N2 - © 2015 E. Schweizerbart'sche Verlagsbuchhandlung, D-70176 Stuttgart.The new mineral cryobostryxite, KZnCl3-·2H2O, is found in the Northern fumarole field at the First scoria cone of the Northern Breakthrough of the Great Tolbachik Fissure Eruption, Tolbachik volcano, Kamchatka, Russia. Cryobostryxite is a secondary mineral formed in the upper, moderately hot (30-80 °C) zone of active fumaroles, probably as a product of the interactions between high-temperature volcanic sublimates and meteoric water. It is associated with gypsum, ralstonite and opal; earlier, primary minerals of the assemblage are sellaite, fluorite, halite, anhydrite, cotunnite, sofiite, flinteite, chubarovite, anglesite, challacolloite, zincomenite, saltonseaite, hollandite, hematite, jakobssonite, leonardsenite and olsacherite. Cryobostryxite occurs as anthodites (up to 0.5 × 2 mm), their aggregates (up to 4 × 5 mm), granular crusts (up to 2 × 2 mm) and, rarely, coarse prismatic to acicular crystals (up to 0.2 × 1 mm). The mineral is transp
