| Abstract: | Fifty topsoil samples collected from 12 different regions of East China have been analyzed for rare earth elements (REEs).
The average REE concentrations of the 50 topsoil samples are much higher than world average and are characterized by LREE-enrichment,
HREE-depletion, Eu-depletion and Ce-enrichment. However, the REE concentration is not strongly affected by the climate of
the sampling site; it is controlled mainly by parent materials. The plot of Ce/Eu against Eu/Sm is proved to be useful to
distinguish different parent materials of topsoil. Each element in the 50 topsoil has a good correlation with its neighboring
element. Seven of the 13 values are above 0.987. |
