1An Archean continental block in the Taihangshan and Hengshan regions: Constraints from geochronology and geochemistry显示文摘Recent research on the tectonothermal evolution and geochronology in the Fuping, Hengshan and Wutaishan metamorphic complexes, together with the discoveries of a high-pressure granulite belt in the northern margin of the North China Craton (NCC) and high-pressure metapelites in the Jingangku Group of the Wutaishan complex, suggests that there was a Neoarchean to Paleoproterozoic orogenic belt related to collision between the Eastern and Western continental blocks. Comparison of geological, geochronological, tectonothermal and geochemical data between the Fuping and Hengshan complexes suggests these two complexes most likely originated and evolved as a single lithotectonic domain (i.e., the Taihangshan-Hengshan block) during the early evolution of the North China Craton, probably as an active margin to the Eastern Continental Block. The Taihangshan-Hengshan block has been subjected to intensive and extensive tectono-magmatism and high-grade metamorphism related to collision between the Eastern and Western continental blocks at ~1.80 Ga.LIU Shuwen , LI Jianghai, PAN Yuanming, ZHANG Jian and LI Qiugen(1.

2利用H_2O-Nacl-CaCl_2体系水盐化合物和冰的融化温度计算NaCl/(Nacl+CaCl_2)比值和盐度的方程显示文摘The composition of fluid inclusions in the H_2O-NaCl-CaCl_2 system has been generally graphically estimated using the melting temperatures of hydrohalite(T_(m-HH))and ice(T_(m-ice)).Here we present two equations that can be used to calculate the relative proportion of NaCl(i.e.,NaCl/[NaCl+CaCl_2],or X_(NaCl))and the total salinity( i.e.,NaC1 + CaC12,wt% )for fluid inclusions with ice as the last melting phase.X_(NaCl)can be calculated from T_(m-HH)using the following equation: y=(a+bx)^(-1/c) where y is X_(NaCl),x is T_(m-HH),a=0.33124402,b=-0.031518028,and c=0.22932736.In the cases where only T_(m-ice)is measured and T_(m-HH)is not known,T_(m-ice)can be used as the maximum possible TIn.nil to calculate the maximum value of X_(NaCl)using the above equation.In these cases,the following equation can be used to calculate the maximum total salinity: y=(a+bx+cx^2)^(-1) where y is salinity,x is T_(m-HH),a=0.057184817,b=0.00078565757,and c=5.7262766E-6.Because the isothems in the field of ice are sub-parallel to the NaCl-CaCl_2 binary side in the H20-NaC1-CaC12 ternary system,the errors in salinity calculation introduced by the above approximation are small(less than 2 wt% ).A Windows program for calculation of X_(NsCl)and salinity is available at: http://gffzz48c1abc75f37476dhbb0v0pofk9kc66qq.ffgz.tsg.suse.edu.cn/~chiguox.GuoXiang CHI~(1*) Pei NI~(2**) 1.Department of Geology,University of Regina,3737 Wascana Parkway,Regina,Saskatchewan,Canada S4S 0A2 2.State Key Laboratory for Mineral Deposit Research,Institute of Geo-fluid Research,Department of Earth Science,Nanjing University,Nanjing 210093,China 2007岩石学报2007,23,1:18

5配电网自适应保护系统的设计与实现显示文摘本文介绍了一种以基于计算机的过电流继电器来保护配电网的自适应系统的设计,概述了实现一个自适应系统所必需的软件和硬件,指出用于保护相对地故障的过电流继电器既要适应系统负荷和发电的变化,也要适应系统拓扑的变化。为研究自适应继电器的性能,作者考虑了被选定网络的四种运行状态。研究结果表明,采用自适应方法可以加快继电器的动作并改善保护系统的选择性。本文还给出了在自适应系统发生局部或全面故障时应当采用的运行策略的建议。M.S.Sachdev T.S.Sidhu B.K.

10A Method for Non-Lipschitz Programming via an Exact Penalry Function显示文摘A descent algorithm for Non-Lipschitz Programming is presented in the paper. The algorithm employs a strict convex programming to obtain a search direction and an exact penalty function to determine step lenth. The convergence is proved and two numerical results are given, in which the objective functions are discontinuous.Hang Jiqing (Department of Mathematics, Univeceity of Saskatchewan, Canada) 1990经济数学1990,8,1:1

13Discovery of Jinning Cycle Magmatism in Eastern Part of Eastern Kunlun Orogenic Belt and Its Significance显示文摘From the isotopic dating study of gneissic granodiorite, the authors discovered magmatism of the Jinning cycle. Intrusive rocks were formed in the Neoproterozoic, whose Pb Pb ages range from (913±4) Ma to (1 011±4) Ma and U Pb concordia age is (703±15) Ma. The tectonic settings of the rocks are volcanic arc or syn collision. After the formation of the intrusive rocks, these rocks also experienced reconstruction of Caledonian metamorphism. Based on the Ar Ar dating of metamorphic mineral of muscovite, the metamorphic time is determined to range from (386.8±0.8) Ma to (389.44±3.70) Ma.Zhu Yunhai Faculty of Earth Sciences, China University of Geosciences, Wuhan 430074, China Pan Yuanming Department of Geological Sciences, University of Saskatchewan, Saskatoon, Canada Zhang Kexin Faculty of Earth Sciences, China University of G 2000Journal of Earth Science2000,19,3:0
14A New Model for Correlating the Solubility of Solids in Supercritical CO_2 and Study on Some Systems(Ⅱ): Correlation and Prediction显示文摘The solubilities of a number of solid solutes in supercritical CO2 have been correlated usingthe model proposed in previous paper. The numbers of CO2 in each CO2 -solute cluster and the localdensity of the CO2 in the clusters are predicted using the model. The results calculated agree fairly wellwith the experimental data.Ming Hong ZHONG Bu Xing HAN Jie KE Zhi Min LIU Hai Ke YAN Ding Yu PENG(Institute of Chemistry, Academia Sinica, Beijing, 100080)(Department of Chemical Engineering, University of Saskatchewan, Saskatoon S7N 5C9, Canada) 1998Chinese Chemical Letters1998,9,3:0

18Introduction to thematic section on hydrodynamic studies of mineralization显示文摘1.Introduction Most metallic mineral deposits formed from hydrothermal fluids,and the mineralization processes include both chemical (e.g.,fluid-rock and fluid-fluid interactions)and physical(e.g., fluid flow)aspects.More attention has been paid to the chemical processes than the physical ones,even though the latter is equally important in controlling the formation of mineral deposits and their localization.Nevertheless,a number of studies have been carried out regarding the hydrodynamics of fluid flow associated with ore mineralization(e.g.,Cathles,1981,1997; Garven and Raffensperger,1997;Cathles and Adams,2005; Cox,2005;Ingebritsen et al.,2006),and it is timely to eval-Guoxiang Chi Department of Geology,University of Regina, Regina,Saskatchewan,Canada Chunji Xue State Key Laboratory of Geological Processes and Mineral Resources,China University of Geosciences, Xueyuan Road 29,Beijing 100083,China 2011Geoscience Frontiers2011,2,3:0
