A leaching experiment using 5 REE oxides and gravelly, sandy loam soils was conducted and the leaching and binding characteristics of the oxides for the soils were examined. The experiment showed little leaching of the oxides and an enrichment
of various size classes of soil particles with the oxides, which reflected the strong binding capability of the REE oxides with the gravelly, sandy loam soils. In this study, the method based on measuring the REE concentrations for 4 particle size groups
The aims of this study were : to examine the applicability of the Rare Earth Element (REE) technique for successive storm events for a period of nearly 4 years; to evaluate the relative contribution of each morphological element to sediment yield
from the watershed; and to examine the potential sources of error related to using the REE technique for a multi-year of period to study sediment sources.
