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.
