摘 要：天山造山带不仅是中亚巨型造山带的组成部分，也是我国西部晚古生代岩浆活动的集中区，蕴含着丰富的古亚洲洋演化的复合地质信息。笔者以探索天山晚古生代花岗岩浆活动的物质来源为目标，采用Sr、Nd、Pb同位素地球化学方法，对该区不同构造单元中具有代表性的花岗岩体进行了全面系统的研究，发现天山不同构造单元中花岗岩Sr、Nd、Pb同位素特征具有明显差异。在与其围岩的同位素特征进行对比研究的基础上，提出了产于不同构造单元石炭—二叠纪花岗岩的可能源区。觉罗塔格石炭—二叠纪裂谷带的晚古生代花岗岩，具有最高的εNd(t)值和最低的（87Sr/86Sr）t值，如，以康古尔石英闪长岩为代表的二叠纪花岗岩的源岩可能是早期泥盆纪大南湖岛弧火山岩（新生地壳）；博格达地区的晚石炭—二叠纪花岗岩是早期基性火山岩，亦可能是底侵基性岩部分熔融的产物。中新元古代基底晚石炭—二叠纪裂谷带中花岗岩的源岩亦为同期基性火山岩，但在岩浆演化过程中受到古老基底地壳的混染，导致其εNd(t)值低于石炭—二叠纪裂谷带中花岗岩，而（87Sr/86Sr）t高于石炭—二叠纪裂谷带花岗岩。南天山东段和前寒武系微地块及其边缘中的晚古生代（含个别早古生代花岗岩）花岗岩分别是类似于库米什斜长角闪岩的古老地壳和西天山元古代古老地壳部分熔融的产物，因此它们均具有负的εNd(t)值和异常高的（87Sr/86Sr）t?值。上述认识对于了解天山晚古生代区域岩石圈演化及深部过程具有重要意义。?

摘 要：通过野外填图工作，在阿尔金断裂附近填绘出一系列的新生代地层，对这些地层目前的展布与阿尔金活动断裂的关系分析认为，始新世以来阿尔金断裂对沉积盆地表现出明显的控制作用，表现为明显的左行走滑，并兼具向北西方向掀斜的逆冲活动。乌尊硝尔盆地（索尔库里盆地西部）中的主体沉积是第四系。盆地的东南边界是阿尔金南缘主断裂；盆地西南缘，第四系沉积受东西向北倾正断层控制；盆地北缘为近东西向北倾右行逆冲脆性断裂。盆地的西部边缘超覆在基岩之上，不受断裂控制。?

井下电视与井下水质分析系统??
在鄂尔多斯地下水勘查项目的实施中，西安地质矿产研究所与国际原子能机构合作，引进了一套英国Geovista公司生产的井下电视与井下水质分析系统——Geovista Borehole Logging and Camera Systems 。利用该系统的井下水质分析系统，可连续测定钻孔中地下水的水温、电导率、pH值和含氧量等水文地质参数，利用这些参数可以了解弱透水层和隔水层对水质的影响，查明每一含水层的水质情况，为地下水的水质评价提供依据；该系统的井下电视系统部分可用于井下岩石结构观察，为井下施工提供依据。??

摘 要：从地貌和新构造的角度实际考察了龙羊峡，建立了共和盆地和龙羊峡地区构造抬升和变形的几何模型。根据模型笔者认为，黄河溯源侵蚀到达贵德盆地之后，龙羊峡西段由海拔3 000 m的夷平面封闭共和古湖，共和盆地周围的水体流向共和古湖；峡谷东段拉吉玛、罗汉堂地区已进行溯源侵蚀，水体向东流向贵得盆地。共和运动发生时，共和盆地作为一个完整的次级刚性活动块体被向东挤出和向东南微量顺时针旋转，同时，盆地的西端垂直构造抬升的幅度大于东端，共和古湖的水体重心向东偏移，水面越过海拔3 000 m的夷平面，向东流向贵德盆地，流水作用在两个盆地之间快速下切形成现今的龙羊峡。?

摘 要：通过对区内发育完好并保留下来的白垩纪—始新世地层的研究，海相白垩纪日喀则群自下而上可划分为昂仁组、帕达那组、曲贝亚组；古新世—始新世错江顶群包括下部曲下组和上部加拉孜组，整合覆于错江顶群之上的“如角藏布砂砾岩”为弧前盆地封盆粗碎屑岩。日喀则群与错江顶群在沉积学、地层古生物学及构造地质学诸方面的差异揭示了两群之间，更确切地说，曲贝亚组与曲下组之间呈不整合接触，该不整合形成于坎潘期—马斯特里赫特期与丹尼期之间。该区日喀则弧前盆地完整的地层序列全面再现了印度板块向欧亚板块俯冲过程，两板块的碰撞和新特提斯洋的彻底关闭发生在弧前盆地封盆粗碎屑岩沉积结束以后，这比原来认识的要晚些。?

