在不同构造应力场中,多次活动的复合式断裂常常具有复杂的大学性质和多变的运动方式,历来是构造地质学中的一个难题.山东省某矿田的断裂,多数属于这种类型.作者采用宏观观察和显微构造分析相结合的方法研究这些断层,取得了较好的效果.应当指出,把显微构造分析方法应用于复合式断裂的研究是一种新的尝试.实践证明,它对宏观观察即起到一种验证作用又起到一种补充作用,这是一种值得提倡的科学研究方法. In many tectonic stress fields, the multi-active complex fractures, which are often characterized by complex nature and varied motions, have always been a problem in structural geology. Most of the fractures in a field in Shandong Province belong to this type The authors used macroscopic observation and microstructural analysis to study these faults and achieved good results.It should be pointed out that it is a new attempt to apply the method of microstructural analysis to composite fracture.It has been proved , Which plays a complementary role in macro observation, which is a kind of scientific research method worthy of promotion.
