  • Rare earth element

    The rare earth element concentrations are not typically affected by sea and river waters, as rare earth elements are insoluble and thus have very low concentrations in these fluids. As a result, when a sediment is transported, rare earth element concentrations are unaffected by the fluid and instead the rock retains the rare earth element concentration from its source.
