摘要
运用地质力学观点,分析研究燕山期发育于黔西地区的正、反扭动构造的特征、成因及其复合叠加规律,并认为它们是黔西煤田后期改造的主要控制构造,是欧亚板块、太平洋板块和印度洋板块相对运动的结果。此外,黔西地区还有经向构造和纬向构造,上述四种构造是黔西的基本构造,至于其它构造形式,笔者认为它们是上述四种基本构造运动发展不同阶段、次级派生的和四种基本构造运动相互复合、联合的产物。
In this paper, it used the geomechanics theory to study the characters, causation and its composite superposed regulation of pro and con wrench structures in the west Guizhou where stage of Yanshan developed. It＇ s the result of relative movement of the Eurasian plate, the Pacific plate and the Indian plate. In addition, there are east -west and south -north structures, the above four structures are the basic structure in west Guizhou. For the others, it＇s thought that they are the outcomes of the basic tectonic movements in different stages, secondary derivation and by mutual recombination and association.
