Metamorphic processes are closely associated with the formation and evolution of the crust and highly related to petrogenesis and mineralization processes. Dynamic systematic analysis indicates that regional metamorphism-migmatization-metamorphic anatexis process is a temperature-pressure progressive process. Metamorphic anatexis process is a critical part with its unique pressure/temperature and thermodynamic, dynamic and geochemical characteristics. The concept of metamorphic anatexis system (MAS) introduced by the author includes the essential factors of material resources, energy resources, process format, material transportation and concentration, occurring time and location. Based on the essential factors of MAS, metamorphic anatexis process-related granitic rocks and deposit cases are discussed on their petrogenesis and/or mineralizaion mechanisms. The discussion points out that granites in the Ailaoshan and Yunkai metamorphic zones are of metamorphic anatexis origin. The genesis of pegmatite ore deposits in metamorphic zones and shear zone gold deposits in shear zones are highly related to metamorphic anatexis process. The study of metamorphism process involved in ore formation and material transport is a hot subject concerned by the international geological circles. Thorough investigations into the relationships between metamorphic anatexis and petrogenesis-meneralization processes are of great importance not only in geological theory, but also in industrial practice.
