    内蒙古东南部孔兹岩系进变质过程矿物组合演化——来自锆石中矿物包裹体的证据

    • 摘要: 采用激光拉曼技术,确认内蒙古中南部孔兹岩系锆石中保存进变质阶段矿物组合蓝晶石 钾长石 石英 磷灰石,蓝晶石 石榴石 钾长石 石英;峰期阶段矿物组合夕线石 石榴石 钾长石 石英,夕线石 石榴石 钾长石 石英 磷灰石。表明孔兹岩系在变质过程中矿物组合及相应的PT轨迹经历了自蓝晶石稳定区向夕线石稳定区的转变。

       

      Abstract: Inclusions of the kyanite K-feldspar quartz apatite and kyanite garnet K-feldspar quartz assem-blages of the prograde metamorphic stage and the sillimanite garnet K-feldspar quartz and sillimanite gar-net K-feldspar quartz apatite assemblages of the peak metamorphic stage were identified by laser Raman spectroscopy in zircons from the khondalite series in south-central Inner Mongolia.These data indicate that the mineral assemblages and P-T path of khondalites series experienced transformation from the kyanite sta-bility field to sillimanite stability field.
