二组分固-液平衡相图在矿物结晶中的应用

Application of Binary Solid-Liquid Equilibrium Phase Diagram in Mineral Crystallization

主要介绍了二组分固–液平衡相图在岩浆形成矿物过程中的应用,列举了简单低共熔、有化合物生成和有固溶体生成的三种类型的固–液平衡相图应用实例,最后分析解释复杂相图,为提高学生对基础相图知识掌握和运用能力提供素材。

We mainly introduced the application of binary solid-liquid phase diagram in the process of magmatic mineralization.Three kinds of equilibrium phase diagram:eutectic phase diagrams,phase diagram with the compound formation,and solid solution phase diagram was descriped.Then,complex phase diagram were analyzed.This paper can provide learning cases to improve geoscience students'ability of analyzing problems.
