RARE EARTH ELEMENTS ANALYSIS FOR PROVENANCE STUDY OF SURFACE SEDIMENTS OFF SOUTH SHANDONG PENINSULA

147 surface sediment samples from the offshore area of the South Shandong peninsula and 46 surface sediment samples from surrounding mid-small rivers were collected for grain size and rare earth element (REE) analysis. On the basis, the distribution pattern of rare earth elements, δEu and δCe anomalies, chondrite-normalized and upper continent crust normalized rare earth elements distribution curves were systematically studied. The results show a pattern of enriched light REE (LREE), flat heavy REE (HREE) and moderate Eu anomaly in the study area. Comparing the pattern with the data from the Yangtze River, the Yellow River and the mid-small rivers from surrounding land, using Ce/La and Sm/Nd as contrasting elements for F_D discriminant function analysis and verified with the ratio of some relatively stable elements, it is inferred that the surface sediments of the study area are mainly coming from the modern Yellow River, with part of the sediments from the medium and small rivers in the surrounding area.
