构造煤的动力变质作用及其演化规津

TECTONIC COAL DYNA MOMETAMORPHISM AND EVOLUTIONARY PROCESS

摘要: 采用X射线衍射分析、电子顺磁共振等方法研究了构造煤的动力变质作用特征和演化规律。构造煤与煤层的变形变质历史有关,动力变质作用形成的构造煤,其结构特征与其它变质类型煤不同,演化途径也不同,但它们的演化规律一致。

Abstract: Dynamic metamorphous features and evolutionary process of tectonic coal have been studied by X-ray diffraction and electron spin resonance (ESR). Tectonic coal is related to the evolutionary history of deformation and coalification of coal seam. Tectonic coal in structure is defferent with other metamorphous types of coal, their evolutionary process is same，but their developing way is not same.
