中国含煤岩系构造变形控制因素探讨

Study on Control Factors of Deformation of Coal Measures in China

后期构造变形及其变形特征的时空差异是中国含煤岩系赋存状况的一个显著特点．造成这种特殊煤田地质条件的控制因素主要包括地球动力学环境、构造演化进程、深部构造与基底属性、构造应力场作用、煤系和上覆下伏岩性组合等５个方面．

The main control factors of coal measures deformation and coalfield tectonic framework in China are studied, which include geodynamic environment, tectonic evolution, deep structure and basement property, tectonic stress fields, lithologic association within coal measure and adjacent strata series. The outstanding characteristics of coal measures distribution in China is its structural deformation and deformed difference in time and space, the deformation of coal measures in China can be divided into three parts: the NE SW trending deformation area of eastern part made of extension subregion in North China and superimposed deformation in Southeast China, the NW SE trending deformation area of western part made of positive inversion subregion in Northwest China and compress subregion in Southwest China, and the stable area of middle transition part.
