Abstract: The study of products from active fault has been concened by seismogeologists recently.Fault gouge from Honghe and Qujiang active fault zones has been studied.It is,shown that microstructure,grain size,fabric and SEM micro-surface texture on quartz fragment in gouge were formed during steady-state slip stage,rapid shear motion associated with earthquakes and retro-metamorphism and other chemical process in active fault zone.As the result of this study,the author pointed that the south segmetn of Honghe fault zone may be steady-state slip active fault,and the north segment of Honghe fault zone and Qujiang fault zone are stick slip active fault.
