中国煤种分布规律的探讨——煤变质区和煤变质区的类型

PROBING ABOUT THE DISTRIBUTION LAW OF COAL SORTS IN CHINA—Coal Metamorphism Region and Coal Metamor phism Region Types

本研究把煤变质作用和煤种分布问题放到区域大地构造的背景下加以研究,着重考虑不同地区成煤作用发生后的地质发展历史,特别是成煤后地壳活动的特点和此过程中地壳发展史中出现的热事件。在此基础上提出“煤变质区”的概念和类型,并对我国的“煤变质区”进行了具体的划分。

This paper studies the coal metamorphism and coal sort distribution problem in the background of the regional land structure centers on considering the geological development history after the incoalation occurrence in different region, especially the crustal movement characteritics after the incoalation and thermal event appeared during the crustal development history in the occurrence. On the basis of what is said above we put forward the concept and types of'Coal Metamorphism Region'and specifically divides the'Coal Metamorphism Region'in China.
