| 1 | Zircon U-Pb dating confirms existence of a Caledonian scheelite-bearing aplitic vein in the Penggongmiao granite batholith, South Hunan显示文摘Granite at Penggongmiao is a large batholith in the Nanling Range, with an outcrop area of over 900 km 2 . There are many scheelite-quartz veins around the granite. LA-ICP-MS U-Pb dating was carried out for zircons from the granite. The middlecoarse-grained biotite granite has U-Pb ages of 435 to 436 Ma. Ages of 426.5±2.5 Ma were obtained for aplitic dyke cross-cutting the granite. The scheelite of magmatic origin in the aplite dyke was identified from petrographic investigation. This demonstrates that W-bearing granites of Early Paleozoic (corresponding to the Caledonian orogensis in the traditional sense) occur in the Nanling Range. This finding has important implications for the ore-forming potential of Paleozoic granites and on the extent of Mesozoic mineralization. Thus it merits performing an intensive study of Paleozoic granites in South China. The occurrences of aplite or microgranite may be an indicative of the Caledonian tungsten granites and associated W mineralization. | ZHANG WenLan WANG RuCheng LEI ZeHeng HUA RenMin ZHU JinChu LU JianJun XIE Lei CHE XueDong ZHANG RongQing YAO Yuan CHEN Jun | 2011 | Chinese Science Bulletin2011,56,19: | 23 |
| 2 | Chronology,Hf isotopes,geochemistry,and petrogenesis of the magmatic rocks in the Shizishan ore field of Tongling,Anhui Province显示文摘LA-ICPMS zircon U-Pb dating of intrusive rocks from the Shizishan ore field,Tongling,Anhui Province shows that the crystallization ages of Baimangshan pyroxene diorite,Shizishan and Dongguashan quartz diorite are 139±1.9,138.0±1.7,and 138.4±1.7 Ma,respectively.These three intrusions are high-potassium,alkali-rich,meta-aluminous,and are characterized by enrichment of light rare earth elements and large-ion lithophile elements,depletion of heavy rare-earth elements(HREE) and high field strength elements,and slightly negative Eu anomalies.In-situ Hf analysis of zircon for these three intrusions shows large ranges of Hf isotope compositions:the ε Hf(t) values are ε Hf(t)= 3.3 to 14.4 for Baimangshan,14.1 to 23.9 Dongguashan,and 14.7 to 26.9 for Shizishan.The ε Hf(t) values of both the Dongguashan and Shizishan quartz diorites are significantly lower than those of Baimangshan pyroxene diorite.Elemental geochemistry and in-situ zircon Hf isotope analyses indicate that the three intrusions were formed through mixing of granitic magma formed by partial melting of the lower crust and water-rich basic magma derived from the enriched lithospheric mantle.The Dongguashan and Shizishan quartz diorites involved greater crustal components than Baimangshan pyroxene diorite.The Dongguashan and Shizishan quartz diorites have geochemical features similar to the adakite,such as high Sr,low Y,and high Sr/Y ratios.Such geochemical features can be attributed to some fractional crystallization of apatite and sphene,and insignificant plagioclase fractional crystallization after magma mixing.These three intrusions are the products of complex crust-mantle interaction during the regional tectonic regime transition from compression to extension. | GUO WeiMin LU JianJun JIANG ShaoYong ZHANG RongQing ZHAO ZhanJie | 2013 | Science China Earth Sciences2013,56,6: | 15 |
| 3 | 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 |
| 4 | Re-Os isotope dating of pyrite from the footwall mineralization zone of the Xinqiao deposit,Tongling,Anhui Province:Geochronological evidence for submarine exhalative sedimentation显示文摘The Xinqiao deposit is located in the Tongling area,Anhui Province.This deposit is dominantly composed of stratiform sulfide orebodies,which are restricted to the transitional zone from clastic rocks to carbonates at the base of the Late Carboniferous Huanglong Formation.There are discordant veinlets or networks of mineralization in the footwall rocks below the stratiform sulfide orebodies.The underlying discordant mineralization zones coexist with