摘要
本文从4个方面扼要地讨论了煤变质作用的近期进展。在煤级参数方面对镜质体反射率及其缺点和弥补的方法做了介绍,简述了近来提出的新的煤级参数。在煤化作用机理与特点方面概述了涉及煤化作用的煤结构研究新进展及其在煤化过程的演变中与镜质体反射率、挥发份的内在联系;煤化作用跃变与沥青化作用;“惰性组的煤化径迹”——煤化作用的一个新的方面。新的煤变质作用类型探讨。煤变质因素和煤化作用平衡,煤变质作用研究应用于其它地质学科。最后提出了应进一步研究的煤变质问题。
In this paper recent advances on coal metamorphism study are stated briefly. Part one
is about the vitrimte reflectance. especially the improvements to the deficiency of vitrimte
reflectance as a coal rank parameter, as well as the rank parameters newly suggested. Part
two is about the mecbanism and characteristics of coalification including: the study of coal
structure relating with coalification. the internal relations between coal structure and the
vitrinite reflectance and volatile matter during coalification. bituminization and coalifica-
tion jump. a new aspect of coalification-coalification track of inertinite. The other two
parts are sorne paoterns of coal metamorphism newly suggested besides the traditional
ones. and causes of metamorphism. coalification equilibrium and some examples of the ap-
plication of coal metamorphism study to geology. This paper is concluded with the prob-
lems need to do further works about coal metamorphism.
