Abstract
Radioactive minerals of the gneiss of Sopron Mountains were analysed by micro-PIXE method at the Debrecen scanning nuclear microprobe. Zircon and monazite minerals were identified with detectable amount of U and Th. Qualitative elemental maps and quantitative concentration data were obtained on 20 minerals. U and Th concentrations were between few 100 ppm and 10 wt%. The size of the minerals varied between few micrometers and 100 microns, the distribution of U and Th within the grains was inhomogeneous. These radioactive minerals occurred in veins enriched with Fe.
