| 摘 要： | 上新世末以来滇西地区发生大面积掀斜隆升构造运动, 同时伴随块体的差异性升降运动。 在这种构造背景下, 怒江断裂带南段形成了一系列断陷盆地, 其中道街盆地是面积最大的一个盆地。 本文利用野外地质考察、 钻探和后差分GPS实测剖面等方法对该盆地第四纪地层和控盆断裂进行研究, 认为道街盆地控盆断裂最新活动时代为中—晚更新世之间, 而盆地内部断层晚更新世以来仍有活动表现。 |

| Abstract: | Since the late Pliocene,a large area of western Yunnan has experienced tectonic movements of tilting uplift,accompanied by different lifting movement among the blocks.In this tectonic context,a series of faulted basins formed in the southern section of the Nujiang fault zone,and Daojie basin is the largest one.The study of Quaternary strata and basin-controlled faults of the Daojie basin in terms of geologic expedition,drilling,surveying profile with virtue deferential GPS indicate that the latest activity ... |
