基面抬升、溯源堆积、依次退积叠置是下游河段古河谷厚层连续沉积产生的关键。基于此点,对现有古河谷沉积模式和高分辨率层序地层学研究的若干问题作了讨论。

Retrogressive aggradation is the main cause of thick continous deposits in the lower reach of the incised paleovalley when sea-level rises.On the basis of this,this paper discusses the exisiting paleovalley sedimentary model and some problems in high-resolution sequence stratigraphy study.
