| 1 | 南天山:晚古生代还是三叠纪碰撞造山带?显示文摘伊犁-哈萨克斯坦板块和塔里木-卡拉库姆板块之间的南天山造山带是‘中亚型造山带’的典型代表之一,经历了复杂的构造演化与地壳增生过程。传统上,它被视为华力西期褶皱带或晚古生代碰撞造山带。但近年来,部分学者提出它可能为三叠纪碰撞造山带。本文在综述南天山造山带的蛇绿岩、高压变质岩、花岗岩类等方面研究成果的基础上,讨论了其碰撞造山的时限。我国境内南天山西段碰撞造山可能开始于早石炭世(345Ma),结束于晚石炭世末(300Ma左右)。二叠纪时期,南天山至整个中亚地区进入后碰撞演化阶段。现有资料证实南天山为一晚古生代碰撞造山带,并非一三叠纪碰撞造山带。 | 高俊 龙灵利 钱青 黄德志 苏文 Reiner KLEMD | 2006 | 岩石学报2006，22，5： | 226 |
| 2 | 那拉提山北缘寒武纪玄武岩的元素地球化学特征及构造意义显示文摘我国西南天山地区那拉提北缘断裂北侧出露寒武纪(516.3±7.4Ma)橄榄拉斑玄武岩,其 Al_2O_3(12.71%~14.14%)、P_2O_5(0.09%~0.21%)含量较低,TiO_2(1.39%~2.35%)、MgO(5.35%~8.14%)含量中等,全 Fe_2O_3(11.74%~16.03%)含量较高,球粒陨石标准化稀土分布型式平坦,(La/Sm)_N 和(Y/Nb)_N 比值接近1,为过渡型洋脊玄武岩(T-MORB);并且 Th/Ta 比值(0.8~1.5)低,高场强元素(Nb,Ta,Zr,Hf,P)没有明显亏损,缺乏陆壳混染或俯冲带流体活动的印迹。部分 T-MORB 的 Fe、Ti 含量较高(FeO^T>12%,TiO_2>2%,FeO^T/MgO>1.75),Mg~#值(0.40—0.49)和 Cr(53×10^(-6)~110×10^(-6))含量较低,属于 Fe-Ti 玄武岩(ferrobasalt),应为岩浆依 Fenner 趋势发生较高程度结晶分离演化的产物,很可能形成于洋中脊的扩展型裂谷环境。我们认为,那拉提北缘寒武纪 T-MORB 和 Fe-Ti 玄武岩可能与境外吉尔吉斯斯坦境内北天山南缘的早古生代 Terskey 蛇绿岩带相连,为 Terskey 蛇绿岩的残片;寒武纪我国境内发育 Terskey 洋。那拉提北缘断裂可能与尼古拉耶夫线相连,代表西南天山地区 Terskey 洋闭合形成的一条早古生代缝合带。 | 钱青 徐守礼 何国琦 Reiner KLEMD 熊贤明 龙灵利 高俊 | 2007 | 岩石学报2007，23，7： | 24 |
| 3 | Origin of the deep fluids in the paleosubduction zones in western Tianshan:Evidence from Pb-and Sr-isotope compositions of high-pressure veins and host rocks显示文摘Fluids in the deep subduction zones play an important role in crust-mantle ex-change related to the subduction process. Identification of fluids origin, internal or external, can help us to evaluate the contribution of crust materials to mantle during this process. High-pressure veins, which developed in the western Tianshan HP-metamorphic belt extensively, are the direct products of the fluids in subduction zones. In western Tianshan, high-pressure veins and host rocks have overall Pb- and Sr-isotope compositions. At t = 340 Ma, the high-pressure metamorphic time, the ratios of 206Pb/204Pb, 207Pb/204Pb, 208Pb/204Pb and 87Sr/86Sr of high pressure veins are 17.122―18.431, 15.477―15.611, 37.432―38.689 and 0.70529―0.70705, and are 17.605―17.834, 15.508―15.564, 37.080―38.145 and 0.70522―0.70685 for host rocks. However, high-pressure veins show a much larger variation in Pb-isotope composi-tions than host rocks. Plots of samples are distributed roughly along a line parallel to and far away from the Northern Hemisphere reference line (NHRL) on the plot of 206Pb/204Pb vs 207Pb/204Pb. On the plot of 206Pb/204Pb vs 208Pb/204Pb, plots of data are distributed nearby mid-ocean-ridge basalts (MORB) area or along a line parallel to and not far away from NHRL, which shows that the data plots are farther away from MORB and ocean island basalts (OIB) areas on the plot of 206Pb/204Pb vs 207Pb/204Pb than on the plot of 206Pb/204Pb vs 208Pb/204Pb. The compositions of Pb- and Sr-isotopes of these high-pressure metamorphic rocks are between that of enriched mantle 1(EMI) and of sediments or