Geochemical Characteristics of Rare Earth Elements in Different Types of Soils in China

摘要

The contents, distribution patterns, and specification of rare earth elements(REEs) in latosol(tropical zone), red earth(middle subtropical earth), yellow brown soil(northern sub- tropical earth), cinnamon soil(warm temperate zone), leached chernozem(temperate zone)and albic bleached soil(temperate zone) in china were determined with instrumental neutron activation analysis(NAA) and systematically studied. The results indicate that yellow brown soil, cinnamon soil, leached chernozem and albic bleached soil are characterized by light REEs(LREEs) enrich- ment and Eu-depletion, while latosol and red earth are characterized by LREEs enrichment and Ce-depletion.
