摘要
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。
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.
