摘要
Since the Late Pliocene, a large area of western Yunnan Province 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.
