TECTONIC COAL DYNA MOMETAMORPHISM AND EVOLUTIONARY PROCESS
-
-
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.
