Crystal chemistry of ferriallanite-(Ce) from Nya Bastnäs, Sweden: Chemical and spectroscopic study

Abstract A second study of ferriallanite-(Ce) from Nya Bastnäs, Sweden, extends current data by using electron probe micro-analysis (EPMA), laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) analysis and brings new insights about its crystal chemistry obtained Raman spectroscopy. The presents the first spectra for member allanite group (not considering rather low-quality published in preceding papers). material does not show significant radiation damage, which is rare as allanite-group minerals often have undergone metamictisation due to amounts incorporated radionuclides (U, Th). Some interior regions pronounced zoning that correlates with variations Raman-band positions. In spite REE content, virtually non-luminescent. New additional allanite-(Ce) Oßling, Germany Domanínek, Czech Republic are also presented, were used comparison.
