Abstract: According to a series of domestic and foreign reference materials, the paper summarizes the properties of coal quality for magmatic thermo-metamorphism; coal zonal distribution regularity; and the genesis indication for magmatic thermo-metamorphism. Moreover, the paper emphatically analyse the formative mechanism on magmatic thermo-metamorphism, The author points out new type of geological pattern for magmatic thermo-metamorphism, it may be described as follows, heater （magmatic）-heat collecting system-geothermally disturbed area- coal metamorphic zones, this viewpoint especially emphasizes the interrelation between heater （magmatic） and geologic boundary condition, and make sure is an important reason for causing coal metamorphic difference.
