The result shows that the sand bodies in wx583 and x176x1 of Xin176 area are beach-bar sand bodies transported from Guangrao Salient and formed by fluvial and wave, whereas the sand bodies in n114x1 and w587 were transported from the Qingtuozi Salient in the form of gravity flow and mixed with clastic materials transported from Guangrao Salient, and then transformed by wave after the deposition of mixed sediments.
