| 摘 要： | 通过对兴隆沙地区沉积物环境磁学特征分析,发现该地区磁性矿物主要以来源于长江亚铁磁性矿物为主,并含有少量的反铁磁性矿物;通过微体古生物特征分析,发现长江口北支沉积物主要由潮流流携带而来.综合环境磁学和微体古生物学特征,得出该地区沉积物的来源是多源的,以长江源为主. |

| Abstract: | Through an analysis of the magnetic characteristic on Xinglongsha Island, it is discovered that the ferrous magnetic mineral is mainly from Changjiang River.By analyzing the features of foraminifer, we find that the sedimental substance at the north branch of Changjiang River stems from torrents and tides along the coast of north Jiangsu. In view of the features of the environmental magnetics and of foraminifera, it is concludled that the source of the sedimental substance in that region larea is varied, with that of Changjrang River as the dominant one. |
| Keywords: | the north branch of Changjiang River estuary the tidal sandy sediments the source of sediments |
