The REE biogeochemical signatures, shown by the collected plants, reflect the patterns of the respective soils. The Eu and Ce anomalies shown by some plant samples are inherited from soils, as well. The higher contents of REE observed in fern samples confirm they are accumulators and reflect the abundance of REE in the soils of Pitinga Mine region.

Abstract Concentrations of the rare earth elements (REE), Th and U have been determined in thermal waters emerging from a number of locations in and around the Idaho Batholith. Previous investigators have suggested that the source of heat for the geothermal systems studied is the radioactive decay of K, Th and U which are enriched in the rocks through which the fluids flow.

The Aqueous Geochemistry of Trivalent Rare Earth

The aqueous solution chemistry of trivalent REE, Ga and In at elevated temperatures is relevant to radioactive waste disposal,economic geology, environmental geochemistry and a variety of other applications. In each of these areas, the ability to model aqueous mass transfer of these elements is essential and dependent on the availability of high-quality thermodynamic data.
