Abstract: The migmatization of the Mesozoic metamorphic zone along the coast of Fujian province is strong and rock types are complex, forming a complete, symmetrical intensity zoning which coincides with the framework of folds. In this paper, the authors deal with the basic characteristics of different types of migmatite with reference to petrology, mineralogy, metasomatic textures and REE geochemistry. On that basis three evolutionary series of migmatiza- tion are established. This paper discusses the features of changes in mineral composition, textures and structures and petrochemistry in the process of mig- matization of the rocks of various series. The granitic rocks widespread in the metamorphic zone may be classified into the zonal-marginal mixing type, the magma contamination type, the magma intrusion type, the volcanic intru- sion type. These granitic rocks have a close genetic relation to migmatite; they originated in different space and in different stages of the Mesozoic tec- tono-thermal cycle. It has been preliminarily ascertained that the migmati- zation of this zone possesses the characteristics of palingenetic migmatization. From a plate tectonic perspective, an attempt has been made to discuss the mechanism of migmatization.
