| 1 | Stretching characteristics and its dynamic significance of the northern continental margin of South China Sea显示文摘To investigate the thinning of the whole crust, and the contribution of the upper versus lower crust to the stretching since Cenozoic, we calculated the stretching factor of the northern margin of South China Sea with data such as whole crustal thickness, depth of Cenozoic sedimentary basement and the horizontal displacement of faults. An isometric line drawing on whole crustal stretching factor is then obtained. Along the seismic Line 1530 in Baiyun sag, we also calculated the stretching factors of the upper and lower crust. The results suggest that the whole crustal thickness decreases seaward while the whole crustal stretching factor increases from shelf to slope. The Moho upwells highest beneath where the crust is thinned most. The value of the whole crustal stretching factor ranges from 1.5 to 6. Two areas were thinned intensely: the center of Yinggehai Basin, and the Baiyun sag in the Pearl River Mouth Basin. The calculation of the upper and lower crustal stretching factors from DSP1530 in Baiyun sag shows that the original crust of Baiyun sag should be thinned before deformation. Its pre-Cenozoic evolution as well as tectonic position during Cenozoic might be responsible for that. | ZHANG YunFan SUN Zhen ZHOU Di GUO XingWei SHI XiaoBin WU XiangJie PANG Xiong | 2008 | Science China Earth Sciences2008，51，3： | 15 |
| 2 | Characteristics of Meso-Cenozoic Igneous Complexes in the South Yellow Sea Basin,Lower Yangtze Craton of Eastern China and the Tectonic Setting显示文摘The South Yellow Sea Basin is partially surrounded by the East Asian continental MesoCenozoic widespread igneous rocks belt.Magnetic anomaly and multi-channel seismic data both reveal the prevalent occurrence of igneous rocks.We preliminarily defined the coupling relation between magnetic anomalies and igneous rock bodies.Some igneous complexes were also recognized by using multi-channel seismic and drilling data.We identified various intrusive and extrusive igneous rock bodies,such as stocks,sills,dikes,laccoliths and volcanic edifice relics through seismic facies analysis.We also forecasted the distribution characteristics of igneous complexes.More than fifty hypabyssal intrusions and volcanic relics were delineated based on the interpretation of magnetic anomaly and dense intersecting multi-channel seismic data.It is an important supplement to regional geology and basin evolution research.Spatial matching relations between igneous rock belts and fractures document that extensional N-E and N-NE-trending deep fractures may be effective pathways for magma intrusion.These fractures formed under the influence of regional extension during the MesoCenozoic after the Indosinian movement.Isotopic ages and crosscutting relations between igneous rock bodies and the surrounding bedded sedimentary strata both indicate that igneous activities might have initiated during the Late Jurassic,peaked in the Early Cretaceous,gradually weakened in the Late Cretaceous,and continued until the Miocene.Combined with previous studies,it is considered that the Meso-Cenozoic igneous activities,especially the intensive igneous activity of the Early Cretaceous,are closely associated with the subduction of the Paleo-Pacific Plate. | PANG Yumao ZHANG Xunhua XIAO Guolin GUO Xingwei WEN Zhenhe WU Zhiqiang ZHU Xiaoqing | 2017 | Acta Geologica Sinica(English Edition)2017，91，3： | 15 |
| 3 | Basin modeling in the initial stage of exploration: a case study from the North Subbasin of the South Yellow Sea Basin显示文摘Basin modeling has become an important tool for analyzing sedimentary basins. The North Subbasin of the South Yellow Sea Basin is filled with thick Meso-Cenozoic terrigenous deposits during the rift evolution stage. The accumulation of data and achievements of geological investigations in recent years have provided the preconditions for basin modeling. The necessary parameters and geological elements for simulations are collated and summarized. Modeling of tectono-thermal evolution is performed and the related trend in heat flow is reconstructed and calibrated. The heat flow value commences from an average level of 61 m W/m^2 during MiddleLate Jurassic, rises to about 80 m W/m^2 from circa 145 Ma to circa 74 Ma, and then undergoes a gradual decline to65 m W/m^2 until the end of Oligocene.Three evolutionary phases, namely, the initial rifting phase, syn-rifting phase, and post-rifting phase, have been identified. The modeling results show that the North Subbasin generally enters into a stage of strong rifting during Cretaceous and undergoes rapid subsidence until the Late Cretaceous,then follows by a stage of moderate rifting during the Paleogene. The input and general workflow involved in 3-D modeling are introduced. Reconstruction of the petroleum system in the North Subbasin reveals that the threshold depth of hydrocarbon generation is located near the top of the Paleogene Funing formation, and the underlying Jurassic and Cretaceous source rocks have reached or exceeded peak oil generation and have almost completed the generation and expulsion of hydrocarbons. The main generation and expulsion in the Jurassic source rocks take place during the syn-rifting and post-rifting phases, whereas the peak generation and expulsion in the Cretaceous and Paleogene source rocks take place during the post-rifting phase. Although the study area is still a relatively less explored sedimentary basin, the results of modeling can provide valuable information for exploration. A preliminary discussion of the main uncertainty factors is also presented. | PANG Yumao ZHANG Xunhua GUO Xingwei XIAO Guolin HAN Zuozhen | 2017 | Acta Oceanologica Sinica2017，36，9： | 10 |
