| 摘 要： | 片岩—石英岩型蓝晶石矿床的成矿原岩是富铝粘土质砂岩。矿床的形成经历了三个主要的成矿阶段,即高绿片岩相区域变质成矿作用、动力变质成矿作用及气成热液成矿作用。它们在矿物组合、岩石常量化学成分、岩石微量及稀土元素地球化学、成矿的温压条件及矿物学特征等方面存在一定的差异。

| Abstract: | Ore-forming protolith of schist-quartzite type kyanite deposits is Al-rich clayey sandstone.The formation of the deposits underwent three ore-forming stages,i.e. high-grade greenschist facies regional metamorphic mineralization,dynamic metamorphic mineralization and pneumatolyto-hydrothermal mineralization,which show certain differences in mineral association,chemical compositioh of bulk elements,geochemistry of microelements and REE,temperature and pressure conditions of mineralization and mineralogical character istics and so on. |
