Editing Yangtze (section)

=== Geologic history ===
Although the mouth of the [[Yellow River]] has fluctuated widely north and south of the [[Shandong peninsula]] within the historical record, the Yangtze has remained largely static. Based on studies of [[deposition (geology)|sedimentation rates]], however, it is unlikely that the present discharge site predates the [[late Miocene]] ({{c.|lk=no|11}} [[megaannum|Ma]]).<ref>Métivier, F. & al.