| 4 | New insights into marine hydrocarbon geological conditions in the South Yellow Sea Basin:evidence from borehole CSDP-2显示文摘The South Yellow Sea Basin(SYSB) has multiple sets of proven source rocks and good hydrocarbon prospects,but no industrial oil and gas has been explored at present.To solve this puzzle for petroleum geologists,we systematically investigated the marine hydrocarbon geological conditions based on cores and testing data from borehole CSDP-2,the first exploration well with continuous coring in SYSB.The qualities of source rocks are evaluated in detail according to organic matter abundance,type,and maturity.The reservoir characterization mainly includes porosity,permeability,and reservoir space.Displacement pressure test and stratum thickness are the main foundations for defining the caprocks.Then,the oil-source rock correlation in the Permian and stratum model are analyzed to determine the favorable source-reservoir-caprock assemblages.The results show that three sets of effective source rocks(the Lower Triassic,Upper Permian,and Lower Permian),two sets of tight sandstone re servoirs(the Upper Permian and Lower Silurian-Upper Devonian),and two sets of caprocks(the Lower Triassic and Carboniferous) combine to constitute the hydrocarbon reservoir-forming as se mblages of 'lower-ge neration and upper-accumlation' and 'self-generation and self-accumlation',thus laying a solid foundation for promising petroleum prospects.The three sets of marine source rocks are characterized by successive generation and expulsion stages,which guarantees multistage hydrocarbon accumulation.Another three sets of continental source rocks distributed across the Middle Jurassic,Upper Cretaceous,and Paleogene depression areas,especially in the Northern Depression,may supplement some hydrocarbons for the Central Uplift through faults and the Indosinian unconformity.The favorable Permian exploration strata have been identified in the Central Uplift of SYSB.First,the Lower Permian and Upper Permian source rocks with high organic matter abundance and high thermal maturity supply sufficient hydrocarbons.Secondly,the interbedding relationship between the source rocks and sandstones in the Upper Permian strata ensures that hydrocarbons have been migrated into the nearby Upper Permian sandstones,reflecting near-source hydrocarbon accumulation.Finally,the good sealing property of the Lower Triassic Qinglong Formation caprocks plays an indispensable role in hydrocarbon preservation of the Permian reservoirs.This conclusion is supported by direct oil shows,gas logging anomalous layers,and hydrocarbon-bearing fluid inclusions. | CAI Laixing XIAO Guolin ZENG Zhigang ZHANG Xunhua GUO Xingwei WANG Shuping | 2020 | Journal of Oceanology and Limnology2020，38，4： | 3 |
| 5 | Provenance and Tectonic Implications of Paleozoic Strata in the South Yellow Sea Basin, China-Revealed from the Borehole CSDP-2显示文摘Well CSDP-2 is a fully coring deep drilling hole, penetrating the thick Paleozoic marine strata in the South Yellow Sea Basin(SYSB) in the lower Yangtze Block(LYB). Based on the petrological and geochemical analysis of 40 sandstone samples from the core CSDP-2, the provenance and tectonic features of Paleozoic detrital rocks from SYSB are analyzed and systematically delineated in this article. The results show that the Silurian – Carboniferous sandstones are mature sublitharenite, while the Permian sandstones are unstable feldspathic litharenite. The average CIA(chemical index of alteration) is 74.61, which reflects these sediments were derived from source rocks with moderate chemical weathering. The REE(rare earth element) patterns are characterized by LREE enrichment, flat HREE and obviously negative Eu anomaly, which are similar to that of the upper continental crust. Dickinson QFL discrimination results indicate the recycled orogeny provenance. Various diagrams for the discrimination of sedimentary provenance based on major and trace element data show all the sediments were derived predominantly from quartz sedimentary rocks, of which the Permian strata contain more felsic sedimentary rocks. Geochemical data for these detrital rocks suggest they occur at the passive continental margin and island arc settings, and the Permian sandstone presents active continental margin setting. | GAO Xiaohui ZHANG Xunhua GUO Xingwei CAI Laixing HOU Fanghui ZHU Xiaoqing | 2020 | Journal of Ocean University of China2020，19，3： | 2 |

| 8 | Entropy-Based Global and Local Weight Adaptive Image Segmentation Models显示文摘This paper proposes a parameter adaptive hybrid model for image segmentation. The hybrid model combines the global and local information in an image, and provides an automated solution for adjusting the selection of the two weight parameters. Firstly, it combines an improved local model with the global Chan-Vese(CV) model, while the image’s local entropy is used to establish the index for measuring the image’s gray-level information. Parameter adjustment is then performed by the real-time acquisition of the ratio of the different functional energy in a self-adapting model responsive to gray-scale distribution in the image segmentation process.Compared with the traditional linear adjustment model, which is based on trial-and-error, this paper presents a more quantitative and intelligent method for achieving the dynamic nonlinear adjustment of global and local terms.Experiments show that the proposed model achieves fast and accurate segmentation for different types of noisy and non-uniform grayscale images and noise images. Moreover, the method demonstrates high stability and is insensitive to the position of the initial contour. | Gang Li Yi Zhao Ling Zhang Xingwei Wang Yueqin Zhang Fayun Guo | 2020 | Tsinghua Science and Technology2020，25，1： | 1 |

