| 1 | The Sequence of Magmatic-Tectonic Events and Orogenic Processes of the Yanshan Belt, North China显示文摘This paper emphasizes that the interactive constraints of geology and isotopic dating is the best approach to construct the geological event sequence, and has compiled 106 data of reasonable isotopic ages for the igneous rocks of the Yanshan belt. We propose a sequence of mgmatic-tectonic events in the Jurassic-Cretaceous Yanshan orogen of North China. Five orogenic episodes are divided, (1) pre-and initial orogenic episode (Early Jurassic); (2) early orogenic episode (Middle Jurassic); (3) peak orogenic episode (Late Jurassic); (4) late orogenic episode (early Early Cretaceous),and (5) post-orogenic episode. Each episode is a short cycle, all of the orogenic processes construct a longer cycle, and they, in general, followed a counter-clockwise (ccw) PTt path. Finally, it is suggested that the Yanshanian movement was so intensive that the magmatism and tectonic deformation had involved all the lithosphere thickness and the lateAchaean-formed cratonic lithosphere had been significantly reworked. | DENG Jinfu, SU Shangguo, MO Xuanxue, ZHAO Guochun, XIAO Qinghiu, JI Guangyi,QIU Ruizhao, ZHAO Hailing, LUO Zhaohua, WANG Yang and LIU Cui China University of Geosciences, Beijing 100083 and Key Laboratory of Lithospheric Tectonics and Lithoprobe Techniques, Ministry of Education of China | 2004 | Acta Geologica Sinica(English Edition)2004，78，1： | 35 |
| 2 | Early Paleozoic ridge subduction in the Chinese Altai: Insight from the abrupt change in zircon Hf isotopic compositions显示文摘Zircons were separated from granitoids, gneisses, and sedimentary rocks of the Chinese Altai. Those with igneous characteristics yielded U-Pb ages of 280-2800 Ma, recording a long history of magmatic activity in the region. Zircon Hf isotopic compositions show an abrupt change at ~420 Ma, indicating that prior to that time the magmas came from both ancient and juvenile sources, whereas younger magmas were derived mainly from juvenile material. This may imply that the lithosphere was signifi- cantly modified in composition by a rapid addition of melt from the mantle. We suggest that this dramatic change was due to the onset of ridge subduction, which can account not only for the formation of voluminous granitoids, mafic rocks with complex compositions, and the association of adakite + high-Mg andesite + boninite + Nb-enriched basalt, but also for the coeval high-T, low-P metamorphism. | SUN Min LONG XiaoPing CAI KeDa JIANG YingDe WANG BuYun YUAN Chao ZHAO GuoChun XIAO WenJiao WU FuYuan | 2009 | Science China Earth Sciences2009，52，9： | 33 |
| 3 | EMP chemical ages of monazites from Central Zone of the eastern Kunlun Orogen:Records of multi-tectonometamorphic events显示文摘Two generations of monazite were identified in one mica schist sample from the central zone of the eastern Kunlun Orogen at the northern margin of the Qinghai-Tibet Plateau. The first generation was found in the cores of garnet porphyroblasts with relatively high Y2O3 contents (averaging 1.012±0.088 wt%). The second generation occurs either as inclusions in the rims of garnet porphyroblasts,matrix kyanite,plagioclase and quartz,or as separate crystals associated with matrix biotite and muscovite mostly having a relatively low Y2O3 content (averaging 0.479±0.100 wt%). Electron microprobe (EMP) Th-U-Pbtotal chemical dating for two grains of the first generation monazite yields average ages of 455 ± 18 Ma and 420 ± 20 Ma,respectively; six grains of the second generation gave an average age of 246.1 ± 3.8 Ma. These ages suggest that the core and rim of the garnet porphyroblasts and their associated assemblages record two events of significant tectonometamorphism. The formation of the Ordovician monazite is related to the tectonometamorphic event responsible for continuous amalgamation of the Gondwanaland in the Late Pan-African period or for consumption of the Proto-Tethys,whereas the development of the Triassic monazite is related to the tectonometamorphic event for consumption of the Paleo-Tethys. | CHEN NengSong SUN Min WANG QingYan ZHAO GuoChun CHEN Qiang SHU GuiMing | 2007 | Chinese Science Bulletin2007，52，16： | 28 |
