贺兰山北段孔兹岩系中最有代表性的两类岩石：变粒岩及富铝片麻岩天然块状样品的脱水熔融实验研究表明，在变质反应过程中岩石的水逸度、氧逸度和氢逸度发生有规律的变化，而这种变化与含水矿物参与熔融的机理紧密相关，并决定岩石熔融的程度、成分和熔融机制。他们之间演化规律的研究，对于阐明混合岩化作用与岩浆作用之间的关系和演化均有重要的意义。
The two representative rocks in the Khondzi department of northern Helan Mountain are dehydrated and melted in natural massive samples of granulite and aluminum-rich gneiss. The results show that the waterfluidity, Degree and hydrogen fugacity change regularly, and this change is closely related to the mechanism by which water-bearing minerals participate in melting and determines the extent, composition and melting mechanism of rock melting. The study of the evolution between them has important significance in elucidating the relationship between the migmatitic and magmatism.
