| 摘 要： | According to the evolution of alkali elements (e.g. K, Na, Li) and the relationship among them in the melt-solution of pegmatitic magma the author has divided the pegmatitic process of the vein No. 3 into three main geochemical stages associated with mineralization, i.v. K-Na, Na-Li and K stages. The above division scheme has been proved to be valid by field geological survey and the laboratory data on ther modynamic analyses. Additionally, .the related thermodynamic analyses are given herein on (1) the albitization of microcline formed at the earliest stage, (2) the hydrolysis of mierocline (greisenization), and (3) the formation and stability of spodumenes.
