Description 1438-1448
Based on the analysis of 3,372 sediment samples and 108 km stratigraphy
profiles from the modern Yellow River delta, the results show that fine granule
sediments is primary, clay silt and silt is its main sediment types. It mainly
consists of two parts: saltation load and suspension load, leaking of bed load.
With the decreasing of turbulence intensity seaward, it could be divided into
two different hydrodynamic sedimentary environment, one is a strong
hydrodynamic conditions represented by sedimentary of river bed and river mouth
bar, the other one is represented by prodelta and lateral margin sediments, it
is a week hydrodynamic sedimentary condition. Hyperpycnal flow belongs to the
category of gravity flow and the modern Yellow river
delta is a gravity flow controlled sedimentary system. Hyperpycnal flow
deposits of modern Yellow River delta is an
elliptic sedimentary body which typically
characterized by thin on both sides with thick in the middle and the long axis
parallel to the coastline.
