POSSIBILITIES OF IDENTIFICATION OF RARE EARTH ELEMENTS BY PORTABLE XRF SPECTROMETERS IN DRILL CORES FROM THE EŁK SYENITE MASSIF (EŁK IG 3 BOREHOLE, NE POLAND)
Journal Title: Biuletyn Państwowego Instytutu Geologicznego - Year 2015, Vol 465, Issue 465
Abstract
The main aim of this study is to determine the contents of rare earth metals, using p-XRF, in the Carboniferous Ełk syenite massif that cuts the Precambrian basement of the East European Platform. The paper presents the results of drill core study in the Ełk IG 3 borehole. In situ chemical analyses of borehole materials were performed using the portable XRF Olympus Delta 50 Premium spectrometer (4 W Ta anode X-ray tube, 50 kV). Prior to analyses of natural rock samples the spectrometer parameters were optimized for selected rare earth elements, such as Y, La and Ce, as well as other elements ,such as Zr, Hf, U and Th. Handheld XRF non-destructive analyses have allowed the identification of anomalies of rare earth elements and places for further detailed petrographic and mineralogical analyses.
