| Abstract: | The research of core XL2 from Xinglong Sand in the North Branch of the Yangtze River estuary has mainly been focused on the modern aggradation through analyzing the sedimentary process of North Branch of the Yangtze River estuary controlled by the hydrodynamic conditions, and also there is research work on the sedimentary environment. Using many samples in the profile of core XL2, we do the particle analysis, the environment magnetic analysis and the macrofossil analysis. Then the main results can be concluded through above-mentioned analyses. The results make us know the pattern of environmental evolvement of core XL2. And further we can speculate on the law of environmental evolvement of the North Branch of Yangtze River estuary. |
