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 of basin-controlled faults of the Daojie basin is the period between middle Pleistocene and late Pleistocene, and the faults within the basin have been active since late Pleistocene.

Key words: Faulted basin, Filled sequence, Structural framework
