In eastern Slovakia, NE from Byšta village, mordenit has been found in a perlitized glassy margin of the rhyolite rock body. The mordenite which makes up to 40 - 60 % of tho rock, is charakteristically needle - like and fibrous, and forms bundles of fibres and needles inside the geodes with outershells of devitrified volca-nic glass. The mordenite itself exhibits a high chemical and thermal stability. The zeolitized rock after proper mechani- cal and thermal treatment has been succesfully studied in the laboratory as adsorbent of water vapor and other gases from air. Using the ion - exchange properties, the treated rock was used in the experiments for the removal of some cations from low-lever waste waters ( Cs+, Pb2+, Fe3+, Hg2+ ).
