摘要

韩江三角洲从晚更新世中期开始沉积,经历了Q32-1的古冲积扇、Q32-2的占三角洲、Q33的风化和新冲积扇、Q41—Q42-1的新三角洲、Q42-2的贝壳堤和沼泽以及Q43的沙堤-泻湖等六个发育阶段。发育模式为河流冲积扇与三角洲的交替发展。重新划分了三角洲的界线,面积为915.08km2。划分出二类十亚类地貌类型。

Abstract

It is considered that geomorphological develoment of the Hanjiang River Delta is deeply affected by fault-block tectonics based on the analysis of sedimentology and chronology including the analysis of diatom, foraminfera, ostracoda, spore-pollen, shell, grain-size, trace element and heavy mineral, and datings of 14C and TL, from 40 borehole sections of the delta.
