zeophyllite, tobermorite, kenotobermorite, fluorapophyllite-(K), chabazite-Ca, phillipsite-K, phillipsite-Ca, thomsonite-Ca, Cenozoic basaltic rocks, powder X-ray diffraction data, unit-cell parameters, chemical composition, Křížový vrch near Cvikov, Czech Republic

Zeophyllite, tobermorite, kenotobermorite, fluorapophylite-(K) and associated zeolites were found in cavities of Cenozoic basaltic rocks of small abandoned quarry at western slope of the Křížový vrch hill (443 m a.s.l.), 1.5 km NE from Cvikov, 13 km NNE from Česká Lípa, Lužické hory Mountains, Czech Republic. Zeophyllite forms colorless spherical aggregates with pearly lustre usually 3 - 4 mm in size, aggregates with diameter up to 1 cm were observed only rarely. It is trigonal, space group R-3, with unit-cell parameters refined from PXRD: a 9.362(2), c 36.470(12) Å and V = 2768.3(1.2) ų. Chemical analyses of zeophyllite correspond to the empirical formula (Ca_12.84Na_0.07)_Σ12.91(Si_9.83Al_0.26)_Σ10.09O₂₈(OH)_1.43 F_8.42· 6H₂O. Tobermorite occurs as snow-white hemispherical to spherical aggregates up to 1 cm in size, it replaces earlier zeophyllite. It is monoclinic, space group Bm, with unit-cell parameters refined from PXRD: a 6.714(4), b 17.375(4), c 22.670(8) Å, γ 123.31(3)° and V 938.2(1.3) ų. On the base of chemical analyses, tobermorite with empirical formula (Ca_4.55Na_0.03K_0.02)_Σ4.60(Si_5.40Al_0.60)_Σ6.00O_15.56(OH)_1.44·5H₂O is accompanied by more rare Ca-poor kenotobermorite with empirical formula (Ca_3.99Na_0.04)_Σ4.03(Si_5.60Al_0.40)_Σ6.00O_14.62(OH)_2.38·5H₂O. Fluorapophyllite-(K) forms abundant prismatic crystals up to 0.5 - 2 cm in size. It is colorless to white with vitreous to greasy lustre. It is tetragonal, space group P4/mnc, with unit-cell parameters refined from PXRD: a 9.0157(13), c 15.7889(19) Å and V = 1283.4(3) ų. Chemical analyses of fluorapophyllite-(K) correspond to the empirical formula (K_0.81Na_0.24)_Σ1.05Ca_4.06(Si_7.25Al_0.47)_Σ8.00O₂₀F_1.05· 8H₂O. Other zeolites, thomsonite-Ca, chabazite-Ca, phillipsite-Ca and -K, were found in association; their PXRD data, unit-cell parameters and chemical compositions are given in the paper.