conformable stratiform sulfide orebodies,which are considered to be the most representative features of massive sulfide deposits formed by submarine exhalative sedimentation.This study reports a pyrite 187Re-187Os isotopic age of 319±13 Ma(MSWD=16) for the footwall mineralization zone.This isochron age is consistent with the interval of strata hosting the conformable stratiform sulfide orebody,and provides direct geochronological evidence for Carboniferous exhalative sedimentary mineralization. | GUO WeiMin LU JianJun JIANG ShaoYong ZHANG RongQing QI Liang | 2011 | Chinese Science Bulletin2011,56,35: | 11 |

| 6 | Skarn-type tungsten mineralization associated with the Caledonian(Silurian) Niutangjie granite, northern Guangxi, China显示文摘The Niutangjie tungsten deposit is a bedded skarn-type scheelite deposit and is located at the junction between Ziyuan and Xingan counties in the north of Guangxi,China.The deposit is genetically related to a fine-grained two-mica granite within the orefield.Zircon LA-ICP-MS U-Pb dating of the granite yielded a Silurian(Caledonian)age of 421.8±2.4 Ma,which is contemporaneous with the adjacent Yuechengling batholith.Mineralization within the skarn is associated with a quartz,garnet,and diopside gangue,and scheelite is present in a number of different mineral assemblages,such as quartz-scheelite and quartz-sulfide-scheelite;these assemblages correspond to oxide and sulfide stages of mineralization.Sm-Nd isotope analysis of scheelite yielded an isochron age of 421±24 Ma.Although the uncertainty on this date is high,this age suggests that the scheelite mineralization formed during the Late Caledonian,at a similar time to the emplacement of the Niutangjie granite.Zircons within the granite have?Hf(t)values and Hf two-stage model ages of?6.5 to?11.6,and 1.79 to 2.11 Ga,respectively.These data suggest that the magma that formed the granite was derived from Mesoproterozoic crustal materials.Scheelite?Nd(t)values range from?13.06 to?13.26,also indicative of derivation from ancient crustal materials.Recent research has identified Caledonian magmatism in the western Nanling Range,indicating that this magmatism may be the source of contemporaneous tungsten mineralization. | YANG Zhen WANG RuCheng ZHANG WenLan CHU ZhuYin CHEN Jun ZHU JinChu ZHANG RongQing | 2014 | Science China Earth Sciences2014,57,7: | 11 |
| 7 | Petrogenetic differences between the Middle-Late Jurassic Cu-Pb-Zn-bearing and W-bearing granites in the Nanling Range,South China: A case study of the Tongshanling and Weijia deposits in southern Hunan Province显示文摘The Middle-Late Jurassic Cu-Pb-Zn-bearing and W-bearing granites in the Nanling Range have distinctly different mineralogical and geochemical signatures. The Cu-Pb-Zn-bearing granites are dominated by metaluminous amphibole-bearing granodiorites, which have higher CaO/(Na2O+K2O) ratios, light/heavy rare earth element(LREE/HREE) ratios, and δEu values,lower Rb/Sr ratios, and weak Ba, Sr, P, and Ti depletions, exhibiting low degrees of fractionation. The W-bearing granites are highly differentiated and peraluminous, and they have lower CaO/(Na2O+K2O) ratios, LREE/HREE ratios, and δEu values,higher Rb/Sr ratios, and strong Ba, Sr, P, and Ti depletions. The Cu-Pb-Zn-bearing granites were formed predominantly between155.2 and 167.0 Ma with a peak value of 160.6 Ma, whereas the W-bearing granites were formed mainly from 151.1 to 161.8Ma with a peak value of 155.5 Ma. There is a time gap of about 5 Ma between the two different types of ore-bearing granites.Based on detailed geochronological and geochemical studies of both the Tongshanling Cu-Pb-Zn-bearing and Weijia W-bearing granites in southern Hunan Province and combined with the other Middle-Late Jurassic Cu-Pb-Zn-bearing and W-bearing granites in the Nanling Range, a genetic model of the two different types of ore-bearing granites has been proposed. Asthenosphere upwelling and basaltic magma underplating were induced by the subduction of the palaeo-Pacific plate. The