摘要: 通过对兴隆沙XL2孔沉积物磁性特征研究，发现该地区沉积物的磁性矿物以低矫顽力的亚铁磁性矿物为主。按磁化率χ等磁参数曲线的变化特征将XL2孔划分出4个磁性层，同时对比沉积物的粒度特征和微古分析结果，探讨了长江口北支兴隆沙沉积环境的演化过程，以及沉积物磁性特征与沉积环境的关系。

Abstract: Magnetic measurements were conducted on Core XL2 from Xinglong Sand, the Yangtze Estuary. The result indicates that ferromagnetic mineral of multidomain (MD)/pseudosingle domain (PSD) in size dominates the magnetic properties of the samples .The core of XL2 can be divided into four layers according to the variations of magnetic susceptibility and other magnetic parameters.On the basis of magnetic properties, lithofacies and foraminifer and assembled character, it can be found that the mode of environmental evolvement of Xinglong sand bar: tidal current ridge tidal channeltidal current ridgesupratidal zone (intertidal zone and supertidal zone), forming the sedimentary facial sequence of the filled estuary. In addition, the significance of some magnetic parameters on determining sedimentary hydrodynamics and geochemical environment is also discussed.

摘要: 通过对兴隆沙XL2孔沉积物磁性特征研究，发现该地区沉积物的磁性矿物以低矫顽力的亚铁磁性矿物为主。按磁化率χ等磁参数曲线的变化特征将XL2孔划分出4个磁性层，同时对比沉积物的粒度特征和微古分析结果，探讨了长江口北支兴隆沙沉积环境的演化过程，以及沉积物磁性特征与沉积环境的关系。
