煤的岩浆热变质作用

根据国内外资料,概括总结了岩浆热变质作用的煤质特征、煤牌号带状分布的规律,以及岩浆热变质作用的成因标志。此外,还重点探讨岩浆热变质作用的形成机理,提出了一个新的岩浆热变质作用的地质模式,即热源（岩浆）-储热体系-地热异常区-煤的变质带。这一观点特别强调热源（岩浆）与地质边界条件的相互关系,并认为此乃造成煤变质差异的重要原因。 

MAGMATIC THERMO-METAMORPHISM OF COAL

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.
