| 1 | Destruction of the North China Craton显示文摘A National Science Foundation of China(NSFC) major research project,Destruction of the North China Craton(NCC),has been carried out in the past few years by Chinese scientists through an in-depth and systematic observations,experiments and theoretical analyses,with an emphasis on the spatio-temporal distribution of the NCC destruction,the structure of deep earth and shallow geological records of the craton evolution,the mechanism and dynamics of the craton destruction.From this work the following conclusions can be drawn:(1) Significant spatial heterogeneity exists in the NCC lithospheric thickness and crustal structure,which constrains the scope of the NCC destruction.(2) The nature of the Paleozoic,Mesozoic and Cenozoic sub-continental lithospheric mantle(CLM) underneath the NCC is characterized in detail.In terms of water content,the late Mesozoic CLM was rich in water,but Cenozoic CLM was highly water deficient.(3) The correlation between magmatism and surface geological response confirms that the geological and tectonic evolution is governed by cratonic destruction processes.(4) Pacific subduction is the main dynamic factor that triggered the destruction of the NCC,which highlights the role of cratonic destruction in plate tectonics. | ZHU RiXiang XU YiGang ZHU Guang ZHANG HongFu XIA QunKe ZHENG TianYu | 2012 | Science China Earth Sciences2012，55，10： | 119 |
| 2 | In-situ trace element analyses of zircons from Dabieshan Huangzhen eclogite:Trace element characteristics of eclogite-facies metamorphic zircon显示文摘The internal structures of zircons in eclogite from Huangzhen have been studied by cathodoluminescence (CL) microscopy. Two growth stages were distinguished: protolith magmatic cores and metamorphic overgrowth rims. These different domains were analyzed for trace elements using LAM-ICP-MS. The protolith and the overgrowth zircons have different trace elements characteristics. The trace element contents of protolith zircons are high and very variable. The overgrowth zircons show a typical trace element feature of equilibrium with garnet, e.g. low contents of HREE (132.2-197.6μg/g) and small differential degree of HREE ((Yb/Gd)cN=8.6-11.9). The contents of Nb, Ta and the ratio of Nb/Ta are lower in the metamorphic domains (0.5-1.4μg/g, 0.7-1.5μg/g, 0.3-1.3, respectively) than in the protolith domains (3.8-19.7μg/g, 2.7-12.1μg/g, 1.0-4.6, respectively). This is the first time to give the evidence that the metamorphic zircon equilibrates with the rutile, which formed during the peak metamorphic stage. | WU Yuanbao CHEN Daogong XIA Qunke TU Xianglin CHENG Hao | 2002 | Chinese Science Bulletin2002，47，16： | 26 |
| 3 | Deep carbon cycles constrained by a large-scale mantle Mg isotope anomaly in eastern China显示文摘Although deep carbon recycling plays an important role in the atmospheric CO_2 budget and climate changes through geological time,the precise mechanisms remain poorly understood.Since recycled sedimentary carbonate through plate subduction is the main light-δ^(26)Mg reservoir within deep-Earth,Mg isotope variation in mantle-derived melts provides a novel perspective when investigating deep carbon cycling.Here,we show that the Late Cretaceous and Cenozoic continental basalts from 13 regions covering the whole of eastern China have low δ^(26)Mg isotopic compositions,while the Early Cretaceous basalts from the same area and the island arc basalts from circum-Paciic subduction zones have mantle-like or heavy Mg isotopic characteristics.hus,a large-scale mantle low δ^(26)Mg anomaly in eastern China has been delineated,suggesting the contribution of sedimentary carbonates recycled into the upper mantle,but limited into the lower mantle.his large-scale spatial and temporal variation of Mg isotopes in the mantle places severe constraints on deep carbon recycling via oceanic subduction. | Shu-Guang Li Wei Yang Shah Ke Xunan Meng Hengci Tian Lijuan Xu Yongsheng He Jian Huang Xuan-Ce Wang Qunke Xia Weidong Sun Xiaoyong Yang Zhong-Yuan Ren Haiquan Wei Yongsheng Liu Fancong Meng Jun Yan | 2017 | National Science Review2017，4，1： | 23 |
