本文提出混合岩化作用是指地壳深部的深熔作用,在地壳褶皱带中引起一般岩石的深熔和分异;再由熔融物质侵入到地壳上部,与围岩发生混合和交代所成。混合岩化的全过程都按矿物组合的反应式,分为两个不同阶段表示出来。这样的混合岩化演变过程,可能在地壳褶皱带中是一般岩石变化的普遍规律。本文并证明了混合岩化作用的矿物组合变化范围和形成的温度、压力,最后讨论混合岩化的原岩问题。
In this paper, we suggest that the mixed rockification is the deep melting of the deep crust and causes deep melting and differentiation of common rocks in the crustal fold belt. Then the molten material intrudes into the upper part of the crust and is mixed and confused with the surrounding rock. The whole process of mixed rockification is based on the reaction of mineral assemblage, which is divided into two different stages. Such a process of mixed rock evolution may be a common law of general rock changes in the crustal fold belt. This paper also proves the scope of the mineral assemblage change and the temperature and pressure of formation, and finally discusses the problem of the protolith of mixed rock formation.