| 4 | The Expression and Location of Midkine in Gastric Carcinomas of Chinese Patients显示文摘Midkine (MK), a heparin-binding growth factor, can regulate cell growth, survival and differentiation. MK is expressed at high levels in a variety of human carcinomas. Recently, the urine and serum MK concentration was analyzed in gastric cancer patient. However, the association of the cytokine mRNA expression with the categorical clinicopathological variables of the tumors and the location of its protein expression in the tumor tissues are still elusive. MK mRNA expression from the surgically resected specimens of healthy gastric tissues (9 cases), gastric cancer tissues and the matched non-cancerous tissues adjacent to the cancer (37 cases) were assessed by reverse transcriptase-polymerase chain reaction (RT-PCR) and real-time PCR. Immunohistochemical analysis was performed to locate MK in gastric cancer. The expression of MK mRNA in gastric cancer was much higher in tumor tissues than that in the non-cancerous tissues and control tissue samples. And its expression was significantly associated with the pTNM stage and distant metastasis, but not with the differentiation grade, tumor size and nodal involvement. MK protein was ubiquitous in the tumor, especially in the adenoid part of tumors. In addition, it was found in the cytoplasm of tumor cells and highly concentrated in nucleus and nucleolus. The expression level and location of MK in gastric tumor tissues of Chinese Patients may be related to the tumor genesis and progression. Further study is necessary on the mechanism of MK in gastric tumorigenesis and tumor growth. | Yaling Huang Guochun Cao Hui Wang Qingling Wang Yayi Hou | 2007 | Cellular & Molecular Immunology2007，4，2： | 17 |
| 5 | The discovery of the oldest rocks in the Kuluketage area and its geological implications显示文摘The basement rocks in the Kuluketage area are composed predominately of tonalite-trondhjemite-granodiorite rocks, and occured mainly in Xinger and Korla. U-Pb dating of TTG gneiss near Korla yielded a late Neoarchean weighted mean 207Pb/206Pb age of 2.65 Ga, which is the oldest published age for the TTG rocks in the Kuluketage area and thus suggests that Archean terrane in the area was formed in the late Neoarchean. The Korla gneiss is much younger than the TTG rocks in the northern Altyn Tagh, eastern Tarim Craton, indicating that the oldest terrane of the Tarim Craton was exposed probably in the northern Altyn Tagh. Until late Neoarchean, the Tarim continent extends to the Kuluketage area and finally had generated a relatively large uniform Archean basement within the craton. Zircon Hf isotopic analyses of the TTG gneiss give low εHf(t) values (-5 to 1) with Paleoarchean to Mesoarchean two-stage model ages (TDM2) between 3.0 and 3.3 Ga, suggesting that the basement rocks in the northern Tarim Craton were derived dominately from partial melting of Paleoarchean to Mesoarchean juvenile crustal material. The Hf model ages, therefore, indicate that no continent crust older than 3.3 Ga existed in the Kuluketage area. | LONG XiaoPing YUAN Chao SUN Min XIAO WenJiao ZHAO GuoChun ZHOU KeFa WANG YuJing HU AiQin | 2011 | Science China Earth Sciences2011，54，3： | 16 |

