1超高压变质作用过程中的流体岩石相互作用——中国大陆科学钻探工程主孔(0~2050m)岩心的氧同位素证据显示文摘中国大陆科学钻探工程主孔位于苏鲁超高压变质带南部的东海地区。该钻孔 0~ 2 0 5 0m井段钻遇的岩石主要是榴辉岩、正片麻岩、副片麻岩和石榴石橄榄岩。激光原位氧同位素研究表明 ,变质矿物的δ18O值具有显著的不均一性 ,从 - 6 .8‰变化至 + 7.5‰。空间上看 ,从近地表至 10 0 0m深度δ18O值逐渐降低 ,向更深处又逐渐升高。位于钻孔 110 0~ 16 0 0m深度之间的正片麻岩是新元古代花岗岩体 ,该岩体的侵入为表壳岩与低氧同位素大气降水之间的水岩交换作用提供了热源 ,并导致岩体附近的围岩发生了最强烈的水岩蚀变 ,因此具有极低的氧同位素值。研究还显示 ,在厘米尺度内 ,大多数超高压变质矿物之间具有平衡的氧同位素组成 ,所获得的超高压峰期变质温度为 70 0~ 882℃ ,与矿物之间的主元素交换温度计获得的结果基本相同。超高压变形与变质分异、高压退变质作用及其伴生的局部流体活动可能是造成超高压变质矿物氧同位素不平衡的主要原因。研究进一步证明 ,超高压变质岩原岩的异常低氧同位素特征在大陆板块的俯冲与折返过程中得以较好保存 ,在超高压变质前期、同期和后期均没有大规模的透入性流体活动发生。与围岩呈构造接触关系的石榴石橄榄岩具有正常地幔岩的氧同位素成分 。张泽明 肖益林 Jochen HOEFS 高勇军 2004岩石矿物学杂志2004,23,4:6

16Niobium-tantalum Fractionation During Slab Subduction:Implications for the Formation of Continental Crust显示文摘 Compared with the oceanic crust, knowledge about the formation of the continental crust (CC) is relatively poor. Although melting of subducted slabs in the early history of the Earth has been considered as the major way that shaped the chemical characteristics of the CC by most geologists, as the CC shares many characteristics with modern adakites, some geologists argued that Archean TTG was formed in the same way as modern arcs rather than slab melting, whereas others proposed that melting at the bottom of the thickened oceanic crust was more important. Recently,the debate is mainly focused on the unique subchondritic Nb/Ta value of the CC, and particularly, how Nb and Ta fractionated from each other and consequently how, in detail, the CC was built.……Yilin Xiao Weidong Sun Jochen Hoefs Klaus Simon Zeming Zhang Shuguang Li Albrecht W.

17Li and B Isotope Systematics of Ultrahigh-pressure Metamorphic Rocks from the Chinese Continental Scientific Drilling Program显示文摘 1 Introduction Recent improvements in the precision of Li and B isotope measurements have demonstrated the potential of these elements in tracing a wide range of geological processes. The Li and B isotope systematics of ultrahigh-pressure (UHP) metamorphic rocks provides a unique opportunity to investigate the behaviour of Li and B during fluid-rock interaction at high temperatures and very high pressures and to constrain the fluid budget and the recycling of subducted crustal materials into the mantle during UHP metamorphism. ……Yilin Xiao Rolf L.

18Laserprobe oxygen isotope analysis of minerals from mantle-derived rocks in eastern China显示文摘Oxygen isotope analyses were carried out by the laserprobe technique for mineral separates from mantle xenolith and megacryst in Cenozoic basalts, East China. The results not only give the δ I8O range consistent with that reported for peridotites in the world, but also yield oxygen isotope equilibrium between coexisting minerals.Yiliang Li Wiechert Uwe Yongfei Zheng Xiachen Zhi Jochen Hoefs 1999Chinese Science Bulletin1999,44,8:0
