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.

摘要： 活断层产物的研究近年来受到国内外地震地质学者的关注。笔者对地质、地震证据充分的活断层--红河断裂带和曲江断裂带的断层泥进行多种手段的分析研究。它们的显微构造、粒度分布,组构特征以及石英碎砾的SEM显微形貌等显示了活断层中的长期蠕滑研磨作用、地震过程的快速剪切运动以及活断层特定条件下的退变质作用和其他化学作用等成因特征。综合分析指出,红河断裂带南段可能是蠕滑运动为主的活断层,其北段和曲江断裂带则为粘滑运动为主的活断层。
