The modern Yellow Sea between mainland China and
the Korean peninsula (Fig. 11.3b) is an example of an
epicontinental shelf sea oversupplied with terrigenous material from major rivers, especially the Huanghe and the
Changjiang (Yangtze, cf. Sect. 9.3). Since post-glacial sealevel rise had established approximately the present basin

dominated by silicic1astic mud deposition (mainly silty

carbonate (Lee and Chough 1989; Alexander et al. 1991).
In the northern portion (Gulf of Bohai), where the influence of the modern Huanghe River is greatest, the Holocene sedimentation rate attains 30 mika (solid dry material); in the central portion of the Yellow Sea, the sedimentation rate is still around 3 mika, and in the south it is 0.5
