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 by Raman spectroscopy. The study presents the first Raman spectra for ferriallanite-(Ce) member of the allanite group (not considering the rather low-quality spectra published in preceding papers). The material does not show significant radiation damage, which is rare as allanite-group minerals often have undergone metamictisation due to significant amounts of incorporated radionuclides (U, Th). Some interior regions show pronounced zoning that correlates with variations in Raman-band positions. In spite of its significant REE content, the material is virtually non-luminescent. New additional data for allanite-(Ce) from Oßling, Germany and Domanínek, Czech Republic are also presented, which were used for comparison.

来自瑞典Nya Bastnäs的铁allanite-(Ce)的晶体化学:化学和光谱研究

来自瑞典Nya Bastnäs的铁allanite-(Ce)的第二项研究通过电子探针微分析(EPMA)，激光烧蚀电感耦合等离子体质谱(LA-ICP-MS)分析扩展了现有数据，并通过拉曼光谱获得了对其晶体化学的新见解。该研究首次获得了铁allanite-(Ce)成员的拉曼光谱(不考虑之前发表的相当低质量的光谱)。该材料没有显示出明显的辐射损伤，这是罕见的，因为由于大量的放射性核素(U, Th)的掺入，allanite族矿物经常发生变质作用。一些内部区域显示出明显的分区，这与拉曼波段位置的变化有关。尽管稀土元素含量很高，但这种材料实际上是不发光的。另外还介绍了来自德国奥ßling和捷克共和国Domanínek的allanite-(Ce)的新附加数据，用于比较。

期刊介绍： Mineralogy and Petrology welcomes manuscripts from the classical fields of mineralogy, igneous and metamorphic petrology, geochemistry, crystallography, as well as their applications in academic experimentation and research, materials science and engineering, for technology, industry, environment, or society. The journal strongly promotes cross-fertilization among Earth-scientific and applied materials-oriented disciplines. Purely descriptive manuscripts on regional topics will not be considered. Mineralogy and Petrology was founded in 1872 by Gustav Tschermak as "Mineralogische und Petrographische Mittheilungen". It is one of Europe''s oldest geoscience journals. Former editors include outstanding names such as Gustav Tschermak, Friedrich Becke, Felix Machatschki, Josef Zemann, and Eugen F. Stumpfl.