upper crust. A notable characteristic can be seen from plots of Pb-isotope ratio vs Pb-isotope ratio and 206Pb/204Pb vs 87Sr/86Sr that array of plots shows an evident tendency of mixture of two end members. Ratios of Rb/Ba, Ce/Pb, Nb/U and Ta/U of high-pressure veins and host rocks are between that of OIB or MORB and that of conti-nental crust, which indicates that continental crust materials probably have been incorporated into the rocks. The fluids in the paleosubduction zones in western Tianshan are mixtures of two sources, one originating from the devolatilzation of the host rocks with protolithes similar to ocean basalts from enriched mantle 1 (EMI), the other from the dehydration of subducted sediments. | Reiner Klemd | 2005 | Science China Earth Sciences2005，48，10： | 6 |
| 4 | 俯冲板片中微量元素的活动性:西天山榴辉岩相运输脉的制约显示文摘西天山的基性高压变质岩显示互相连接的榴辉岩相脉体网络来源于蓝片岩的进变质脱水作用,通过这些网脉可以洞察在俯冲带高压条件下远程流体流动中的流体一岩石相互作用和元素负载。岩相学证据表明外来流体的渗透作用产生运输脉,而流体持续的沟道式流动导致主岩蓝片岩的淋滤。脉和蓝片岩蚀变带中锂(Li)的含量几乎是蓝片岩主岩中锂的两倍,它支持流体是外部来源的设想。这些流体触发了蓝片岩主岩的榴辉岩化作用而形成蓝片岩蚀变带。由于成脉流体中的微量元素含量低,所以导致与流体发生化学反应的主岩中所有微量元素的强烈淋滤。在此过程中有53%~81%的微量元素被活化,与大离子亲石元素和轻稀土元素的损失相符合,它们的损失量几乎是重稀土元素和高场强元素损失量的两倍。 | 熊贤明 Timm JOHN 高俊 Reiner KLEMD 黄德志 | 2006 | 地质学报2006，80，1： | 6 |
| 5 | 俯冲洋岛玄武岩脱水释放的水流体成分:来自西天山榴辉岩相高压脉的约束显示文摘俯冲洋壳的脱水作用对于岛弧火山岩的成因具有重要意义。西天山高压低温变质带中切割主岩蓝片岩/榴辉岩的榴辉岩相脉体记录了古生代俯冲带中的脱水过程。脉体具有典型高压矿物组合:石榴石(>8%)+绿辉石(15%)+石英(>55%)+蓝闪石(5%)+冻蓝闪石(10%)±黝帘石±方解石。高压脉及其主岩的岩相学与矿物化学研究表明流体是在俯冲过程中蓝片岩向榴辉岩进变质条件下释放。脉的主量元素成分显示流体富Si。主岩的稀土元素和微量元素表明其原岩为洋岛玄武岩(OIB)。脉和主岩具有相似的微量元素配分模式,并且相对N-MORB都显示富Li、Be、Cs、Rb、Ba、Pb、La的特点。通过模拟计算,在高压脉、与脉平衡的流体以及模拟的原生流体中都富集流体活动性元素(Li、Be、Pb)和LILE(Cs、Rb、Ba),贫HFSE(Nb)和REE(Nd、Sm)。证实了在古生代南天山洋俯冲时洋岛玄武岩脱水释放出富Li、Be、LILE、La和Pb,贫HFSE和HREE的流体。 | 熊贤明 高俊 Reiner KLEMD 黄德志 | 2006 | 岩石学报2006，22，1： | 5 |
| 6 | 西天山高压脉及主岩的氧同位素研究——古俯冲带深部流体及俯冲特征的启示显示文摘位于中国南天山的西天山高压变质带代表了伊犁-中天山与塔里木两个板块间古生代南天山洋的古俯冲混杂岩带。高压变质带内广泛发育高压脉。为探讨古俯冲深部流体来源及运移特点及板块俯冲特征,对高压脉和主岩的全岩及主要的高压变质矿物的氧同位素进行了分析。高压脉的δ^18O值变化于+8.28‰与+10.70‰之间,多数在+9.50‰±1范围内。基性变质岩的主岩与高压脉具相似的氧同位素组成,变化于+9.25‰~+10.10‰之间。高压脉和主岩的全岩δ^18O值变化不大。高压脉与相邻主岩间、同一高压脉中间与边部间氧同位素组成的变化没有明显的规律,一般变化不大,对于大多数脉-主岩对,变化小于1‰。与全岩完全不同的是,单矿物氧同位素组成显示出很大的变化范围,石英、石榴石、绿辉石的δ^18O值分别为+11.40‰~+15.20‰,+3.59‰-+11.60‰和+8.30‰~+13.05‰,多硅白云母和蓝闪石δ^18O的变化较小,分别为+10.00‰~+11.10‰和+9.26‰-+9.94‰。榴辉质岩石中高压变质矿物间氧同位素分馏广泛不平衡。全岩氧同位素组成特征表明,俯冲带深部流体主体来自邻近主岩,外来流体对氧同位素贡献有限。单矿物氧同位素广泛不平衡特征可能指示古俯冲带俯冲板片的快速俯冲和折返以及部分外来流体的参与。 | 黄德志 高俊 张进富 张德贤 戴塔根 Reiner KLEMD | 2006 | 岩石学报2006，22，1： | 3 |
| 7 | 西天山榴辉岩石榴石中的水及其分布特征显示文摘运用电子探针和显微Fourier变换红外光谱技术,对新疆西天山3个榴辉岩样品中的石榴石进行了详细的主量元素和结构水分析。结果显示,石榴石发育以核部富锰铝榴石组分、边部富镁铝榴石组分进变质作用的成分环带。石榴石中OH^(-1)分布也具有规律:核部→边缘,其结构水OH^(-1)逐步增加,即从核部的89~239ppm增加到边部的367~658ppm;与石榴石边部相比,石榴石的核部含有较低的OH^(-1),却含有较高的H_2O和Mn含量。这表明,在蓝片岩向榴辉岩进变质作用过程中,含水矿物脱水反应而释放出大量的分子水,这部分水促进了高压变质反应,形成榴辉岩相矿物,石榴石核部的结晶就是在富水和Mn的条件下进行的。随着高压变质作用的继续,石榴石核部的分子水逐步失水而进入石榴石晶格,形成结构水。因此,在高压变质作用过程中,OH^(-1)演化实际上是一个由内部不平衡逐步向平衡转变过程。 | 苏文 高俊 Reiner KLEMD 熊贤明 | 2006 | 岩石学报2006，22，5： | 2 |
