All rights reserved. Laumontite and heulandite-Ca were found in the cracks and cavities of Permian basalt (Malužiná Formation, Ip oltica Group of the Hronicum Unit), in the eastern part of the Kozie Chrbty Mts., at Spišská Teplica Štefánikova and Lučivná Lopušná Dolina localities. Laumontite has a relatively monotonous chemical composition, only K content reaches up to 0.75 apfu. Average crystallochemical formula of laumontite (both occurrences) is (K 0.41 Na 0.06 Ca 3.61 ) Σ4.08 [Si 16.03 A l7.54 ] Σ23.56 O 48 ·18H 2 O, Si/Al ratio 2.13. Main diffraction maxima d(I) of laumontite are 9.461(100), 6.844(44), 4.157(48), 3.508(33), 3.272(22), unit cell parameters: a = 14.738(1) Å, b = 13.087(1) Å, c = 7.554(1) Å, β = 111.84°, V = 1352.3 Å3. Ca is dominant component in heulandite-Ca from the Štefánikova occurrence (2.18 2.69 apfu), from other admixtures, significantly increased is K content (1.30 2.35 apfu). Less important are Ba (0.05 0.7 apfu) and Sr (0.23 0.60 apfu), Na content reached up to 0.26 apfu. Average chemical composition of studied heulandite-Ca corresponds to formula (K 1.79 Na 0.16 Ca 2.39 Ba 0.38 Sr 0.39 Fe 0.13 ) Σ5.24 [Si 26 .82Al 8.94 ] Σ35.76 O 72 ·24H 2 O, Si/Al ratio 3.00. Its main diffraction maxima d(I) are 8.954(100), 4.650(17), 3.976(18), 3.897(18), 2.973(37), unit cell parameters: a = 17.786(1) Å, b = 17.930(1) Å, c = 7.4338(1) Å, β = 115.93°, V = 2131.9 Å3. Zeolites probably originated during the Alpine orogeny, at the reduced p-T conditions after a peak of the prehnite-pumpellyite facies of basalt metamorphosis. The minimum estimated conditions of their origin are T ~ 210 °C and p 2.1 2.4 kbar, corresponding to the burial depth of Hronicum basalts around 7 km, in the time of zeolites formation.
