摘要

Abstract

Grain size analysis

X-ray diffraction analysis and biostratigraphy analysis of the structure

composition and formation conditions of the neritic silty clay facies sediments extensively distributed in the central part of the South Yellow Sea showed that the sediments were composed of more than 70% clay

less than 30% silt

had very little or no sand

and were characterized by homogenous texture

soapy feeling

high plasticity

light green gray color and elliptical distribution being about 3 m thick in the center

being thinner towards the margin and finally thinning out. These shelf cyclonic eddy environment sediments formed a sedimentary facies different from that of the sediments in the neighbouring area and revealed the particular sediment dynamic pattern in the environment.
