摘要
The palaeochannels in the studied region are divided into four stages by such methods as 14C dating. Marine (saltwater) transgression in the palaeochannels has been studied as a focal point. Palaeochannels are the main passageway through which the seawater (saltwater) transgresses. The seawater (saltwater) transgresses at a high speed, by many means and in a changeable dynamic state.