underplated basaltic magmas provided heat to cause a partial melting of the mafic amphibolitic basement in the lower crust, resulting in the formation of Cu-Pb-Zn mineralization related granodioritic magmas. With the development of basaltic magma underplating,the muscovite-rich metasedimentary basement in the upper-middle crust was partially melted to generate W-bearing granitic magmas. The compositional difference of granite sources accounted for the metallogenic specialization, and the non-simultaneous partial melting of one source followed by the other brought about a time gap of about 5 Ma between the Cu-Pb-Zn-bearing and W-bearing granites. | HUANG XuDong LU JianJun Stanislas SIZARET WANG RuCheng MA DongSheng ZHANG RongQing ZHAO Xu WU JinWei | 2017 | Science China Earth Sciences2017,60,7: | 9 |
| 8 | Petrogenesis of the concealed Daqiling intrusion in Guangxi and its tectonic significance: Constraints from geochemistry, zircon U-Pb dating and Nd-Hf isotopic compositions显示文摘The samples from the hidden Daqiling muscovite monzonite granite, which has recently been recognized within the Limu Sn-polymetallic ore field, have been analyzed for zircon U-Pb ages and whole rock geochemical and Nd-Hf isotopic compositions to discuss its genesis, source, and tectonic setting. LA-ICP-MS zircon U-Pb dating indicates that the granite crystallized in the late Indosinian(224.8±1.6 Ma). The granite is enriched in SiO2 and K2 O and low in CaO and Na2 O. It is strongly peraluminous with the A/CNK values of 1.09–1.20 and 1.4 vol%–2.7 vol% normal corundum. Chondrite-normalized REE patterns show slightly right-dipping shape with strongly negative Eu anomalies(δEu =0.08–0.17). All samples show enrichment of LILEs(Cs, Rb and K) and HFSEs(U, Pb, Ce and Hf), but have relatively low contents of Ba, Sr and Ti. The zircon saturation temperatures(Tzr) are from 711 to 740℃, which are slightly lower than the average value of typical S-type granite(764℃). The granite has negative εNd(t) and εHf(t) values, which change from -9.1 to -10.1 with the peak values of -9.2 to -9.0 and from -3.7 to -12.6 with the peak values of -6 to -5, respectively. The C DMT(Nd) and C DMT(Hf) values are 1.74–1.82 Ga with the peak values of 1.73–1.75 Ga and 1.49–2.04 Ga with the peak values of 1.5–1.6 Ga, respectively. These characteristics reveal that the source region of the granite is dominantly late Paleoproterozoic to early Mesoproterozoic crustal materials. Seven inherited magmatic zircons are dated at the age of 248.6±4.3 Ma, which suggests the existence of the early Indosinian granite in Limu area. These zircons have the εHf(t) values of -6.7– -2.3, similar to those of the Daqiling granite, implying the involvement of the early Indosinian granite during the formation of the Daqiling granite. Inherited zircon of 945±11 Ma has the εHf(t) and TDM(Hf) values of 8.7 and 1.14 Ga, respectively, compatible with those of the Neoproterozoic arc magmatic rocks in the eastern Jiangnan orogenic belt. Therefore we inferred that Neoproterozoic arc magma might have been involved in the formation of the Daqiling granite, and that the Neoproterozoic arc magma belt and continent-arc collision belt between the Yangtze and Cathaysia Blocks might have extended westsouthward to Limu region. It is proposed that the underplating of mantle materials triggered by crustal extension and thinning resulted in partial melting of crustal materials to form the Daqiling granite in the late Indosinian under post-collisional tectonic setting. | ZHANG HuaiFeng LU JianJun WANG RuCheng MA DongSheng ZHU JinChu ZHANG RongQing | 2014 | Science China Earth Sciences2014,57,8: | 6 |

