利用显微Raman光谱,辨认了大别山超高压带片麻岩锆石中的矿物包裹体.作为钻石中包裹体,柯石英出现在所有类型的片麻岩中 其他重要的包裹体矿物还有硬玉、绿辉石、文石、重晶石和硬石膏等.这些发现表明:(1)榴辉岩与围岩片麻岩有同变质历史;(2)与柯石英共生的重晶石和硬石膏指示出超高压过程中有合SO2-4流体参与.
The mineral inclusions in zircons from the UHP gneiss in the Dabie Mountains were identified using microscopic Raman spectroscopy. As a diamond inclusion, coesite appears in all types of gneiss in other important inclusions minerals such as jadeite, omphacite, aragonite, barite and anhydrite. These findings indicate that: (1) eclogites have the same metamorphic history with the surrounding rock gneiss; (2) barite and anhydrite symbiotic with coesite indicate the presence of SO2-4 fluids in the UHP process.
