Gismondine-Sr, recently discovered in the Hatrurim Complex in Israel, has been recognised in a xenolith sample from the Bellerberg volcano in Germany. The empirical crystal-chemical formula indicates elevated K content: (Sr1.74Ca1.05Ba0.09K1.56Na0.49)Σ4.93[Al7.98Si8.06O32]⋅9.62H2O. Additionally, Ba-rich gismondine and amicite have been found in the low-temperature mineral association of the pyrometamorphic rock from the Hatrurim Complex. The Raman spectra of the studied zeolites and the crystal structure of gismondine-Sr from the second occurrence are presented. A review of zeolites with GIS framework-type structure leads to the following conclusions: (1) garronite-Na and gobbinsite are equivalent and constitute a solid solution with garronite-Ca; (2) gismondine-Ca, -Sr, and amicite belong to one mineral series; (3) two zeolites series with different R-factors (defined as Si/(Si+Al+Fe)) can be distinguished within GIS topology: the garronite series (R > 0.6) including garronite-Ca and gobbinsite, with general formula (MyD0.5(x–y))[AlxSi(16–x)O32]⋅nH2O, where M and D refer to monovalent and divalent cations, respectively; and the gismondine series, including amicite, gismondine-Sr and gismondine-Ca, with R ≈ 0.5, and the general formula (MyD0.5(8–y))[Al8Si8O32]⋅nH2O. The Raman band between 475 cm–1 and 485 cm–1 is distinctive for the garronite series, whereas the band around 460 cm–1 is characteristic of the gismondine series. On the basis of these findings, a revision of GIS zeolites nomenclature is suggested.

最近在以色列哈特鲁林杂岩中发现的吉斯蒙丁-Sr 已在德国贝勒贝格火山的捕虏体样本中得到确认。经验晶体化学式表明 K 含量升高： (Sr 1.74 Ca 1.05 Ba 0.09 K 1.56 Na 0.49 ) Σ4.93 [Al 7.98 Si 8.06 O 32 ]⋅9.62H 2O. 此外，在哈特鲁里姆杂岩的火变质岩的低温矿物组合中还发现了富含 Ba 的吉斯蒙石和阿米石。给出了所研究的沸石的拉曼光谱和第二次出现的吉斯蒙定-Sr 的晶体结构。通过对GIS骨架型结构沸石的综述，得出以下结论：（1）菱沸石-Na和戈宾沸石是等价的，并与菱沸石-Ca构成固溶体；(2)吉斯蒙碱-Ca、-Sr、伞石同属于一个矿物系列；(3) 可以在GIS拓扑中区分具有不同R因子（定义为 Si/(Si+Al+Fe)）的两个沸石系列：菱沸石系列 ( R> 0.6) 包括菱沸石-Ca 和戈宾矿，通式为 (M y D 0.5( x – y ) )[Al x Si (16– x ) O 32 ]⋅ n H 2 O，其中 M 和 D 指单价，分别为二价阳离子；吉斯蒙定系列，包括胶石、吉斯蒙定-Sr和吉斯蒙定-Ca，R ≈ 0.5，通式为(M y D 0.5(8– y ) )[Al 8 Si 8 O 32 ]⋅ n H 2 O。 475 cm 之间的拉曼带–1和 485 cm –1是尖晶石系列的特征，而 460 cm –1周围的带是吉斯蒙丁系列的特征。根据这些发现，建议修订GIS沸石命名法。
