摘　　要：描述了相山火山盆地北缘存在的3条北东向断裂构造,根据笔者在野外露头勘查、节理统计、构造剖面中获得的信息,结合区域构造背景分析了其运动学特征,认为这些北东向断裂构造为一系列产状、性质相似的走滑断层。该断层可能形成时代可追溯至加里东期,伴随在近南北向挤压区域应力场作用下产生,具有多期活动的特征。The north-east trend faults in the north part of Xiangshan volcano basin has been described in this paper.Based on detailed analysis on the existing regional structure and the results of previous studies,the feathers of the north-east trend faults have been studied through outcrop investigation and trench profiles,combined with the analysis of drilling data in recent years.It has been present in this paper that the north-east trend faults in north part Xiangshan volcano basin is a series of faults with similar feather,similar occurrence,strike-slip fault.The time of the formation of these faults can be traced back to the Caledonian.These faults may generate during the formation of the near north compressive stress and had experienced multi-stage tectonic activities.
