A total of 294 samples were collected at 10~20 cm intervals along the cored succession for grain size analysis, 93 samples at 20~80 cm intervals for foraminifera identification, and 27 samples at 200 cm intervals for rare earth elements analysis. The lithology, grain size, sedimentary structure, foraminifera, and rare earth elements of Late Quaternary sediments in the borehole SE2 were analyzed to research the sedimentary environment evolution, and the associated distribution variation of rare earth elements in the Qiantang River mouth area. The results indicate that five sedimentary facies, including fluvial channel, floodplain, tidal flat, shallow marine, and estuarine sand bar, can be distinguished, and the rare earth elements distribution is closely related to sedimentary environment.oft-com:office:office" />