| 8 | Metamorphism of the northern Liaoning Complex:Implications for the tectonic evolution of Neoarchean basement of the Eastern Block,North China Craton显示文摘As one of the areas where typical late Archean crust is exposed in the Eastern Block of the North China Craton,the northern Laioning Complex consists principally of tonalitic-trondhjemitic-granodioritic(TTG) gneisses,massive granitoids and supracrustal rocks.The supracrustal rocks,named the Qingyuan Group, consist of interbedded amphibolite,hornblende granulite,biotite granulite and B1F.Petrological evidence indicates that the amphibolites experienced the early prograde(M1),peak(M2) and post-peak(M3) metamorphism.The early prograde assemblage(M1) is preserved as mineral inclusions,represented by actinotite + hornblende + plagioclase + epidote + quartz + sphene,within garnet porphyroblasts.The peak assemblage(M2) is indicated by garnet + clinopyroxene + hornblende + plagioclase + quartz + ilmenite, which occur as major mineral phases in the rock.The post-peak assemblage(M3) is characterized by the garnet + quartz symplectite.The P—T pseudosections in the NCFMASHTO system constructed by using THERMOCALC define the P-T conditions of Ml,M2 and M3 at 490-550℃/<4.5 kbar,780-810℃/7.65- 8.40 kbar and 630-670℃/8.15-9.40 kbar,respectively.As a result,an anticlockwise P-T path involving isobaric cooling is inferred for the metamorphic evolution of the amphibolites.Such a P-T path suggests that the late Archean metamorphism of the northern Liaoning Complex was related to the intrusion and underplating of mantle-derived magmas.The underplating of voluminous mantle-derived magmas leading to metamorphism with an anticlockwise P-T path involving isobaric cooling may have occurred in continental magmatic arc regions,above hot spots driven by mantle plumes,or in continental rift environments. A mantle plume model is favored because this model can reasonably interpret many other geological features of late Archean basement rocks from the northern Liaoning Complex in the Eastern Block of the North China Craton as well as their anticlockwise P—T paths involving isobaric cooling. | Kam Kuen Wu Guochun Zhao Min Sun Changqing Yin Yanhong He Pui Yuk Tam | 2013 | Geoscience Frontiers2013，4，3： | 14 |

| 16 | Ages and Hf isotopes of detrital zircons from the Permian strata in the engbatu area(Inner Mongolia) and tectonic implications显示文摘The Central Asian Orogenic Belt(CAOB) was built up through protracted accretion and collision of a variety of terranes/micro-continents during Neoproterozoice Mesozoic time. To understand potential links among Paleozoic subduction and accretionary processes that were operative during the development of the southeastern CAOB, we conducted a combined U-Pb and Hf-isotope analysis of detrital zircons from previously defined Devonian, Carboniferous and Early Permian strata in the Bengbatu area,Inner Mongolia. Detrital zircons from(meta-) sandstones in these strata commonly yield major Paleozoic age populations at ca. 300-261 Ma, 351-300 Ma and 517-419 Ma, and also give several Precambrian ages that range from 2687 Ma to 544 Ma. The youngest ages redefine the deposition of all these strata to be in the Middle Permian(Wordiane Capitanian) or later, much younger than previously considered.These ages, coupled with regional magmatic records, support an interpretation of most surrounding areas as possible detritus sources, including the Mongolian arcs to the north, the Northern Accretionary Orogen to the south, and the intervening Erenhote Hegenshan Ophiolite Belt. Zircons with magmatic ages of ca. 500-350 Ma and ca. 300-261 Ma display a large range of εHf(t) values(-13.97 to +15.31),whereas ca. 350-300 Ma zircons are dominated by positive εHf(t) values(+0.14 to +16.00). These results support the occurrence of two significant shifts of the zircon εHf(t) values, which has tectonic implications for the understanding of the Carboniferouse Permian evolution of the southeastern CAOB. A marked shift from mixed to positive zircon εHf(t) values at 350 -330 Ma likely manifests the incipient opening of the Hegenshan Ocean, due to the slab rollback of the subducting Paleo-Asian Oceanic lithosphere. Another shift from positive to mixed zircon εHf(t) values at ca. 300 Ma likely corresponds to a tectonic switch from syn-orogenic subduction-related to post-orogenic extensional setting, genetically related to the tectonic collapse of a formerly overthickened crust. | Bing Xu Guochun Zhao Jianhua Li Dongxing Liu Bo Wang Yigui Han Paul R.

