| 1 | Adakitic rocks associated with the Shilu copper–molybdenum deposit in the Yangchun Basin,South China,and their tectonic implications显示文摘South China is famous for the extensive magmatism and polymetallic mineralization that took place there in the Mesozoic. Shilu is a large porphyry–skarn Cu–Mo deposit in the Yangchun Basin, South China. The lithology of the Shilu intrusion is granodiorite and quartz diorite, both of which are high-K calc-alkaline series, with high Sr([400 ppm) content along with low Y and Yb contents. Most of the samples have characteristics of adakite except for a few samples that have slightly higher Y and Yb contents, which may be plausibly explained by crustal contamination. Laser Ablation Inductively Coupled Plasma Mass Spectrometry zircon U–Pb dating revealed ages between 106.6 ± 1.3 and 103.9 ± 0.5 Ma, with multiple magmatic pulses. Molybdenite Re–Os isochron age of 102.2 ± 2.9 Ma(MSWD = 9.4) was determined, which is identical to the youngest zircon U–Pb age(103.9 ± 0.5 Ma) within error.The Shilu intrusion has high oxygen fugacity as indicated by high zircon Ce^(4+)/Ce^(3+) and Eu_N/Eu_N* ratios. Considering the geochemical characteristics(high Sr, and low Y and Yb contents), high oxygen fugacity, and copper mineralization of the Shilu intrusion, it was most likely formed by partial melting of a subducted young oceanic slab. Whole-rock Sr–Nd isotope-, zircon Hf isotope-, and whole-rock trace element analyses show that Shilu adakitic magmas may have interacted with type II enriched mantle and/or crustal materials during ascent. South China was affected by the Pacific tectonic regime to the east and the Neo-Tethys tectonic regime to the south in the Cretaceous. Based on the Pacific Plate drifting and rotation history, it is hard to explain how the Pacific Plate would have subducted and melted, forming adakitic rocks in the Shilu region. Considering the tectonic history of Southeast Asia and the South China Sea, the Neo-Tethys trench should have been much closer to the South China Block in the Cretaceous, and thus have had a greater impact on the South China Block. Based on the subduction direction, time of subduction,and distance between the Neo-Tethys subduction zone and the Shilu deposit, subduction of the Neo-Tethys ridge is the best mechanism for explaining the Shilu adakitic rocks and Cu–Mo mineralization. | Lipeng Zhang Yongbin Hu Jinlong Liang Trevor Ireland Youliang Chen Rongqing Zhang Saijun Sun Weidong Sun | 2017 | Acta Geochimica2017,36,2: | 15 |

| 3 | Plate convergence in the Indo-Pacific region显示文摘The Indo-Pacific convergence region is the best target to solve the teo remaining challenges of the plate tectonics theory,i.e.,subduction initiation and the driving force of plate tectonics.Recent studies proposed that the Izu-Bonin subduction initiation belongs to spontaneous initiation,which implies that it started from extension,followed by low angle subduction.Numerical geodynamic modeling suggests that the initiation of plate subduction likely occurred along a transform fault,which put the young spreading ridge in direct contact with old oceanic crust.This,however,does not explain the simultaneous subduction initiation in the west Pacific region in the Cenozoic.Namely,the subduction initiations in the Izu-BoninMariana,the Aleutian,and the Tonga-Kermadec trenches are associated with oceanic crusts of different ages,yet they occurred at roughly the same time,suggesting that they were all triggered by a maj or change in the Pacific plate.Moreover,low angle subduction induces compression rather than extension,which requires external compression forces.Given that the famous Hawaiian-Emperor bending occurred roughly at the same time with the onset of westward subductions in the west Pacific,we propose that these Cenozoic subductions were initiated by the steering of the Pacific plate,which are classified as induced initiation.Induced subduction initiation usually occurs in young ocean basins,forming single-track subduction.The closure s of Neo-Tethys Oceans were likely triggered by plume s in the south,forming northward subductions.Interestingly,the Indian plate kept on moving northward more than 50 Ma after the collision between the Indian and Eurasian continents and the break-off of the subducted oceanic slab attached to it.This strongly suggests that slab pull is not the main driving force of plate tectonics,whereas slab sliding is. | SUN Weidong ZHANG Lipeng LIAO Renqiang SUN Saijun LI Congying LIU He | 2020 | Journal of Oceanology and Limnology2020,38,4: | 4 |

