混合岩化带分布在古老地块边缘或地槽褶皱带内的正性活动带,其展布通常与区域构造带一致。混合岩在宏观上具塑性变形,微观上具构造岩特征,其稳定组分与活动组分的划分,以及各种交代现象等,也与构造岩相同。混合岩与绿片岩相—角闪岩相变质岩呈过渡关系,形成温度也大体相当,但远低于花岗质岩石重熔温度。作者认为,构造动力是混合岩形成的主因,并运用动力成岩成矿理论进行了初步地探讨。
The mixed rock belt is distributed in the positive edge of the ancient block or in the geosynclinal fold belt. Its distribution is generally consistent with the regional tectonic belts. The mafic rocks are macroscopically plastic-deformed, microscopically characterized by tectonic rocks, the division of the stable and active components, and the various metasomatism, as well as the tectonic rocks. The transitional relationship between the mixed rocks and the greenschist facies - amphibolite facies metamorphic rocks, and the formation temperature is also roughly the same, but much lower than the remelting temperature of the granitic rocks. The author believes that the tectonic motivation is the main cause of the formation of mixed rocks and the initial discussion is made by using the theory of dynamic diagenesis and mineralization.
