Abstract Gouge is an information carrier for fault activity. The date of the fault activity can be identified by observation of the micro-morphologic characteristics of quartz in the gouges. In this paper, the dissolved micro-morphology of quartz, which are collected from the gouge of the Zhuying-Gongda fault belt in Sichuan Province, are observed and statistically analyzed by SEM. The result shows that the dissolved micro-morphology is not complicated. Comparing it with the diagram by Kanaori Y et al, it is indicated that the fault activity time was of Middle Pleistocene. This analysis is consistent with the dating value of the fault by ESR.