| 5 | High oxygen fugacity magma:implication for the destruction of the North China Craton显示文摘The mechanism of lithospheric removal and destruction of the North China Craton(NCC)has been hotly debated for decades.It is now generally accepted that the subduction of the(Paleo)-Pacific plate played an important role in this process.However,how the plate subduction contributed to the craton destruction remains unclear.Here we report high oxygen fugacity(fO2)characteristics of the Yunmengshan granite,e.g.,hematitemagnetite intergrowth supported by zircon Ce^4+/Ce^3+ratios and apatite Mn oxygen fugacity indicator.High fO2 magmas are widely discovered in Late Mesozoic(160-130 Ma)adakitic rocks in central NCC.The origin of high fO2 magma is likely related to the input of the'oxidized mantle components',which shows a dose connection between plate subduction and destruction of the craton.The research area is^1500 km away from the current Pacific subduction zone.Considering the back-arc extension of Japan Sea since the Cretaceous,this distance may be shortened to^800 km,which is still too far for normal plate subduction.Ridge subduction is the best candidate that was responsible for the large scale magmatism and the destruction of the NCC.Massive slab-derived fluids and/or melts were liberated into an overlying mantle wedge and modified the lithospheric mantle.Rollback of the subducting plate induced the large-scale upwelling of asthenospheric mantle and triggered the formation of extensive high fO2 intraplate magmas. | Zhekun Zhang Mingxing Ling Lipeng Zhang Saijun Sun Weidong Sun | 2020 | Acta Geochimica2020,39,2: | 4 |

| 7 | The velocity structure of the Yinggehai Basin and its hydrocarbon implication显示文摘Two profiles of refraction and wide_angle reflection were completed in the Yinggehai Basin using ocean bottom hydrophones (OBHs) as receiver. These profiles reveal a low velocity layer (LVL) to the west of No. 1 Fault in the basin, with velocity of 3.0-3.5 km/s. Its upper interface lies at 3.5 km below the sea bottom at the NE end of the profiles, and deepens southwestward to 4 6 km near the axis of the basin. It coincides with the top of a gas_bearing, high_pressure layer defined by well logging. This suggests that the LVL is a layer of less_compacted and gas_charged sediments. The lower interface of the LVL is about 9 km in depth. Sediments above the LVL have velocity varying from 2 0 to 4 1 km/s. The acoustic basement is found only east of No. 1 Fault, with velocity of 5 8-6 2 km/s. A NNW_SSE_running OBH seismic profile across the Xisha Trough was completed on the same cruise. Moho and other deep interfaces are clearly visible in the profile. | Kanyuan Xia Di Zhou Daquan Su E.

| 8 | Enhance the delivery of light energy ultra-deep into turbid medium by controlling multiple scattering photons to travel in open channels显示文摘Multiple light scattering is considered as the major limitation for deep imaging and focusing in turbid media.In this paper,we present an innovative method to overcome this limitation and enhance the delivery of light energy ultradeep into turbid media with significant improvement in focusing.Our method is based on a wide-field reflection matrix optical coherence tomography(RM-OCT).The time-reversal decomposition of the RM is calibrated with the Tikhonov regularization parameter in order to get more accurate reversal results deep inside the scattering sample.We propose a concept named model energy matrix,which provides a direct mapping of light energy distribution inside the scattering sample.To the best of our knowledge,it is the first time that a method to measure and quantify the distribution of beam intensity inside a scattering sample is demonstrated.By employing the inversion of RM to find the matched wavefront and shaping with a phase-only spatial light modulator,we succeeded in both focusing a beam deep(~9.6 times of scattering mean free path,SMFP)inside the sample and increasing the delivery of light energy by an order of magnitude at an ultra-deep(~14.4 SMFP)position.This technique provides a powerful tool to understand the propagation of photon in a scattering medium and opens a new way to focus light inside biological tissues. | Jing Cao Qiang Yang Yusi Miao Yan Li Saijun Qiu Zhikai Zhu Pinghe Wang Zhongping Chen | 2022 | Light(Science & Applications)2022,11,5: | 2 |

