| GEOLOGICAL CLASSIFICATION OF MIGMATIZATION |
| Migmatite and mechanism of migmatization have been controversial issues in the study of geology and petrology for the past so years. There are mainly two schools, namely, anatexis ultrametamorphis (Holmquest, Eskola and others) and palingenesis (Wegmann, Read et al), the latter emphasizing, the replacement of the "ichor".Since migmatization is a geological process and related to geological setting , it is subdivided into regional and local migmatizations. The former is closely connected with and is a developmental stage of regional metamorphi-sm, while the latter is not directly related regional metamorphism, but mainly associated with magmas in depth (either anataxitic or palingenetic megmas) and alkaline fluids. |
