Abstract:
Through the study of the content of rare earth elements and their distribution pattern in the sediments of ODP Site 1146 of ODP Leg 184, their distribution characteristics are determined, namely, LREE is relatively enriched and Eu is in depletion. The REE distribution patterns in the eastern continental shelf, ocean sediment and loess in China are similar. This shows that sediments in the area came mainly from the continent. The enrichment factor (EF) also shows that the continent is the main source of the sediments. The weak negative anomaly of delta Ce, Sigma REE and delta Eu are mainly controlled by changes in climate and the environment in the continental source area, and they have little relevance to seawater. REE correlate slightly with biological action and may mainly exist in the crystal lattice of clay minerals on the continent. The composition of interstitial water in the sediment shows that the diagenetic environment was mainly a reductive environment. The reductive action of sulfate is above 68 mcd and the biological action of methane is under 68 mcd.
