| 摘 要： | 多期活动断层是经过多个构造旋回、多期变形的产物，它往往控制沉积盆地形成演化、岩浆活动及矿产分布，因此，在区调中加强对其调查与研究具有重要意义.以往在区调中，仅侧重于多期活动断层的最晚期或位移量最大一期活动性质的描述，图面上也只表示一期活动，所反映地质信息单一，不能表示断层多期活动及演化的整个过程，不利于恢复区域应力场和追溯地质构造发展史.笔者以大连金州地区两条断裂为例，建议在今后区调中应加强对多期活动断层的野外调查及综合研究，丰富图面表达内容，根据断层活动时间和运动性质以颜色、花纹分别表示之，提高图面可读性，较客观地反映出同一断层不同时期的活动性质，总结区域地质构造发展演化历史.

| Abstract: | The multi-stage movement of faults is the result of multiple tectonic cycles and deformations.The faults control the forming and evolving of sedimentary basins,magmatic activities,and the distribution of mineral resources.Therefore,it is important to strengthen the research and survey on the faults with multi-stage movements.In previous geological survey,however,more attentions were paid to faults with the latest or largest movement.Only one stage of activity was expressed.The maps only show simple information,without the whole process of multiple activities and evolution.It is hard to recover the evolution history of regional stress field and geological structures.Taking two faults in Jinzhou area of Dalian as example,the authors propose a suggestion of paying more attention to the survey and synthesized research on the multi-stage movement of faults.The maps should express more content,with activity times and natures of movement,showing the evolution history of regional geological structures. |
