摘要：

珠江口外第四纪的沉积相,是在高分辨率浅层地震相解释的基础上初步划分的。它包括了河流冲积相、三角洲相、浅海相、潮汐-河口湾相等四个主要的骨架沉积相,一个典型的海底沙丘沙波沉积。沉积相的类型、发展演变和空间分布与区域海平面升降密切相关。

Abstract:

According to high resolution geophysical data inthe 3.5 kHz subbottom profile and single-channel seismic reflection,the Quaternary in the Pearl River mouth shelf can be di-vided into four main sedimentary facies and one special deposit body:fluvial facies,deltaic facies,shallow sea facies,tidal current-bayou facies and sand dune-sand wave deposits.These different sedimentary facies are sedimentary systems that formed in low water level,high water level of different periods and transgressive or regressive conditions con-trolled by regional eustasy during Pleistocene-Holocene.
