Geochemical fractionation of the larger rare earth elements tends to follow simple trends, and, as a result, the relative abundance of these elements in the majority of rocks and minerals can be plotted as a smooth curve. An exception to this general rule is predictable in the case of the mineral cerianite, which can be expected to contain anomalously high concentrations of cerium (present in the quadrivalent state). The present paper demonstrates that this expected anomaly does not occur in the cerianite found in an Iveland pegmatite, and the significance of this fact is discussed.
