Abstract: Magnetic measurements were conducted on Core XL2 from Xinglong Sand, the Yangtze Estuary. The result indicates that ferromagnetic mineral of multidomain (MD)/pseudosingle 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 channeltidal current ridgesupratidal 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.
