| 1 | Geological Characteristics and Zircon U-Pb Dating of Volcanic Rocks from the Beizhan Iron Deposit in Western Tianshan Mountains, Xinjiang, NW China显示文摘The Beizhan large iron deposit located in the east part of the Awulale metallogenic belt in the western Tianshan Mountains is hosted in the Unit 2 of the Dahalajunshan Formation as lens, veinlets and stratoid, and both of the hanging wall and footwall are quartz-monzonite; the dip is to the north with thick and high-grade ore bodies downwards. Ore minerals are mainly magnetite with minor sulfides, such as pyrite, pyrrhotite, chalcopyrite and sphalerite. Skarnization is widespread around the ore bodies, and garnet, diopside, wollastonite, actinolite, epidote, uralite, tourmaline sericite and calcite are ubiquitous as gangues. Radiating outwards from the center of the ore body the deposit can be classified into skarn, calcite, serpentinite and marble zones. LA-ICP-MS zircon U-Pb dating of the rhyolite and dacite from the Dahalajunshan Formation indicates that they were formed at 301.3±0.8 Ma and 303.7±0.9 Ma, respectively, which might have been related to the continental arc magmatism during the late stage of subduction in the western Tianshan Mountains. Iron formation is genetically related with volcanic eruption during this interval. The Dahalajunshan Formation and the quartz-monzonite intrusion jointly control the distribution of ore bodies. Both ore textures and wall rock alteration indicate that the Beizhan iron deposit is probably skarn type. | ZHANG Zuoheng HONG Wei JIANG Zongsheng DUAN Shigang XU Lingang LI Fengming GUO Xincheng ZHAO Zhengang | 2012 | Acta Geologica Sinica(English Edition)2012,86,3: | 29 |

| 4 | Dextral-Slip Thrust Faulting and Seismic Events of the Ms 8.0 Wenchuan Earthquake,Longmenshan Mountains,Eastern Margin of the Tibetan Plateau显示文摘Dextral-slip thrust movement of the Songpan-Garzê terrain over the Sichuan block caused the M_s 8.0 Wenchuan earthquake of May 12,2008 and offset the Central Longmenshan Fault(CLF) along a distance of~250 km.Displacement along the CLF changes from Yingxiu to Qingchuan.The total oblique slip of up to 7.6 m in Yingxiu near the epicenter of the earthquake,decreases northeastward to 5.3 m,6.6 m,4.4 m,2.5 m and 1.1 m in Hongkou,Beichuan,Pingtong,Nanba and Qingchuan,respectively.This offset apparently occurred during a sequence of four reported seismic events,EQ1-EQ4,which were identified by seismic inversion of the source mechanism.These events occurred in rapid succession as the fault break propagated northeastward during the earthquake. Variations in the plunge of slickensides along the CLF appear to match these events.The Mw 7.5 EQ1 event occurred during the first 0-10 s along the Yingxiu-Hongkou section of the CLF and is characterized by 1.7 m vertical slip and vertical slickensides.The Mw 8.0 EQ2 event,which occurred during the next 10-42 s along the Yingxiu-Yanziyan section of the CLF,is marked by major dextralslip with minor thrust and slickensides plunging 25°-35°southwestward.The Mw 7.5 EQ3 event occurred during the following 42-60 s and resulted in dextral-slip and slickensides plunging 10°southwestward in Beichuan and plunging 73°southwestward in Hongkou.The Mw 7.7 EQ4 event, which occurred during the final 60-95 s along the Beichuan-Qingchuan section of the CLF,is characterized by nearly equal values of dextral and vertical slips with slickensides plunging 45°-50°southwestward.These seismic events match and evidently controlled the concentrations of landslide dams caused by the Wenchuan earthquake in Longmenshan Mountains. | WU Zhenhan DONG Shuwen Patrick J.

