Summary
A new occurrence of monazite from Alinci, SE Yugoslavia, is described. Crystal morphology studies showed that crystals possess a platelike habit on T01 which we regard as a hitherto unknown morphological feature of monazite. The material has been analysed for uranium, thorium and rare earth element content using gamma spectrometry and inductively coupled argon-plasma atomic emission spectrometry (ICPAES). The monazite displays a complex chemical composition, essentially given as (REE+Y,Th,U,Fe)1.001P0.988O4. The infrared absorption spectra and X-ray diffraction data are in agreement with those for terrestrial monazite, although they indicate minor structural variations caused by the REE distribution in the Alinci monazite.
Zusammenfassung
Es wird ein neues Monazitvorkommen von Alinci, Jugoslawien, beschrieben. Kristallmorphologische Studien zeigten, daß die Kristalle einen plattigen Habitus nach (T01) aufweisen, eine nach Wissen der Autoren bisher unbekannte morphologische Erscheinung bei Monazit. Das Material wurde auf die Uran-, Thorium- und Seltenerdgehalte mit Gamma-Spektrometrie und induktiv gekoppelter Argonplasma-Atomabsorptions-Spektrometrie (ICPAES) analysiert. Der Monazit zeigt eine komplexe chemische Zusammensetzung, die im wesentlichen als (REE+Y,Th,U,Fe)1.001P0.988O4 angegeben werden kann. Die Ultrarotspektren und die Röntgenbeugungs-Daten stimmen mit jenen von terrestrischem Monazit überein, obwohl sie kleine strukturelle Variationen anzeigen, die durch die REE-Verteilung im Monazit von Alinci verursacht sind.