| 10 | Interference-Free Pilot Design and Channel Estimation Using ZCZ Sequences for MIMO-OFDM-Based C-V2X Communications显示文摘Cellular vehicle-to-everything(C-V2X) communications is regarded as a promising and feasible solution for 5G-enabled vehicular communications and networking. In this paper, we investigate the pilot design and channel estimation problem in MIMO-OFDM-based C-V2X systems with severe co-channel interference due to spectrum reusing among different V2X communication links. By using zero-correlation zone(ZCZ) sequences, we provide an interference-free pilot design scheme and a corresponding time-domain(TD) correlation-based channel estimation(TD-CCE) method. We employ the ZCZ sequences from the same family set to be designed as the TD pilot symbols and guarantee the pilot sequeneces for neighboring V2X communication links are code-division multiplexing(CDM). The co-channel pilot interference of the deisgned pilot symbols can be effectively eliminated by exploiting the provided TD-CCE method. Simulation results indicate that the accuracy of channel estimation can be effectively improved by the proposed scheme, whose performance is close to that of the non-interference situation. | Haibin Chen Rongqing Zhang Wenjun Zhai Xiaoli Liang Guojuan Song | 2018 | China Communications2018,15,7: | 5 |

| 13 | Erosion of the prismatic layer by the organic matrix during the formation of the nacre-prism transition layer in the shell of Pinctada fucata (Bivalvia, Mollusca)显示文摘Three variants of the sequence of formation of the nacre-prism transition layer were observed in Pinctada fucata (Bivalvia, Mollusca) shells. In each case, the layer was formed by the organic matrix secreted by the mantle, together with the interprismatic organic envelope. The continuity of the organic phase throughout the shell was maintained as the new nacreous layer was formed on the nacre-prism transition layer. Changes in the interprismatic organic envelopes on either side of the nacre-prism transition zone indicated that the organic matrix of the nacre-prism transition layer becomes embedded into the organic phase of the prismatic layer. It is concluded that penetration and erosion of the prisms by the organic matrix generates a strong bond between the prismatic and nacreous layers. | LIU XiaoJun LIU Chang SUN Juan ZHOU YuJuan ZHENG GuiLan ZHANG GuiYou WANG HongZhong XIE LiPing ZHANG RongQing | 2011 | Chinese Science Bulletin2011,56,9: | 3 |
| 14 | Calibration of the simulation parameters of the particulate materials in film mixed materials显示文摘In order to obtain accurate contact parameters of a particulate material in residual film mixture collected by cotton field machine in Xinjiang,the angle of repose test and inclined plane test were carried out.In the tests,the angles of repose of the particulate material with the water content of(6.26±1.5)%and(14.1±2.1)%were measured respectively,as well as the static sliding friction angle between the particulate material and the residual film.At the same time,the EDEM software was used to calibrate the coefficient of restitution,static friction coefficient and dynamic friction coefficient between the material and the film.Then,the second-order response model between contact parameters and the angle of repose and static sliding friction angle was constructed.In addition,the optimal contact parameters between the granular materials and the mulch were obtained by fitting the physical test data.The results indicated that the errors between the physical test results and the numerical simulation results are small.It was proved that the second-order response model could predict the repose angle of granular materials and the static sliding friction angle between granular materials and farmland film.This study could provide theoretical support for the subsequent model construction of the residual film mixture collected by the cotton field machine. | Rongqing Liang Xuegeng Chen Peng Jiang Bingcheng Zhang Hewei Meng Xiangbin Peng Za Kan | 2020 | International Journal of Agricultural and Biological Engineering2020,13,4: | 3 |

