中文摘要：

一个连续流动方法，由热变换的联合有同位素比率团 spectrometry (MS ) 的元素的分析器(TC/EA ) ，被开发决定两篇 H 同位素作文和 H2O 集中超离频压力(UHP ) 在 Dabie-Sulu orogenic 的变形岩石系上带子。由使用发达加热步的技术，我们学习了 H2O 集中和水的不同形式的 H 同位素作文(结构哦并且分子的 H2O ) 在里面石榴石。H2O 集中的量的大小和在从几个典型露头的 UHP 变形岩石中的矿物质的 H 同位素作文显示片麻岩能在发掘期间比 eclogites 释放水的更多的数量深深地 subducted 大陆人外壳。由在在 eclogite 和片麻岩之间的接触的解压缩脱水，因此，释放的水能在邻近片麻岩的 eclogite 的重要水和从片麻岩流动到 eclogite 和结果。在 eclogites 的矿物质的测量的最大的水内容显示分别地，那石榴石和 omphacite 在山峰 UHP 变形条件下面有 2500 和 3500 ppm 的最大的水溶解度。

英文摘要：

A continuous flow method, by a combination of thermal conversion elemental analyzer （TC/EA） with isotope ratio mass spec- trometry （MS）, was developed to determine both H isotope composition and H2O concentration of ultrahigh-pressure （UHP） metamorphic rocks in the Dabie-Sulu orogenic belt. By using the developed step-heating technique, we have studied H2O concen- tration and H isotope composition of the different forms of water （structural OH and molecular H2O） in garnet. The quantitative measurements of HzO concentration and H isotope composition of minerals in UHP metamorphic rocks from several typical out- crops indicate that the gneisses can release more amounts of water than the eclogites during exhumation of the deeply subducted continental crust. Therefore, by decompression dehydration at the contact between eclogite and gneiss, the released water could flow from the gneiss to the eclogite and result in significant hydration of the eclogite adjacent to the gneiss. The measured maxi- mum water contents of minerals in eclogites indicate that garnet and omphacite have the maximum water solubilities of 2500 and 3500 ppm, respectively, under the peak UHP metamorphic conditions.
