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
