| 2 | Re-Os geochronology of Cu and W-Mo deposits in the Balkhash metallogenic belt,Kazakhstan and its geological significance显示文摘<正>The Central Asian metallogenic domain(CAMD) is a multi-core metallogenic system controlled by boundary strike-slip fault systems.The Balkhash metallogenic belt in Kazakhstan,in which occur many large and super-large porphyritic Cu—Mo deposits and some quartz vein- and greisen-type W—Mo deposits,is a well-known porphyritic Cu—Mo metallogenic belt in the CAMD.In this paper 11 molybdenite samples from the western segment of the Balkhash metallogenic belt are selected for Re—Os compositional analyses and Re—Os isotopic dating.Molybdenites from the Borly porphyry Cu deposit and the three quartz vein-greisen W—Mo deposits—East Kounrad.Akshatau and Zhanet—all have relatively high Re contents(2712—2772μg/g for Borly and 2.267—31.50μg/g for the other three W—Mo deposits),and lower common Os contents(0.670—2.696 ng/g for Borly and 0.0051—0.056 ng/g for the other three).The molybdenites from the Borly porphyry Cu—Mo deposit and the East Kounrad,Zhanet,and Akshatau quartz vein- and greisen-type W—Mo deposits give average model Re—Os ages of 315.9 Ma,298.0 Ma,295.0 Ma,and 289.3 Ma respectively.Meanwhile,molybdenites from the East Kounrad,Zhanet,and Akshatau W—Mo deposits give a Re—Os isochron age of 297.9 Ma,with an MSWD value of 0.97.Re-Os dating of the molybdenites indicates that Cu—W—Mo metallogenesis in the western Balkhash metallogenic belt occurred during Late Carboniferous to Early Permian(315.9—289.3 Ma),while the porphyry Cu—Mo deposits formed at—316 Ma,and the quartz vein-greisen W—Mo deposits formed at ~298 Ma.The Re—Os model and isochron ages thus suggest that Late Carboniferous porphyry granitoid and pegmatite magmatism took place during the late Hercynian movement.Compared to the Junggar-East Tianshan porphyry Cu metallogenic belt in northwestern China,the formation of the Cu—Mo metallogenesis in the Balkhash metallogenic belt occurred between that of the Tuwu-Yandong in East Tianshan and the Baogutu porphyry Cu deposits in West Junggar. Collectively,the large-scale Late Carboniferous porphyry Cu—Mo metallogenesis in the Central Asian metallogenic domain is related to Hercynian tectono-magmatic activities. | Xuanhua Chen Wenjun Qu Shuqin Han Seitmuratova Eleonora Nong Yang Zhengle Chen Fagang Zeng Andao Du Zhihong Wang | 2010 | Geoscience Frontiers2010,1,1: | 10 |
| 3 | Dynamic Positioning System Based on Active Disturbance Rejection Technology显示文摘A dynamically positioned vessel, by the International Maritime Organization(IMO) and the certifying class societies(DNV, ABS, LR, etc.), is defined as a vessel that maintains its position and heading(fixed location or pre-determined track) exclusively by means of active thrusters. The development of control technology promotes the upgrading of dynamic positioning(DP) systems. Today there are two different DP systems solutions available on the market: DP system based on PID regulator and that based on model-based control. Both systems have limited disturbance rejection capability due to their design principle. In this paper, a new DP system solution is proposed based on Active Disturbance Rejection Control(ADRC) technology. This technology is composed of Tracking-Differentiator(TD), Extended State Observer(ESO) and Nonlinear Feedback Combination. On one hand, both TD and ESO can act as filters and can be used in place of conventional filters; on the other hand, the total disturbance of the system can be estimated and compensated by ESO, which therefore enhances the system's disturbance rejection capability. This technology's advantages over other methods lie in two aspects: 1) This method itself can not only achieve control objectives but also filter noisy measurements without other specialized filters; 2) This method offers a new useful approach to suppress the ocean disturbance. The simulation results demonstrate the effectiveness of the proposed method. | LEI Zhengling GUO Chen FAN Yunsheng | 2015 | Journal of Ocean University of China2015,14,4: | 3 |

