magmametamorphism

According to a series of characteristics, such as X diffraction data, temperature test of inclusions, distribution of hydrothermal ore spots and coal quality parameters, it can be proved that magmatic thermal metamorphism which can be divided into telemagmat.

根据Ｘ射线衍射分析、包体测温、热液矿点的分布以及煤质参数等特征可以证明，除了深成变质作用外，岩浆热变质作用是该区主要的煤变质作用类型。
