Abstract

Ba-micas including magnesian kinoshitalite (XMg more than 0.99) were found in sulphide-rich dolomite marbles at the Rožná uranium deposit, Moldanubicum, Czech Republic. The Ba-micas (phlogopite with Ba > 0.280 apfu and kinoshitalite with Ba from 0.869 to 1.244 apfu) are Mn, Fe and Ti-poor in comparison to other Ba-micas described up to date. The main substitution mechanism in Ba-micas is (Ba2+,Ca2+) (Al3+) (K+,Na+)-1 Si4+-1. Relatively high content of Mn in silicates and carbonates from the host marble is in contrast to the chemistry of Ba-micas. Barium and manganese show distinct behaviour during metamorphism. Manganese and iron were probably partitioned to metamorphic sphalerite and pyrrhotite relative to (Mn, Fe)-poor Ba-micas. Barium concentrated in mica minerals and the system was evidently Ba-depleted in late stages.

Abstract (in Czech)

Ba-slídy včetně Mg-bohatého kinoshitalitu, byly nalezeny v dolomitických mramorech s vtroušenými sulfidy v prostoru uranového ložiska Rožná, moldanubikum, Česká republika. Uvedené fylosilikáty jsou podrobně mineralogicky popsány a analyzovány, řešeny jsou migrace a redistribuce Ba, Mn a Fe mezi metamorfními minerály a sulfidy mramorů.
