Based on the analysis of a large number of probability cumulative grain size curves, the combinatorial characteristics have been summarized in the different microfacies of delta. The distributaries channels in delta plain subfacies are the combinatorial characteristics of uphill arched pattern and typical bi-segment pattern. The distributaries channels in delta front subfacies have the combinatorial characteristics of low slop multi-bouncing population-1 suspension population pattern and bi-bouncing population-1 suspension population pattern. The river mouth bars in the delta front, where fluvial action is stronger than wave action, are the combinatorial characteristics of bi-bouncing population-1 suspension pattern and low slop multi-bouncing population-1 suspension population pattern.
