煤的变质类型有:区域(深成)、接触或热力和动力(错动或构造应力)三种。七十年代,随着断块学说在我国的兴起,应用断块构造的基本理论研究煤的变质规律问题就提出来了,内热(浅成)变质,就是应用断块学说研究华北断块石炭——二迭纪煤的变质过程中逐渐认识的,并将继续探索。 一、基本概念 断块学说的基本观点:从大陆地质构造的地质力学分析与地质历史分析相结合,断块学说与板块学说相结合,地质学与地球物理学相结合,动力学与运动学相结合。其实就是把空间和时间,垂直运动与水平运动,内因和外因相结合。煤的变质是由内因和外因两个因素造成。内因主要是指煤原始
Coal metamorphic types are: regional (deep into), contact or heat and power (dislocation or tectonic stress) three. In the seventies, with the rise of the fault block theory in our country, the application of the basic theory of fault block structure to study the metamorphic law of coal was proposed. The internal heat (superposition) metamorphism is the application of the fault block theory to study the carbon- - Permian coal metamorphic process gradually recognized, and will continue to explore. First, the basic concepts Block theory of the basic point of view: from the geological structure of the geological analysis of geology and geological history of the combination of theory, theory and theory of plate combination plate combination of geology and geophysics, kinematics and kinematics Combined. In fact, the space and time, vertical and horizontal movement, internal and external factors combined. Coal deterioration is caused by both internal and external factors. Internal causes mainly refers to the original coal
