Particle size characteristics of sediments is a good sign of judgment of sedimentary environment and water power
contribute to the determination of sedimentary environments.Based on the core observation
a large number of probability cumulative grain size curves were plotted using the date of particle size annlysis of coring wells.There were four different types of curves:one-segment pattern、two-segment pattern、three-segment pattern、multi-segment pattern
and the feature of different types curves were analyzed in detail.At the same time
combined with its selectivity、skewness、peakedness
and so on.Turbidites and Delta(river)depositional environment were identified through the use of Sahu discriminant function of particle size and CM diagram.Curve characteristics of particle size show traction current role and turbidity of depression center
which strongly infuenced the sedimentary environment on the edge of the eastern slope.
