| 摘 要： | 通过木里长枪构造-热穹隆体砂泥质变质岩及分泌石英脉中较系统的石英流体包裹体测试与研究,表明穹隆体中石英流体包裹体主要有NaCL-H2O、纯H2O及CO2-H2O、纯CO2等四类,有三个形成或捕获阶段,分别与穹隆体变形变质阶段吻合,其所限定的穹隆体变质条件及抬升P-T轨迹与变形-变质演化研究结果基本一致. |
| 关 键 词： | 石英流体包裹体 变质作用条件 抬升P-T轨迹 长枪穹隆 木里 |

| Abstract: | A study of fluid inclusions in quartz in sandy and pelitic metamorphic rocks and laterogenic quartz veins from the Changqiang thermal dome indicates that the fluid inclusions may be divided into 4 types such as NaCl- H2O type, pure H2O type, CO2 - H2O type and pure CO2 type which were trapped in 3 stages, coinciding with corresponding deformation- metamorphism stages, respectively. Metamorphic conditions and P - T locus for the dome body prescribed by them are consistent with the results of research on evolution of deformation and metamorphism of the dome body. |
| Keywords: | fluid inclusions in quartz metamorphic conditions P-T locus Changqiang thermal dome Muli |