| 13 | Abundance,Diversity and Functional Potentials of Planktonic Bacteria and Microeukaryotes in the Coral-Reef System of Xisha Islands,China显示文摘Corals influence microorganisms within the surrounding seawater,yet the diversities and functions of seawater bacteria and microeukaryotes in coral-reef systems have not been well addressed.We collected 40 seawater samples in outer coral reef flats and semi-closed inner lagoons from the surface,middle and bottom layers in the pristine coral-reef system of Xisha Islands,South China Sea.We detected the abundance,composition and distribution of bacteria and microeukaryotes using flow cytometry,qPCR and high throughput sequencing techniques,and profiled the potential ecological roles based on the information of 16S and 18S rDNA sequencing.In terms of flow cytometry,Prochlorococcus dominated the autotrophs with cell abundance ranging from 5.8×10^(2)to 5.44×10^(3)cells mL−1 seawater.Based on qPCR,the 16S rDNA copies were much higher in coral reef flats than in lagoons(P=0.003).The bacterial communities held significantly lower diversity in bottom waters compared with surface and middle waters(P<0.05),which were dominated by SAR11,Flavobacteriales,and Synechococcus.Alveolata represented most of the microeukaryotic communities with Dinophyceae and Syndiniales well represented in all samples.Neither bacterial nor microeukaryotic community exhibited distinct layer or niche pattern,however,Haptophyta and Picozoa decreased with depth and SAR 86,MAST-3 and Picozoa were enriched in lagoons(P<0.05).To adapt the nutrient-poor and organic matter-rich environment,bacterial nitrogen fixation and assimilatory/dissimilatory nitrate reduction were active in the system,and mixotrophy was the most important trophic strategy among microeukaryotes.The study highlighted the ecological adaptability of seawater microbes to the unique coral-reef environments. | ZHANG Xiaoli WANG Lei PENG Saijun WUZHONG Qiyue ZHANG Lei DONG Zhijun SUN Tingting LIU Ping ZHANG Qianqian ZHAO Jianmin | 2022 | Journal of Ocean University of China2022,21,3: | 1 |

| 16 | Commensal microbiota in the digestive tract:a review of its roles in carcinogenesis and radiotherapy显示文摘The human microflora is a complex ecosystem composed of diverse microorganisms mainly distributed in the epidermal and mucosal habitats of the entire body,including the mouth,lung,intestines,skin,and vagina.These microbial communities are involved in many essential functions,such as metabolism,immunity,host nutrition,and diseases.Recent studies have focused on the microbiota associated with cancers,particularly the oral and intestinal microbiota.Radiotherapy,the most effective cytotoxic modality available for solid tumors,contributes to the treatment of cancer patients.Mounting evidence supports that the microbiota plays pivotal roles in the efficacy and prognosis of tumor radiotherapy.Here,we review current research on the microbiota and cancer development,and describe knowledge gaps in the study of radiotherapy and the microbiota.Better understanding of the effects of the microbiome in tumorigenesis and radiotherapy will shed light on future novel prevention and treatment strategies based on modulating the microbiome in cancer patients. | Jiali Dong Yuan Li Huiwen Xiao Ming Cui Saijun Fan | 2022 | Cancer Biology & Medicine2022,19,1: | 1 |
