velocity anomalies, respectively. As might be expected, not only major faults and/or lithologic boundaries were found to be associated with large velocity gradients, but also our models exhibited resolvable deeply penetrating vertical low‐velocity anomalies associated with the locations of strike‐slip faults that were poorly resolved in an older seismic reflection profile. Our interpretations of the locations of major faults were based on the stacked seismic reflection profile and velocity modelling of wide‐angle seismic array data and were extended to neighbouring regions by following trends in gravity, magnetic and earthquake location data. Faults traversing the North Basin of the SYS converged with the onshore Jia‐Xiang Fault (JXF), suggesting that the branching of the JXF fault system controlled the formation of the North Basin. The distribution of the strike‐slip faults resolved by our modelling of the JXF leads us to propose a model for the North Basin as a strike‐slip stress regime that is consistent with the known tectonic framework. These models will be useful for future analysis of the regional tectonic evolution of the SYS region. Copyright © 2016 John Wiley & Sons, Ltd.

Coupling relationship between sedimentary basin and Moho morphology in the South Yellow Sea, East China

et al. 2020

The development of the sedimentary basin in the South Yellow Sea that lies between the Chinese mainland and the Korean Peninsula well documents the tectonic evolution of eastern China. However, the Moho morphology and its relationship with the basin in this area remain poorly understood. Here we used high‐resolution 2D seismic lines and well data to map the geometry, structure, and distribution of the sedimentary basin in the South Yellow Sea. Our results suggest that the South Yellow Sea Basin can be divided into two distinct depressions and three uplifts. The depressions consist of eight depositional sags that are largely controlled by ENE‐, EW‐, and WNW‐striking normal faults. The basin depth reaches 9,500 m in the depressions, but is only <2000 m in the uplift zones. Calculated using a gravity stripping method, the Moho depth varies between 27.4 and 31.5 km. The basin is isostatically compensated and the Moho morphology approximately mirrors that of the basin basement. The Moho lows correspond to the uplift zones and Moho highs correspond to the depression zones, with exception of a sag in the Northern Depression. This exception is caused by the presence of a geological body of high velocity and high density beneath the sag. This body is likely to represent high‐pressure metamorphic rock that initially formed during the collision between the Sino‐Korean and Yangtze cratons and are currently overlain by the sedimentary basin. Based on the stretching factors and strain rates of the South Yellow Sea Basin, we propose that development of the basin was primarily driven by the subduction and retreat of the Pacific Plate since the Late Cretaceous, combined by far‐field effects from the convergence between the Indian and Eurasian plates during the Cenozoic.
