Geologic Distribution: Europium occurs in minor amounts in the trace minerals monazite and allanite 1. Monazite was found in trace amounts in 22 of 24 coal samples examined using scanning electron microscopy (SEM) in an unpublished study by the WVGES. West Virginia coals contained a mean of 0.33 ppm Eu correlated slightly with ash yield and trace elements related to ash-forming minerals. Europium is one of the REE and correlated mainly with other REE. Europium also displayed no trends in stratigraphic or areal distribution.
Economic Impact: Europium is of no economic impact. Europium is widely used as a red phosphor in color TV tubes 2.
Environmental Impact: Rare earth elements, including europium, have no environmental impact in coal mining or utilization 1.