| 16 | Rapid and reversible Na deposition onto Al nanosheet arrays显示文摘Sodium metal battery(SMB)is regarded as a promising candidate for next-generation high-energy battery due to high theoretical capacity and abundant natural resources.However,the growth of sodium dendrites and large volume expansion during the processes of sodium plating and stripping seriously restrict the practical application of SMBs.Here,a three-dimensional skeleton of aluminum nanosheet arrays(Al NSARs)is constructed by a facile etching approach to achieve rapid and reversible Na plating/stripping.The Al NSARs with large geometric specific surface and plentiful cavities can provide rich active nucleation sites,reduce local current density and accommodate Na volume change,which lead to uniform deposition of sodium with dendrite-free morphology.As a result,Na plating/stripping on Al NSARs can stably operate over 650 cycles at 2 mA cm^(-2)/2 mAh cm^(-2)with average Coulombic efficiency(CE)of 100.0%and low potential polarization of 27 mV.Moreover,the full cell of Na_(s)V_(2)(PO_(4))_(3)||Al NSARs@Na can run for over 1800 cycles at a high rate of 20C.These superior properties,combined with relatively low cost and weight of Al,enable our AlNSARs to begreat prospect for practical applications. | Fang Tang Rongqing Xia Dong Chen Yu Yao Lin Liu Yuezhan Feng Xianhong Rui Yan Yu | 2022 | Journal of Energy Chemistry2022,31,11: | 3 |
| 17 | Substitution of Ni for Zn on microstructure and mechanical properties of Mg-Gd-Y-Zn-Mn alloy显示文摘This study analyzes the effect of substitution of Ni for Zn on microstructure and mechanical properties of Mg-Gd-Y-Zn-Mn alloy.Our results show that the volume fraction of Mg5(Gd,Y)and(Mg,Zn)3RE phase decreased and LPSO phase increased with more substitution of Ni.After homogenization,onlyα-Mg and LPSO phase existed.In Mg-Gd-Y-Zn-Mn alloys,the LPSO phases mainly consisted of the 14H type.While in Mg-Gd-Y-Ni-Mn alloy,the LPSO phases consisted of the 18R type.In addition,compared with Mg-Gd-Y-Zn-Mn alloy,the mechanical properties of as-extruded Ni-substitution alloys were improved due to the better refinement of the size of grains and LPSO phases.The tensile strength in as-extruded Mg-Gd-Y-Ni-Mn alloy could reach up to 400 MPa with 18%of the elongation to failure. | Rongqing Zhang Jingfeng Wang Song Huang Shijie Liu Fusheng Pan | 2017 | Journal of Magnesium and Alloys2017,5,3: | 3 |

| 20 | A framework for multi-robot motion planning from temporal logic specifications显示文摘We propose a framework for the coordination of a network of robots with respect to formal requirement specifications expressed in temporal logics.A regular tessellation is used to partition the space of interest into a union of disjoint regular and equal cells with finite facets,and each cell can only be occupied by a robot or an obstacle.Each robot is assumed to be equipped with a finite collection of continuous-time nonlinear closed-loop dynamics to be operated in.The robot is then modeled as a hybrid automaton for capturing the finitely many modes of operation for either staying within the current cell or reaching an adjacent cell through the corresponding facet.By taking the motion capabilities into account,a bisimilar discrete abstraction of the hybrid automaton can be constructed.Having the two systems bisimilar,all properties that are expressible in temporal logics such as Linear-time Temporal Logic,Computation Tree Logic,and μ -calculus can be preserved.Motion planning can then be performed at a discrete level by considering the parallel composition of discrete abstractions of the robots with a requirement specification given in a suitable temporal logic.The bisimilarity ensures that the discrete planning solutions are executable by the robots.For demonstration purpose,a finite automaton is used as the abstraction and the requirement specification is expressed in Computation Tree Logic.The model checker Cadence SMV is used to generate coordinated verified motion planning solutions.Two autonomous aerial robots are used to demonstrate how the proposed framework may be applied to solve coordinated motion planning problems. | T.John KOO RongQing LI Michael M.QUOTTRUP Charles A.CLIFTON Roozbeh IZADI-ZAMANABADI Thomas BAK | 2012 | Science China(Information Sciences)2012,55,7: | 2 |
