Abstract
A new locality of zeolite minerals occurs on the NE edge of the Jedlka village, at the SE slope of the Hlídka hill, 2 km to W of Benešov nad Ploučnicí (northern Bohemia, Czech Republic). The mineralization is developed in Cenozoic analcime-nepheline tephrite. Ten zeolite mineral species (gmelinite-K, analcime, harmotome, chabazite-Ca, lévyne-Ca, mezolite, natrolite, offretite, phillipsite-K, thomsonite-Ca) were found in small amygdule cavities of tephrite. The most interesting is gmelinite-K, a rare zeolite worldwide, which forms clear, white or slightly yellowish, hexagonal lenticular crystals up to 7 mm, always intergrown with the chabazite-Ca. The unit-cell parameters of gmelinite-K, refined from the powder X-ray data, are a = 13.795 (19), c = 9.811(6) Å and V = 1616.8(3) Å3; its quantitative chemical analyses correspond to the empirical formula (K2.32Ca1.86Sr0.53Na0.20Ba0.19)Σ5.10(Al8.14Si16.01O48)·22H2O.