| 5 | Geology,Geochemistry and Zircon U-Pb Geochronology of Porphyries in the Dabate Mo-Cu Deposit,Western Tianshan,China:Petrogenesis and Tectonic Implications显示文摘The Dabate Mo-Cu deposit is a medium-sized porphyry-type deposit in the Sailimu Lake region, western Tianshan, China. We present the geology, geochemistry and zircon U-Pb geochronology of granite porphyries from the Dabate district with the intent to constrain their tectonic setting and petrogenesis. Porphyries in the Dabate district include granite porphyry I(gray white color with large phenocrysts), granite porphyry II(pink color with small phenocrysts) and quartz porphyry. Granite porphyry II is the Cu and Mo ore-bearing granitoid in the Dabate deposit. LA-ICPMS zircon U-Pb analyses indicate that granite porphyry II was emplaced at 284.2±1.8 Ma. Granite porphyry I and II have similar geochemical features and are both highly fractionated granites:(1) They have high SiO_2 content(70.93–80.18 wt% and 72.14–72.64 wt%, respectively), total alkali(7.58–8.95 wt% and 9.35–9.68 wt%, respectively), mafic index(0.95–0.98 and 0.93–0.94, respectively) and felsic index(0.79–0.94 and 0.89–0.91, respectively);(2) They are characterized by pronounced negative Eu anomaly, 'seagullstyle' chondrite-normalized REE patterns and 'tetrad effect' of REE;(3) They are rich in Rb, K, Th, Ta, Zr, Hf, Y and REE, but depleted in Sr, P, Ti and Nb. The magma of granite porphyries in Dabate can be interpreted to have been generated by partial melting of the upper crust due to mantle-derived magma underplating in a post-collisional extensional setting. | DUAN Shigang ZHANG Zuoheng WANG Dachuan LI Fengming | 2017 | Acta Geologica Sinica(English Edition)2017,91,2: | 7 |
| 6 | Geochronology,Geochemistry and Petrogenesis of Diabase Dyke Swarms in East Tianshan,Xinjiang,NW China显示文摘Diabase dyke swarms are widespread in the East Tianshan and Beishan regions. LA-ICP-MS zircon U-Pb ages of these diabase vary from 305 Ma to 278 Ma, showing that these dykes were formed during Late Carboniferous-Early Permian magmatism. All diabase samples are subalkali calc-alkali, characterized by slight LREE and LILEs enrichment, and weak negative Ti, Nb and Ta anomalies. The diabase samples have positive εNd(t) values (>+3), high Sr isotopic compositions (initial 87Sr/86Sr values=0.7030-0.7097), and large variation of Pb isotopic compositions, indicating they were derived from a deplete mantle source. Regional geology and geochemistry evidences indicate that these diabase dyke swarms were generated in a lithosphere extensional setting and had the same magma sources. Initial magmas may be a mixture of depleted asthenosphere mantle and enriched lithospheric mantle during rapid magma ascending. | ZHANG Zuoheng CHAI Fengmei WANG Tuanhua CHENG Yanbo XU Lingang YUAN Shunda | 2012 | Acta Geologica Sinica(English Edition)2012,86,6: | 5 |
| 7 | 胸腺恶性肿瘤预后的标准评估方法显示文摘胸腺恶性肿瘤相对少见,发病率约2.5-3.2/100万[1,2],病例也分散在各个医疗中心。现有文献几乎都是单中心的回顾性研究,为获得足够的病例,研究时间往往跨度几十年,报道结果的方式和使用的定义也各不相同,不同的研究结果很难比较。加之胸腺恶性肿瘤的进展、复发模式及致死原因等都具有其一定的特殊性,如何报道其结局显得十分重要。由于胸腺恶性肿瘤患者数量相对有限,从现有的经验中收集信息较为困难,而且存在过度描述和错误结论的风险。因此,专业胸腺肿瘤学术组织(International Thymic Malignacy Interest Group, ITMIG)对临床试验结果的报告制定了一套标准,已被该组织承担的合作项目采用。该标准的广泛应用将增强不同研究结果的可比性。只有采用统一的定义和规范的结果报告,胸腺肿瘤研究才能取得重要进展。2010年以前由外科医生、肿瘤内科医生和统计学家组成的小组共同回顾已有文献使用的评估方法形成初步的建议,再经过一个扩展小组审查,并最终将提炼的建议分发给所有ITMIG成员进行进一步讨论。最后在2010年5月6日的纽约年会上得到ITMIG的认可并被采用。本文就ITMIG标准作一综述。 | 付浩 中国胸腺瘤协作组全体成员 James Huang Frank C.Detterbeck Zuoheng Wang Patrick J.Loehrer | 2014 | 中国肺癌杂志2014,17,2: | 5 |
