Reliable chronology is crucial for reconstructing the sedimentary history and sea level fluctuations. However, lack of robust ages late Quaternary deposits on North Yellow Sea (NYS) shelf hampered our understanding its processes. In this study, quartz optically stimulated luminescence (OSL) feldspar post-infrared infrared (post-IR IRSL) dating protocol were utilized to establish a detailed chronostratigraphy upmost 30 m core DLC70-2 from central NYS. Based lithology features results, three...
The marginal sea and back-arc basins in the Western Pacific Ocean have become focus of tectonics due to their unique tectonic location. To understand deep crustal structure region, we present a 545-km-long active-source ocean bottom seismometer (OBS) wide-angle reflection/refraction profile East China Sea. P wave velocity model shows that Moho depth rises significantly, from approximately 30 km Sea shelf 16 axis Okinawa Trough. lower high-velocity zone (HVZ) southern Trough, with Vp 6.8–7.3...
Exploration for marine hydrocarbon has gained great attention in China recently.The Pre-Cenozoic strata were widely distributed the South Yellow Sea.In order to better understand these strata,we made comparison this article of and their depositional features between sea Sichuan basin upper Yangtze with well data from lithostratigraphic Upper area.It is concluded that Mesozoic Paleozoic two areas dominated by carbonate platform deposits are generally similar before Indosinian movement,but...
Based on the paleomagnetic data from Tibet and adjacent areas,and studies paleogeography,petrlogy,sedimentology tectonic deformation,we quantitatively reconstructed relative position motion of blocks in area.The Qiangtang block began to drift northwards rapidly Late Carboniferous,and collided with ancient Asian continent during Permian Early Triassic.The Gangdise separated Gondwana late Triassic,and Early-Late Cretaceous.The Himalayan Jurassic,and Cretaceous,and Cretaceous Tertiary.
The use of ocean bottom seismometer (OBS) is great significance to explore the tectonic evolution East China Sea. To study characteristics deep geological structure from Sea shelf basin Ryukyu trench uplifting fold belt, NW-SE active source seismic experiment (OBS-2015) was carried out in By using delayed fire multilayer gun array, wide-angle reflection and refraction signals up Moho can be obtained continental Okinawa Trough, various phases such as Ps, Pg PmP recognized. data acquisition...
The seismic safety evaluation of artificial reef islands is great significance for ensuring their long-term stable operation and the residents’ lives. However, due to an insufficient understanding coral reefs’ basic characteristics, current research on stability neglects influence pore water pressure abnormal layers formed during geological evolution. To further study impact earthquakes reefs in South China Sea, this paper takes Meiji Reef as object, establishes a 3-D model containing...
