煤是一种对温度、压力等地质环境因素特别敏感的有机岩。煤化作用实质上是煤与外界进行能量和物质交换的一个开放系统。地质历史演化过程中的各种构造-热事件必然导致煤发生一系列物理、化学、结构和构造变化,煤中有机组分和无机组分在各种地质营力作用下迁移、分异和改造,从而影响煤层现今赋存状况、煤化程度和煤质特征,在一定程度上记录了沉积盆地动力学过程的地质信息。文中介绍了国内外在煤化作用与构造-热事件的耦合效应方面的研究进展,讨论了存在的问题,提出了重点研究课题。
Coal is a type of organic rock that is particularly sensitive to geological and environmental factors such as temperature and pressure. Coalification is essentially an open system of coal and energy and material exchange with the outside world. Geological history of the evolution of the various structures - thermal events will inevitably lead to a series of coal occurrence of physical, chemical, structural and structural changes in the organic and inorganic components of coal in a variety of geological forces migration, differentiation and transformation , Thus affecting the current occurrence of coal seams, coalification and coal quality characteristics, to a certain extent, recorded the sedimentary basin dynamic process of geological information. In this paper, the research progress of the coupling effect between coalification and tectonic-thermal events at home and abroad is introduced, the existing problems are discussed and the key research topics are put forward.
