这些特征表明层状混合岩是变质围岩经选择重熔交代而形成的。
So the results indicated that the layered migmatites are produced by anatexis and metasomatism of metamorphic wall-rocks.
变质交代过程中产生的再生锆石又可分早、晚两个世代。
Palingenetic zircon produced during the process of metasomatism can be divided into two generations: early and late.
变质型又可分为区域动力变质和接触变质交代两个亚型。
The metamorphic type can be further divided into two subtypes as regional dynamometamorphic and contact metamorphic ones.