| 15 | Geochemistry of the upper Permian sandstones in the Dalong Formation in the South Yellow Sea Basin,East China:implications to provenance,weathering,and tectonic setting显示文摘To reconstruct the paleoenvironment,the petrography and geochemical compositions of the upper Permian Dalong Formation(Fm)(P_(3)d)sandstones in the Central Uplift,South Yellow Sea Basin,was investigated,after which the provenance,tectonic setting,weathering conditions,and diagenetic history were determined.The Dalong Fm is mainly composed of sandstones with a few mudstones and limestones.The petrographic analysis showed that the P_(3)d sandstones are in low maturity and could be classified into feldspar sandstone and lithic sandstone on average framework composition of Q_(63)F_(16)L_(21).The major and trace element results show that Dalong Fm sandstones are enriched in Rb and depleted in Cr and Ni compared with the upper continental crust(UCC).The chemical weathering intensity is weak to low moderate in the source area as indicated by the chemical index of alteration(CIA)and other results from a variety of methods.The diagenetic process included three main stages:eodiagenesis,mesodiagenesis,and telodiagenesis.Tectonic discrimination plots show that the source areas were an active continental margin(ACM)and a passive continental margin(PCM),which may have been related to the northward movement of the Lower Yangtze Plate(LYP)and the collision between the LYP and the North China Plate(NCP). | Yuxiao HUANG Xingwei GUO Xunhua ZHANG Laixing CAI | 2021 | Journal of Oceanology and Limnology2021，39，3： | 0 |

| 18 | Proteomic analysis of down-regulated proteins in colonic mucosa of chronic slow transit constipation rats显示文摘Objective:To investigate the alternations of proteins in the colonic mucosa of chronic slow transit constipation(STC) rats with a 2-DE-based proteomic method and analyze the function of these down-regulated proteins so as to provide theoretical basis for the pathogenesis of intestinal mucosa of chronic STC rats.Methods:STC model was established by feeding rats with 8 mg/(kg·d) diphenoxylate for 120 d.An experimental model of chronic STC rat was used for separation of proteomics from colonic mucosa using two-dimensional electrophoresis(2-DE).Proteins altered in expressional level were identified by Image Master 2DElite,mass spectrometry,and bibliometrics were applied to identify the differential protein expression and their clinical significance and function were analyzed.Results:Obvious differential protein expression was observed in the pathogenesis of STC,including mast cell protease(A1),non-specific dipeptidase(A2) and chondrosome succinate dehydrogenase precursor(A3).The expressions of A1,A2 and A3 were down-regulated in the gel graph of STC rats.Conclusion:The down-regulation of chondrosome succinate dehydrogenase,mast cell protease as well as non-specific dipeptidase in rat colon suggests the functional impairment of the oxidoreduction of mitochondrion is very important in the genesis and development of STC.The immunological reaction of STC rats is weakened,and the function of digesting and absorbing protein may be damaged to some extent. | Wang Xingwei Liu Haifeng Xu Mei Chen Gang He Juntang Wang Guo' an TengXiaochun Fang Dianchun | 2009 | Journal of Medical Colleges of PLA(China)2009，24，3： | 0 |
| 19 | Characteristics of crustal variation and extensional break-up in the Western Pacific back-arc region based on a wide-angle seismic profile显示文摘The marginal sea and back-arc basins in the Western Pacific Ocean have become the focus of tectonics due to their unique tectonic location.To understand the deep crustal structure in the back-arc region,we present a 545-kmlong active-source ocean bottom seismometer(OBS)wide-angle reflection/refraction profile in the East China Sea.The P wave velocity model shows that the Moho depth rises significantly,from approximately 30 km in the East China Sea shelf to approximately 16 km in the axis of the Okinawa Trough.The lower crustal high-velocity zone(HVZ)in the southern Okinawa Trough,with V_(p) of 6.8-7.3 km/s,is a remarkable manifestation of the mantle material upwelling and accretion to the lower crust.This confirms that the lower crustal high-velocity mantle accretion is developed in the southern Okinawa Trough.During the process of back-arc extension,the crustal structure of the southern Okinawa Trough is completely invaded and penetrated by the upper mantle material in the axis region.In some areas of the southern central graben,the crust may has broken up and entered the initial stage of seafloor spreading.The discontinuous HVZs in the lower crust in the back-arc region also indicate the migration of spreading centers in the back-arc region since the Cenozoic.The asthenosphere material upwelling in the continent-ocean transition zone is constantly driving the lithosphere eastward for episodic extension,and is causing evident tectonic migration in the Western Pacific back-arc region. | Jianghao Qi Xunhua Zhang Zhiqiang Wu XiangjunMeng Luning Shang Yang Li Xingwei Guo Fanghui Hou Enyuan He QiangWang | 2021 | Geoscience Frontiers2021，12，3： | 0 |
