Abstract On the basis of field investigation, the quartz particles in three gouge samples collected from Xuancheng-Jingting mountain section of Jiangnan fault zone, are observed and counted by transmission scanning electron microscopy(SEM). The results show that Jiangnan fault zone is an active fault zone, which has obvious activity in the Neogene and Quaternary. The activity began in the Miocene and reached its peak in the late Pleistocene. The main mode of activity is creep slip. In the Holocene, the faults continue to move in the way of stick slip. Seismic records along the fault show that the fault is still active until modern times. This conclusion is of great significance for correctly evaluating the Quaternary movement of the Jiangnan fault zone and preventing natural disasters in this area.
