| 摘 要： | 断层泥是断层活动的信息载体,其中的石英颗粒微形貌特征能够反映断层活动年代、活动方式。利用扫描电镜,对云南龙陵县黄草坝附近,断裂带中断层泥石英样品进行了表面溶蚀微形貌特征的观察统计及应力痕迹微形貌观察。结果表明黄草坝断层最新活动时代为全新世早期,且活动方式以粘滑为主。 |
| 关 键 词： | 活动断裂 断层泥 石英形貌特征 |

| Abstract: | Gouge is an information carrier for fault activity, and the motion mode and date of the fault activity can be identified by observation of micro-shape characteristics of quartz in the gouges. In this paper, dissolved micro-shape and stress micro-shape of the quartz, which were collected from the gouge of the fault near Huangcaoba, Longlin, Yunnan, are observed and statistically analysed by SEM. The results show that Huangcaoba faults latest activities for the holocene early, and fault was dominated by stick slip. |
| Keywords: | activity fault fault gouge quartz morpholocal features |
