| 摘 要： | 通过对阜平群夕线石浅粒岩样品中黑云母的微形貌及其主要组成元素变化规律的电子显微镜研究 ,并结合浅粒岩和黑云变粒岩高温高压熔融实验研究结果的对比分析 ,获得了黑云母受深熔作用影响的微区信息。依据微形貌特征分为残留黑云母、不均一熔融黑云母和再结晶黑云母。深熔作用过程中Mg、Fe、Ti、K、Ca等元素从黑云母晶格中迁出 ,重组形成再结晶黑云母、磁铁矿、金红石、氟硅钠钾石类矿物

| Abstract: | It is shown that the micro-area information on the morphology and the change of main component elements in biotite have been made from study of natural sillimanite leuco-granulitite of Fuping group in Pingshan by SEM and compared with the high pressure and high temperature experiment of melting of leuco-granulitite and biotite granulitite. Biotite is divided into three types of the relic, nonhomogenized and melting recrystallized on the morphology. The elements of Mg,Fe,Ti,K and Ca are moved out from biotite lattice with anatexis and forming recrystallized biotite, magnetite, rutile, malladrite-hieratite. |
