英文摘要 | To identify the weathering intensity and to deduce the provenance of sediments (black-brown soil and loess) from the loess tableland in the Liyang Plain is of great importance for understanding the development and origin of civilization of this critical region in China. The geochemical results show similar REE distribution patterns among sediments sampled from the YC profile in the Liyang Plain, reticulated red soils from the Dongting lake area, Xiashu loess in Zhenjiang, and loess from the Loess Plateau in China. These similarities imply a single provenance, from dust storms. REEs, especially the LREE/HREE ratio and Eu anomaly, can trace weathering intensity. Higher LREE/HREE ratios, and remarkably Eu anomalies, are present in the top loess (L(0)), Lower LREE/HREE ratios and insignificant Eu anomalies are present in black-brown soil (S(0)*) from the Liyang Plain. These demonstrate that the black-brown soils have undergone a lower intensity of weathering than the loess of YC profile. Moreover, CIA values for sediments from the YC profile provide powerful evidence to support the above result. Comparisons of analyses of the REE contents of sediments from the YC profile, of reticulated red soils from the Dongting Lake area, Xiashu loess from the Yangtze River, and loess from the Loess Plateau, clearly show the weathering intensity decreases according to the following sequence: reticulated red soil from the Dongting Lake area > sediments of YC profile from the Liyang Plain, which formed from dust storms a parts per thousand Xiashu loess from lower reach of the Yangtze River > loess from the Loess Plateau. |