摘 要：柴达木盆地西部干柴沟一带发育了大量湖相叠层石，主要存在于新近纪中新世地层中。柴西地区的叠层石形态各异，成因各具特点，而且部分叠层石与现代叠层石完全不同而是更类似于前寒武时期的对应物，根据国内外叠层石研究的最新成果和成因分类标准，柴西地区主要发育了骨架、凝集和细粒叠层石。对应于不同的分类标准其成因也各不相同，细粒叠层石的形成主要是通过微生物自身的钙化作用和生物膜上过饱和碳酸盐等物质以及微生物的引发的沉淀作用；凝集型叠层石的形成主要与原核生物和真核藻类共同发挥粘附作用有关；骨架型叠层石的形成主要是真核藻类等的钙化与原地碳酸盐的沉淀综合作用的结果。柴达木盆地频繁变化的湖相水体条件和周围的构造运动是叠层石形态多样，成因各异的主要外部和环境因素。对各类叠层石的深入细致研究将对沉积学和环境学的研究提供宝贵的现代对应物。?

摘 要：超临界流体具有一系列特殊性质，如，临界发散性、“临界乳光”、强氧化性、可变的介电常数、较强的溶解性等。地球深部超临界流体的存在不仅影响岩石的性质，而且对地质构造演化有重要的意义；超临界流体为油气的形成提供物质和能量，同时又是热液成矿过程中元素迁移、聚集和矿石矿物赋存空间形成的重要因素；地质构造演化与超临界流体密不可分；超临界流体对地震孕育及岩浆的产生和喷发有重要影响；超临界流体技术（超临界萃取、超临界水氧化等）不但能最大限度地回收有价值的矿物，而且能有效处理“三废”。?

摘 要：尽管秦岭泥盆系铅锌金多金属成矿带成矿作用均与热水喷流沉积作用有关，柞山地区却有别于凤太地区，具有独特的铜矿成矿背景。流体包裹体研究揭示了后生成矿流体的两阶段流体演化过程：第一阶段的成矿流体为中温，中高盐度岩浆热液含CO2的NaCl,H2O流体。均一温度为190～265oC，盐度12.5～35.34（wt%NaCl），压力12.8～21.3 MPa，在同一寄主矿物中均一温度变化小，而盐度变化极大，是岩浆流体沸腾的产物；第二阶段成矿流体为中高温，中高盐度岩浆期后热液NaCl,H2O流体。均一温度为300～350oC，盐度7.4～41.59(?wt%NaCl)，压力10.8~19.3 MPa。反映了岩浆期后热液流体的二次沸腾。应用流体地球化学的综合方法（包裹体流体组成、演化）识别出后生交代流体性质。穆家庄铜矿的成矿流体第一阶段为岩浆水，第二阶段的成矿流体为岩浆水加部分地层水（建造水）。氢氧同位素分析也支持上述结论。

Abstract：Aiming at the magmatic sources of Late Palaeozoic granites from Tianshan, this paper comprehensively and systemically discusses the representative granites from various tectonic units of Tianshan according to their Sr、Nd、Pb isotopic characteristics, and reveals many obvious differences in these granites.On the basis of comparison with the isotopic characteristics of their wall rocks, the potential sources of these granites are indicated.The Late-Palaeozoic granites in Carboniferous to Permian rift belt of Jueluotage have the highest εNd(t) values and the lowest (87Sr/86Sr)t?values, and the island?arc volcanic rocks (juvenile crust) of Devonian Dananhu Formation may be the potential source of Permian granites represented by the quartz diorites in Kangguer; the Late Carboniferous to Permian granites of Bogda area are probably the products of the partial melting of the contemporaneous basic volcanic or underplating basic magma.The source rock of the granites in the Carboniferous to Permian rift belts that have mesoproterozoic
neoproterozoic basements is the contemporaneous basic volcanic too, but may be
contaminated by the basement crust during the magma generation, which resulted
in the lower εNd(t) values and higher (87Sr/86Sr)t values of these granites than those of the granites of Carboniferous to Permian rift belts without Proterozoic basements.The Late-Palaeozoic granites (including some Early Palaeozoic granites) in east section of the Southern Tianshan and some Precambrain microcontinents or on their marginal are the partial melting products of the age old crust similar to plagihornblendite of K umishi and the Proterozoic crust of Western Tianshan respectively.These granites have the negative εNd(t) values and outstandingly high
(87Sr/86Sr)t values.The results above are significant to the study of Late Palaeozoic lithosphere evolution and deep process of Tianshan?