| 4 | Water content in the early Cretaceous lithospheric mantle beneath the south-central Taihang Mountains: implications for the destruction of the North China Craton显示文摘Based on studies of the water content of the early Cretaceous Feixian high-magnesium basalts in the eastern part of the North China Craton(NCC),it has been suggested that the early Cretaceous lithospheric mantle of the eastern NCC was highly hydrous([1,000 ppm,H2O wt.)and that this high water content had significantly reduced the viscosity of the lithospheric mantle and provided a prerequisite for the destruction of the NCC.The eastern part of the NCC had undergone multistage subduction of oceanic plates from the south,north,and east sides since the early Paleozoic,and these events may have caused the strong hydration of the NCC lithospheric mantle.To determine which subduction had contributed most to this hydration,we measured the water contents of the peridotite xenoliths hosted by the early Cretaceous high-magnesium diorites of Fushan in the southcentral part of the Taihang Mountains.Our results demonstrate that the water content of the early Cretaceous lithospheric mantle beneath the south part of the Taihang Mountains was*40 ppm and significantly lower than that of the contemporary lithospheric mantle beneath the eastern part of the NCC.Thus,the hydration of the early Cretaceous lithospheric mantle of the eastern part of the NCC can be ascribed to the subduction of the Pacific plate from the west side.Thus,the main dynamic factor in the destruction of the NCC was likely the subduction of the Pacific plate. | Shaochen Liu Qunke Xia | 2014 | Chinese Science Bulletin2014，59，13： | 7 |
| 5 | Oxygen isotopic compositions of zircons from pyroxenite of Daoshichong, Dabieshan: Implications for crust-mantle interaction显示文摘Oxygen isotopic compositions of zircons from pyroxenite (-145 Ma) of Daoshichong, Dabieshan have been measured by an ion microprobe. Both within the single grain and among different grains, oxygen isotopic ratios are homogeneous, σ18O = (7.66‰±0.46)‰(1 SD, 1σ=0.10, n = 22). High σ18O values indicate that the mantle-derived parent magma of Daoshichong pyroxenite have undergone interaction with crustal materials. Combing with other geo-chemical constraints, the way of crust-mantle interaction is suggested to be source mixing other than crustal contamination. The time interval between crust-mantle interaction and formation of the parent magma of Daoshichong pyroxenite is less than several million years. The crustal component involving in crust-mantle interaction is mafic lower crust, and the parent magma of pyroxenite possibly contain large proportion (>37%) of such lower crust. | XIA Qunke E.Deloule WU Yuanbao CHEN Daogong CHENG Hao | 2002 | Chinese Science Bulletin2002，47，17： | 6 |
| 6 | Structural OH in mantle-derived clinopyroxene megacrysts from Nushan显示文摘Thirteen clinopyroxene megacrysts from Nushan Cenozoic basalts have been investigated by Fourier transform infrared spectrometer(FTIR). The results demonstrate that all samples contain trace amount of structural OH. Clinopyroxenes from Nushan show four groups of absorption bands, in which, 3 472-3 506 cm -1 is the major characteristic one. It is suggested that the position of major band is probably related to Al content: the position of major characteristic band for high_Al samples is around 3 470 cm -1 , whereas that for low_Al samples around 3 620 cm -1 . | Qunke Xia Daogong Chen Lihe Guo | 1998 | Chinese Science Bulletin1998，43，20： | 6 |
| 7 | Zircon SIMS ages and chemical compositions from Northern Dabie Terrain:Its implication for pyroxenite genesis显示文摘We present the results of a detailed micro-scale investigation of zircons from pyroxenites, Daoshicong Northern Dabie using a combination of SIMS and ICPMS. The SIMS measurements gave ages of 134-159 Ma. Its average of (144.516.2) Ma is interpreted as the best estimate of the pyroxenite intrusion. The crystallization of zircons continued for quite a long time and underwent slow cooling. The pyroxenites are products of post-collision magmatism. The REE pattern is HREE-enriched, and its HREE concentrations fall between the magmatic and metamorphic range of gneissic zircons from the Dabie area, which indicate the involvement of crust material in its mantle source. | CHEN Daogong WANG Xiang E.Deloule LI Binxian XIA Qunke CHENG Hao WU Yuanbao | 2001 | Chinese Science Bulletin2001，46，12： | 4 |
