“…The ZnO 3 Cl tetrahedra, as in belousovite, are the most common, whereas ZnO 4 Cl tetragonal pyramids are very rare. Tetrahedra of ZnO 3 Cl were reported recently in the structure of another exhalative mineral, chubarovite, KZn 2 (BO 3 )Cl 2 (Pekov et al ., 2015 a ), also found in the sublimates of active fumaroles at the Second and First scoria cones of the Northern Breakthrough of the Great Fissure Tolbachik eruption. The topology of layers in chubarovite is completely different from that of belousovite.…”

“…A variety of zinc minerals sensu stricto (i.e. minerals with independent crystallographic positions of Zn) are known from fumaroles of the First and Second scoria cones: sofiite, Zn 2 (SeO 3 )Cl 2 (Semenova et al ., 1992), prewittite, KPb 1.5 ZnCu 6 (SeO 3 ) 2 O 2 Cl 10 (Shuvalov et al ., 2013), chubarovite, KZn 2 (BO 3 )Cl 2 (Pekov et al ., 2015 a ), mellizinkalite, K 3 Zn 2 Cl 7 (Pekov et al ., 2015 b ), flinteite, K 2 ZnCl 4 (Pekov et al ., 2015 c ), cryobostryxite, KZnCl 3 ·2H 2 O (Pekov et al ., 2015 d ), zincobradaczekite, NaZn 2 Cu 2 (AsO 4 ) 3 (Pekov et al ., 2016 a ), zincomenite, ZnSeO 3 (Pekov et al ., 2016 b ) and pharmazincite, KZnAsO 4 (Pekov et al ., 2017). The first sulfate Zn mineral hermannjahnite CuZn(SO 4 ) 2 was described only recently from the new fumaroles of the Fissure Tolbachik Eruption 2012–13 and fumaroles of the Great Fissure Tolbachik Eruption 1975–76 (Siidra et al ., 2017 c ).…”

“…Earlier, we noted (Siidra et al, 2018c) that the ZnO 3 Cl tetrahedron is observed most commonly among cases of mixed-ligand zinc coordination. Besides belousovite and its analogs, it is also present in the structures of minerals simonkolleite Zn 5 (OH) 8 Cl 2 ÁH 2 O (Hawthorne & Sokolova, 2002), chubarovite KZn 2 (BO 3 )Cl 2 (Pekov et al, 2015) and gordaite NaZn 4 (SO 4 )(OH) 6 ClÁ6H 2 O (Zhu et al, 1997), as well as in two synthetic compounds, CaZn 8 -(SO 4 ) 2 (OH) 12 Cl 2 (H 2 O) 9 (Burns et al, 1998) and BaZn-(TeO 3 )Cl 2 (Jiang et al, 2006).…”

“…Кроме того, немалое количество Zn в эксгаляционных отложениях Толбачика рассеяно в виде значительной (целые мас.%) изоморфной примеси, в первую очередь по Cu 2+ -в различных оксосолях меди (Pekov et al, 2018a,d), в меньшей степени по Al в As-содержащих калиевых полевых шпатах (Vergasova et al, 2004b;Shchipalkina et al, 2018) и по Mg в шпинели (Pekov et al, 2018b). Интересно, что в цинковых минералах из фумарольных эксгаляций Толбачика оказалась устойчивой ранее не встречавшая в природе "связка" трех видообразующих элементов K-Zn-Cl: здесь открыто три таких хлорида -меллицинкалит K3Zn2Cl7, флинтеит K2ZnCl4 и криобостриксит KZnCl3•2H2O (Pekov et al, 2014d), хлорборат чубаровит KZn2(BO3)Cl2 (Pekov et al, 2015e) и хлорсульфат белоусовит KZn(SO4)Cl (Siidra et al, 2018b); все эти компоненты присутствуют как видообразующие и в прюиттите KPb1.5ZnCu6O2(Se 4+ O3)2Cl (Shuvalov et al, 2013). Отметим, что возгоны состава K2ZnCl4 (аналог флинтеита?…”
