Xigeda formation is a famous fluvial-lacustrine sedimentation formed in late cenozoic in southwest China
distributed in the valley of Dadu River
Anning River
Chin-sha River etc.The age of Xigeda formation
ranges between 4.18 and 1.78 Ma BP
depending on the magnetic stratigraphy research of the stratigraphic section.Quartz Ti-center in ESR dating of sand samples from several typical sections of Xigeda formation in Sichuan shows that they are sediments in mid-pleistocene.Comparing the ESR ages and mainly normal polarity
Xigeda formation can be confirmed in Brunhes epoch according to magnetic stratigraphy.