| 8 | Hydrogen isotope compositions of mantle-derived amphibole megacrysts from Qilin, Guangdong and its tectonic significance显示文摘Hydrogen isotope compositions of mantle-derived amphibole megacrysts from Qilin, Guang dong Province have been obtained by ion micro-probe. δD and H contents are constant both among different samples and within single sample, demonstrating that their formation condition is very stable.High δD values suggest the presence of a component recycled from crust which is possibly related to the subduction of Pacific Plate beneath Eurasian Plate in Mesozoic. | Qunke Xia Daogong Chen Deloule Etienne Xiachen Zhi | 1999 | Chinese Science Bulletin1999，44，5： | 2 |

| 11 | Oxygen isotopic heterogeneity in the mantle: Evidence from clinopyroxene megacrysts of Nüshan, eastern China显示文摘Major element, REE and oxygen isotopic com-positions of fourteen clinopyroxene megacrysts from Nushan, eastern China have been obtained. They are believed to rep-resent crystallization products of one mantle-derived alkali basaltic magma. Oxygen isotopic ratios are homogeneous within the same sample, but heterogeneous among different samples, δ18O values of these megacrysts are from 4.86‰ to 6.48‰. We suggest that the oxygen isotopic variation of cli-nopyroxene megacrysts should be inherited from their source magma, and the heterogeneity of source magma re-sults from contamination of subducted oceanic materials. | XIA Qunke Dallai Luigi CAO Hong CHEN Daogong WU Yuanbao CHENG Hao | 2002 | Chinese Science Bulletin2002，47，3： | 1 |

| 13 | Ammonium Impacts on Vibrations of Hydroxyl and Lattice of Phengite at High Temperature and High Pressure显示文摘Dehydration in hydrous phases of the downgoing slab controls water release processes in subduction zones. Interplay between volatiles in hydrous minerals has complicated the previous knowledge of their dehydration. Phengite is an essential mineral carrying both hydrogen and nitrogen to the deep Earth. To further understand the link between nitrogen and dehydration process of phengite at an atomic level, we here carry out high temperature and high pressure vibrational spectroscopic investigations on hydroxyl and lattice of ammonium-bearing and ammonium-free phengites. The results show that heating to 800 oC hardly influences hydroxyl bonding strength, whereas pressure induces strengthening of hydrogen bonding until 10 GPa. Moreover, hydrogen transits between the sites with increasing temperature and pressure. The lattice modes soften with increasing temperature and stiffen under compression. Ammonium has no effect on hydroxyl bonding strength, but hinders hydrogen transition at high temperatures and high pressures. Ammonium does not influence the lattice at high pressures either, but delays softening of the lattice at high temperatures. These data unveil behavior of hydroxyl and lattice in phengite at high temperature and high pressure, and also evaluate ammonium impacts, shedding new lights on dehydration processes of phengite during subduction. | Weihua Huang Yan Yang Zeming Qi Wendi Liu Zhongping Wang Yan Liu Qunke Xia | 2021 | Journal of Earth Science2021，32，5： | 0 |
| 14 | The distribution of water in the continental lithospheric mantle and its implications for the stability of continents显示文摘The lithospheric mantle is one of the key layers controlling the stability of continents.Even a small amount of water can influence many chemical and physical properties of rocks and minerals.Consequently,it is a pivotal task to study the distribution of water in the continental lithosphere.This paper presents a brief overview of the current state of knowledge about(1)the occurrence of water in the continental lithospheric mantle,(2)the spatial and temporal variations of the water content in the continental lithospheric mantle,and(3)the relationship between water content and continent stability.Additionally,suggestions for future research directions are briefly discussed. | XIA QunKe HAO YanTao | 2013 | Chinese Science Bulletin2013，58，32： | 0 |
