| 摘 要： | 电气石族矿物化学成分多样，同一位置类质同像替代多。电气石形成的温度压力范围很广，能够在地壳的温度压力范围内稳定存在，并且与多种地质流体保持平衡。电气石结构内主微量元素的扩散速率极低。电气石矿物硬度较大，形成后能够经受住剥蚀、风化、成岩和变质作用过程而保存其形成时的组成与结构。通过对组成电气石的主微量元素、稳定同位素（包括B、Li、Sr和Nd等）和放射性同位素（K-Ar、Ar-Ar等）的分析可以示踪电气石及其共生矿物形成时的成岩成矿环境，包括流体的来源、氧化还原状态、温度压力、形成时代及其在矿床勘探方面的指示意义等。

| Abstract: | Tourmaline mineral has various chemical composition and multi-isomorphism on the same position.Their formation temperature and pressure range is very extensive,can be stable in the temperature of the earth’s crust pressure range,and can keep balance with various geological fluid.The main and trace elements spread rate of tourmaline structure is extremely low.And tourmaline mineral hardness is bigger,after forming can withstand erosion,weathering,diagenesis,metamorphism process and save the composition and structure when they formed.Through analysis the trace elements,stable isotopes(including B,Li,Nd,etc),radioactive isotopes(K-Ar,Ar-Ar,etc) which composite tourmaline can tracer the diagenesis and mineralization environment,including the source of the fluid,redox condition,temperature and pressure,formation age and mineral instruction significance in the exploration. |
