断层附近反牵引现象的研究

断层附近的反牵引现象是正确判断断层性质，准确寻找断失煤层的一项非常重要的干扰因素，笔者认为，一期构造力形成的正确层国的反牵引褶曲与递断层上升盘牵引褶曲在形态上的区别是，前者是沿断面向下滑的，褶曲较开阔，不形成岩层倒转；后者除断层倾向岩层倾向相反时外，是沿断层面向上推的，褶曲较紧闭，且经常形成岩层倒转，两期构造力复合形成的正断层的反牵引现象，前期由挤压力形成递断层附近的牵引褶曲；后期由拉伸力使两盘沿断面产生相对的升降，断层落差后期大于前期。

Study on the Phenomena of Reversed Folds Nearby Faults

The phenomena of reverse folds nearby fault is a very important interfection factor by which to Judge faulted character and search for lost ledge coal bed. The author thinks that difference of shape between reversed folds of falling bulks of centripetal faults and folds of ring bulks of centrifugal faults lies in the fact that the former slides down along fault surface, showing wide open folds and forming no rock reverse while the latter pushes up along fault surface, showing tight folds and forming rock reverse.The phenomena of reversed folds of centripetal faults stemming from two-phase tectonic stress shows that drag folds nearby centrifugal fault is formed by pressing during the earlier stage and the relative motion up and down is formed by drawing force during the later stage. The fall of later stage is larger than that of the former stage.
