鲜水河断裂带是一条挽近活动强烈的断裂带,其地震活动甚为频繁,具有继承、发展、新生性、“三合一”(新、老构造形迹、地震地裂缝三者吻合)的特点,已引起广大地震工作者的关注。研究其控制性的先成构造格架及先成断裂系统的特征,对开展该区地震地质工作占居重要地位。为研究该断裂特征与地震活动、新老构造形迹间的相互关系等我们曾做了大量的工作,但由于鲜水河断裂形迹大部份地 The Xianshuihe fault zone is a strong active strike-slip fault zone. Its seismic activity is frequent and has inheritance, development and rejuvenation. The “three-in-one” (new and old tectonic trace and earthquake ground fissure match) Features, has aroused the concern of the majority of earthquake workers. Research its control of the preformed tectonic framework and the characteristics of a pre-fault system, to carry out the area of ​​seismic geological work occupies an important position. In order to study the relationship between this fault feature and seismic activity and the correlation between old and new tectonic features, we have done a lot of work. However, most of the fractures in Xianshuihe