| 8 | Chronological Constraints on Late Paleozoic Collision in the Southwest Tianshan Orogenic Belt, China: Evidence from the Baleigong Granites显示文摘The Baleigong granites, located in the western part of the southwestern Tianshan Orogen(Kokshanyan region, China), records late Paleozoic magmatism during the late stages of convergence between the Tarim Block and the Central Tianshan Arc Terrane. We performed a detailed geochronological and geochemical study of the Baleigong granites to better constrain the nature of collisional processes in the Southwest Tianshan Orogen. The LA-ICP-MS U-Pb zircon isotopic analyses indicate that magmatism commenced in the early Permian(~282 Ma). The granite samples, which are characterized by high contents of SiO2(67.68-69.77 wt%) and Al2O3(13.93-14.76 wt%), are alkali-rich and Mg-poor, corresponding to the high-K calc-alkaline series. The aluminum saturation index(A/CNK) ranges from 0.93 to 1.02, indicating a metaluminous to slightly peraluminous composition. Trace element geochemistry shows depletions in Nb, Ta, and Ti, a moderately negative Eu anomaly(δEu=0.40-0.56), enrichment in LREE, and depletion in HREE((La/Yb)N=7.46-11.78). These geochemical signatures are characteristic of an I-type granite generated from partial melting of a magmatic arc. The I-type nature of the Baleigong granites is also supported by the main mafic minerals being Fe-rich calcic hornblende and biotite. We suggest that the high-K, calc-alkaline I-type granitic magmatism was generated by partial melting of the continental crust, possibly triggered by underplating by basaltic magma. These conditions were likely achieved in a collisional tectonic setting, thus supporting the suggestion that closure of the South Tianshan Ocean was completed prior to the Permian and was followed(in the late Paleozoic) by collision between the Tarim Block and the Central Tianshan Arc Terrane. | HUO Hailong CHEN Zhengle ZHANG Qing HAN Fengbin ZHANG Wengao SUN Yue YANG Bin TANG Yanwen | 2019 | Acta Geologica Sinica(English Edition)2019,93,5: | 1 |

| 11 | Characteristics of Ore-forming Fluid of the Gaoshan Gold-Silver Deposit in the Longquan Area, Zhejiang Province and its Implications for the Ore Genesis显示文摘The Gaoshan gold-silver deposit, located between the Yuyao-Lishui Fault and JiangshanShaoxing fault in Longquan Area, occurs in the Suichang-Longquan gold-silver polymetallic metallogenic belt. This study conducted an investigation for ore-forming fluids using microthermometry, D-O isotope and trace element. The results show that two types of fluid inclusions involved into the formation of the deposit are pure liquid phase and gas-liquid phase aqueous inclusions. The homogenization temperature and salinity of major mineralization phase ranges from 156°C to 236°C(average 200°C) and 0.35% to 8.68%(NaCleqv)(average 3.68%), respectively, indicating that the ore-forming fluid is characteristic of low temperature and low salinity. The oreforming pressure ranges between in 118.02 to 232.13'105 pa, and it is estabmiated that the oreforming depth ranges from 0.39 to 0.77 km, indicating it is a hypabyssal deposit in genesis. The low rare earth elements content in pyrites, widely developed fluorite in late ore-forming stage and lack of chlorargyrite(Ag Cl), indicates that the ore-forming fluid is rich in F rather than Cl. The ratios of Y/Ho, Zr/Hf and Nb/Ta of between different samples have little difference, indicating that the later hydrothermal activities had no effects on the former hydrothermal fluid. The chondrite-normalized REE patterns of pyrites from country rocks and ore veins are basically identical, with the characteristics of light REE enrichment and negative Eu anomalies, implying that the ore-forming fluid was oxidative and derived partly from the country rocks. The δD and δ18O of fluid inclusions in quartz formed during the main metallogenic stage range from -105‰ to -69 ‰ and -6.01‰ to -3.81‰, respectively. The D-O isotopic diagram shows that the metallogenic fluid is characterized by the mixing of formation water and meteoric water, without involvement of magmatic water. The geological and geochemical characteristics of the Gaoshan gold-silver deposit are similar to those of continental volcanic hydrothermal deposit, and could be assigned to the continental volcanic hydrothermal gold-silver deposit type. | JIANG Biao WANG Chenghui CHEN Yuchuan WU Baogui LIAO Peng CHEN Zhengle HAN Fengbin | 2016 | Acta Geologica Sinica(English Edition)2016,90,4: | 0 |

| 17 | Elephant Culture Matter for China’s Asian Elephants Conservation显示文摘Traditional anthropogenic impacts such as hunting,using as war-elephant,trading of ivory,paying tribute to the imperial court and so on,were once thought to be directly responsible for the rapid decline of Asian elephants in China.But in Yunnan Province,China,a unique human factor such as the traditional elephant culture of local ethnic minorities,is an important factor in the conservation of Asian elephants.In these areas,we investigated by means of village interviews,field surveys and data collection,the results show that the elephant culture of ethnic minorities has a great impact on people’s thoughts and behaviors,these traditional culture and belief(that mean taking elephant as the God,holding elephant as a belief,worshipping elephant and praise it)urges people to actively protect elephants and avoid more human-elephant conflicts.To enhance the public awareness of Asian elephant conservation,the Chinese Government or international environmental organizations should give higher attention and support to these elephant cultures. | Yongjing Tang Zhengling Li Guilian Jiang Ting Lv Lei Zhang Wenlan Zhao Gaofan Zhu Mingyong Chen | 2020 | Journal of Zoological Research2020,2,2: | 0 |
