ABSTRACT
Rare Earth Elements were measured using Instrumental neutron activation analysis in soils from the uranium mineralized Singhbhum Thrust Belt. The trend of the Rare Earth Elements was Ce > La > Nd > Sm > Yb > Eu,Tb > Lu. Light Rare Earth enrichment and Heavy Rare Earth depletion, observed using indicator ratios, showed preferential association of Light Rare Earths with clays. Geo-accumulation index <1 and Enrichment factors ranging from 0.06 to 3.54 indicate none to moderate rare earth mineralization. A positive Ce anomaly and negative Eu anomaly indicate oxidative environment and plagioclase depletion, respectively.