Abstract：On the basis of the field geologic, geomorphic, active tectonic observation and much more indoor research , we propose a dynamic model for the tectonic uplift and deformation of Gonghe basin and Longyang Gorgeregion Modeling suggests that the ancient Gonghe lake was closed by the planation surface of 3000m height above sea level in the west part of Longyang gorge after the getting of deriving erosion of Yellow river to Guide basin, around the Gonghe basin, the fluid flowed to the lake ;The east part of Longyang Gorge in Lajima and Luohantang area had been eroded to source, the fluid flowed to the Guide basin.When Gonghe movement took place, Gonghe basin,as a complete secondary rigidity active block, was extruded to east and rotated clockwise to southeast for little scale.Besides this,as its vertical uplifting displacement of west part was bigger than east the water barycenter of the ancient Gonghe lake deviated from west to east.So the water surface got across to 3000m planation surface, the water of ancient Gonghe lake flowed to Guide basin, then, Longyang Gorge had been formatted by the fast incision with the fluid between Gonghe basin and Guide basin.??

Abstract：Located in the west of Xigaze forearc basin, the Cretaceous to Eocene stratigrphic sequence reserved grows in the Zhongba region along the north bank of the Yarlung Zangbo Suture Zone.The marine Cretaceous Xigaze Gr could be subdivided in ascending order into the Angren Fm., Padana Fm. and Qubeiya Fm.,Pale ocene Eocene Cuojiangding Gr inclouds Quxia Fm.and Jialazi Fm.“Rujiaozangbu psepholite”—the confining coarse clastic rock of Xigaze forearc basin, is concordant on the Cuojiangding Gr. Four differences in sedimentology, stratigraphic palaeontology and structural geology show that there exists a nonconformity between Xigaze Gr and Cuojiangding Gr.Speaking concretely, this nonconformity existed between Qubeiya Fm.and Quxia Fm..The nonconformity was formed between Campanian maastrichtianand danian.The whole stratigrphic sequence of Xigaze forearc basin in this region reappear the course of strong underthrust between India plate and Eurasian plate fully.The main collision between India plate and Eurasian plate took place after “Rujiaozangbu psepholite” had been deposited, the time of collision between the two plates is later than primary understandings.??

Abstract：In western Qaidam basin, abundant Tertiary lacustrain stromatolites have been discovered recently in several kilometers Miocene strata from lower member of lower Ganchaigou Formation to lower Youshashan Formation in Ganchaigou area.The stromatolites, greatly variable in type and genesis, may partly reflect the Precambrian analogues and further be in contrast with the modern stromatolites, therefore it is of important significance for the international stromatolite research.According to the recent study and trend, the stromatolites in western Qaidam basin may be classified as skeleton, agglutinated and fine?grained types which also imply different genesis.The skeleton stromatolites is formed through microbially biological mineralization and calcification combined with in-situ precipitation; the agglutinated stromatolites are mainly related with binding and trapping performed by prokaryotic and eukaryotic algae together; and the fine?grained stroamtolites are mainly formed through biofilm calcification, over?saturated calcite precipitation on the biofilm and microbial chalk precipitation Overall, the frequently fluctuated lacustrine conditions and the surrounding tectogenesis are mainly responsible for the greatly varied form, different genesis of stromatolites.The detailed discussion and study on Qaidam examples will offer valuable modern analogues in the research of sedimentology and environmental science.

Abstract：Although Qinling lead zinc ores belt related to hydrothermal sedimentary, Zhashan area has more special copper metallogenic background than that of Fengtai area— geological setting, basal of basis.On the basis of fluid inclusions of the Mujiazhuang copper deposit, it is showed that there were two stages of fluid evolution. The first stage is magma hydrothermal with middle temperature, middle and high salinity(CO2)H2O,NaCl fluid, which homogenization temperature are 190~265oC and salinity 12.5~35.34(wt%NaCl),pressure 12.8~21.3MPa.Meanwhile, a large of three facies fluid inclusions with a salty crystal coexistence to vapour faices inclusions are discovered in the high and middle high temperature steps of homotemperature of fluid inclusions for the Mujiazhuang copper deposit. It is suggested that the mineralization fluid is over-saturation and occurring boilization and supposed that there is magmachamber in deep of mining area.The second stage is behind hydrothermal of magma with middle?high temperature, middle and high salinityH2O NaCl fluid,
which homogenization temperature are 300~350oC and salty 7.4~41.59(wt?%NaCl),pressure 10.8~19.3MPa.Boilization is an important mechanism of mineral matters precipitation?On the basis of Geochemistry of fluid inclusion(fluid composition, fluid evolution), it is approved that the mineralization fluid is from
the magma water in the Mujiazhuang(the first stage), and is from the formational
water and the deep?derived magma in the Mujiazhuang (the second stage).In ad
dition, the hydrogen and oxygen isotopic data of the Mujiazhuang copper deposit