| 8 | U-Pb Zircon Dating of the Yeniutan Granitic Intrusion in the Western Sector of the North Qilian Mountains显示文摘Zircons from granodiorite and biotite granite in the Yeniutan granitic intrusion in the western North Qilian Mountains yielded a weighted mean 206Pb/238U apparent age of 460±3 Ma, suggesting that the intrusion originated during the late stage of plate subduction. Its related Ta’ergou and Xiaoliugou deposits are two of the few large tungsten deposits formed in the plate subduction environment in the world. The U-Pb dating of the zircons from the biotite granite gave a discordant lower intercept age of 183±4 Ma, which implies that the Yanshanian event was probably superimposed on the North Qilian region. | MAO Jingwen ZHANG Zuoheng JIAN Ping WANG Zhiliang YANG Jianmin ZHANG Zhaochong | 2000 | Acta Geologica Sinica(English Edition)2000,74,4: | 3 |

| 10 | Temporo-Spatial Distribution and Evolution of Ore Deposits in the West Sector of the Northern Qilian Mountains显示文摘The west sector of the northern Qilian Mountains is well-known for the Jingtieshan-type iron deposits. A new breakthrough has been made in prospecting for gold and copper in recent years. In this paper, the distribution characteristics of ore deposits in the study area are discussed from the viewpoint of tectonic evolution. It is suggested that there are 9 stages of mineralization from the Palaeoproterozoic to Indosinian. Four minerogenetic series and two minerogenetic subseries of ore deposits are recognized. Iron mineralization occurred in several stages, while most of the metals were accumulated in large amounts in the Caledonian. The enrichment and mineralization of gold is related to large-scale shear-strike-slip faults and the ascent and unloading of deep-seated fluids. | MAO Jingwen ZHANG Xiaoyu ZHANG Zhaochong REN Fengshou ZUO Guochao ZHANG Zuoheng YANG Jianmin WANG Zhiliang YE Dejin | 1999 | Acta Geologica Sinica(English Edition)1999,73,2: | 1 |

| 13 | Maximum likelihood estimation of nonlinear mixed-effects models with crossed random effects by combining first-order conditional linearization and sequential quadratic programming显示文摘Nonlinear mixed-eirects (NLME) modek have become popular in various disciplines over the past several decades.However,the existing methods for parameter estimation imple-mented in standard statistical packages such as SAS and R/S-Plus are generally limited k) single-or multi-level NLME models that only allow nested random effects and are unable to cope with crossed random effects within the framework of NLME modeling.In t his study,wc propose a general formulation of NLME models that can accommodate both nested and crassed random effects,and then develop a computational algorit hm for parameter estimation based on normal assumptions.The maximum likelihood estimation is carried out using the first-order conditional expansion (FOCE) for NLME model linearization and sequential quadratic programming (SCJP) for computational optimization while ensuring positive-definiteness of the estimated variance-covariance matrices of both random effects and error terms.The FOCE-SQP algorithm is evaluated using the height and diameter data measured on trees from Korean larch (L.olgeiisis var,Chang-paienA.b) experimental plots aa well as simulation studies.We show that the FOCE-SQP method converges fast with high accuracy.Applications of the general formulation of NLME models are illustrated with an analysis of the Korean larch data. | Liyong Fu Mingliang Wang Zuoheng Wang Xinyu Song Shouzheng Tang | 2019 | International Journal of Biomathematics2019,12,5: | 1 |