| 17 | Case study on stratospheric and mesospheric concentric gravity waves generated by deep convection显示文摘Concentric gravity waves(CGWs)in the middle and upper atmosphere show wave-coupling processes between the lower atmosphere and the middle and upper atmosphere.In this research,we analyzed a case of CGWs detected simultaneously by the AIRS(Atmospheric Infrared Sounder)and the VIIRS/DNB(Day/Night Band of the Visible Infrared Imager Radiometer Suite)in the stratosphere and mesosphere.Results showed that gravity waves(GWs)were generated by the collocated Hurricane Bejisa on the island of Mauritius.The AIRS data showed arc-like phase fronts of GWs with horizontal wavelengths of 190 and 150 km at 21:08 coordinated universal time(UTC)on 1 January 2014 and at 10:00 UTC on 2 January 2014,whereas the DNB observed arced GWs with horizontal wavelengths of 60 and 150 km in the same geographic regions at 22:24 UTC.The characteristics of CGW parameters in the stratosphere(~40 km)and the mesosphere(~87 km),such as the vertical wavelength,intrinsic frequency,and intrinsic horizontal phase speed,were first derived together with the background winds from ERA5 reanalysis data and Horizontal Wind Model data through the dispersion relationship of GWs and the wind-filtering theory. | GuoChun Shi Xiong Hu ZhiGang Yao WenJie Guo MingChen Sun XiaoYan Gong | 2021 | Earth and Planetary Physics2021，5，1： | 2 |
| 18 | Oblique derivative problem for general Chaplygin-Rassias equations显示文摘The present paper deals with the oblique derivative problem for general second order equations of mixed (elliptic-hyperbolic) type with the nonsmooth parabolic degenerate line K1(y)uxx+|K2(x)|uyy+a(x,y)ux+b(x, y)uy+c(x,y)u=-d(x,y) in any plane domain D with the boundary D=Γ∪L1∪L2∪L3∪L4, whereΓ(■{y>0})∈Cμ2 (0<μ<1) is a curve with the end points z=-1,1. L1, L2, L3, L4 are four characteristics with the slopes -H2(x)/H1(y), H2(x)/H1(y),-H2(x)/H1(y), H2(x)/H1(y)(H1(y)=|k1(y)|1/2, H2(x)=|K2(x)|1/2 in {y<0}) passing through the points z=x+iy=-1,0,0,1 respectively. And the boundary condition possesses the form 1/2 u/v=1/H(x,y)Re[λuz]=r(z), z∈Γ∪L1∪L4, Im[λ(z)uz]|z=zl=bl, l=1,2, u(-1)=b0, u(1)=b3, in which z1, z2 are the intersection points of L1, L2, L3, L4 respectively. The above equations can be called the general Chaplygin-Rassias equations, which include the Chaplygin-Rassias equations K1(y)(M2(x)ux)x+M1(x)(K2(y)uy)y+r(x,y)u=f(x,y), in D as their special case. The above boundary value problem includes the Tricomi problem of the Chaplygin equation: K(y)uxx+uyy=0 with the boundary condition u(z)=φ(z) onΓ∪L1∪L4 as a special case. Firstly some estimates and the existence of solutions of the corresponding boundary value problems for the degenerate elliptic and hyperbolic equations of second order are discussed. Secondly, the solvability of the Tricomi problem, the oblique derivative problem and Frankl problem for the general Chaplygin- Rassias equations are proved. The used method in this paper is different from those in other papers, because the new notations W(z)=W(x+iy)=uz=[H1(y)ux-iH2(x)uy]/2 in the elliptic domain and W(z)=W(x+jy)=uz=[H1(y)ux-jH2(x)uy]/2 in the hyperbolic domain are introduced for the first time, such that the second order equations of mixed type can be reduced to the mixed complex equations of first order with singular coefficients. And thirdly, the advantage of complex analytic method is used, otherwise the complex analytic method cannot be applied. | WEN GuoChun LMAM, School of Mathematical Sciences, Peking University, Beijing 100871, China | 2008 | Science China Mathematics2008，51，1： | 2 |

| 20 | Review on the recent development of Li_(3)VO_(4)as anode materials for lithium-ion batteries显示文摘Among the various anodes,Li_(3)VO_(4)is a potential intercalation kind anode used in lithium-ion batteries(LIBs)that exhibits safer discharge voltage and higher capacity than graphite,a lower voltage plateau than Li_(4)Ti_(5)O_(12),and smaller volume difference in the Li^(+)intercalation/deintercalation process than metals and alloys.However,the comparatively low electronic conductivity,low initial coulombic efficiency(ICE)and serious capacity decay make the Li_(3)VO_(4)anode unviable when it comes to practical implementation.Therefore,this paper reviews the research progress of Li_(3)VO_(4)in recent years,mainly including the strategies of developing different synthesis methods to construct unique morphology,through coating,compositing or elemental doping to increase the ICE,electronic conductivity and the cycle constancy.Moreover,the application of Li_(3)VO_(4)anode materials in other energy storage systems is summarized.Lastly,the development prospect and challenge of Li_(3)VO_(4)anodes are discussed. | Limin Zhu Zhen Li Guochun Ding Lingling Xie Yongxia Miao Xiaoyu Cao | 2021 | Journal of Materials Science & Technology2021，，30： | 2 |
