Rare earth elements as indicators of pedogenic processes in an erosional toposequence of old soils, Burgundy, France

摘要

Our work aims at using rare earth elements (REE) as tracers of pedogenic processes. To understand the mobilization of REE by the different pedogenic processes, we studied REE, besides major elements, in different particle-size and mineralogical fractions along an erosional soil toposequence. Preliminary results are in agreement with literature and demonstrate the potential of REE as tracers of pathogenic processes.
