岩浆-热液演化过程对成矿过程具有重要成因意义和科学研究价值,目前对这一过程的了解非常有限,因此备受关注和争议。完善分异的稀有金属伟晶岩通常经历了岩浆、岩浆-热液和热液三个阶段的演化,而目前对岩浆-热液过渡阶段性质尚不完全清楚,只是将其定性为"介于岩浆阶段和热液阶段之间的过渡阶段并以熔体相、晶体相和流体相共存为
The magmatic-hydrothermal evolution process has important genetic significance and scientific value for the mineralization process. At present, the understanding of this process is very limited, so it has received much attention and controversy. Permeable rare-earth pegmatite usually undergoes the evolution of magmatic, magmatic-hydrothermal and hydrothermal phases. However, the nature of the magmatic-hydrothermal transitional phase is not fully understood at present, During the transitional phase between the magmatic stage and the hydrothermal stage and with the coexistence of the melt phase, the crystal phase and the fluid phase
