Ksenotym w łupkach łyszczykowych zmineralizowanych kasyterytem z pasma łupkowego Starej Kamienicy

Abstract

Xenotime in mica schist with cassiterite mineralization in Stara Kamienica Range.Summary. Xenotime in mica schists with chlorite was analysed with EDS microprobe combined with scanning electron microscope JEOL JSM 35. The samples come from two boreholes (C-XI-41 and C-XII-54) drilled in the western part of Stara Kamienica Range. Xenotime crystals are of zoning and patchy character due to the changing composition of HREE elements. Xenotime is probably of hydrothermal origin which is connected with premetamorphic cassiterite and sulfide mineralization.
