| 摘 要： | 通过高温高压实验，模拟了富氟花岗质熔体形成和演化的过程，结果表明，随着结晶分异作用的进行，熔体中SiO2含量降低而Al2O3和F含量升高，相应地，A／NKC和NKA／Si比值逐渐升高，并最终形成了贫硅过铝富氟的熔体。

| Abstract: | Through high T-P experiments, the process of generation and evolution of F-rich granitic melt had been studied. The results demonstrate that along with crystallization of granitic magma, SiO2 in the residual melt decrease, while Al2O3 and F increase which results in both A/NKC and NKA/Si rations to be increased, and finally poor-Si peraluminous F-rich granite melt to be formed. This is in good agreement with vertical petrochemical zonation observed in natural Li-F-rich granites. |
