Summary:
This BSc Thesis concerns the study of REE cyclosilicate (eudialyte-type) minerals, originating in Greenland and Russia, by spectroscopic techniques (Mössbauer spectroscopy, ICP-OES/MS, and -ray spectrometry). The aim was to investigate structural and compositional features of certain elements (e.g. Fe) with emphasis in REE and actinides (U, Th). At the same time the minerals were complementary characterized by PXRD and SEM-EDS. The results constitute a contribution to the mineralogy and geochemistry of a geological material exhibiting an importance for the modern industry/technology, as source of critical metals (REE), and also arising environmental issues due to radioactivity content.
