Characteristics of the Quaternary Tectonic Activity of the Daojie Basin in the South Section of Nujiang Fault Zone

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.
