N2 - The new mineral mellizinkalite, K3Zn2Cl7, is found in the Glavnaya Tenoritovaya fumarole at the Second scoria cone of the Northern Breakthrough of the Great Tolbachik Fissure Eruption, Tolbachik volcano, Kamchatka, Russia. Associated minerals are belloite, avdoninite, eriochalcite, sylvite, halite, carnallite, mitscherlichite, sanguite, chrysothallite, romanorlovite, gypsum, chlorothionite, kainite and earlier hematite, tenorite and chalcocyanite. Mellizinkalite occurs as irregularly shaped grains up to 0.5 mm across or crude elongated crystals up to 0.25 x 1.3 mm, their clusters and crusts up to 2 x 2 mm in area and up to 0.5 mm thick. The mineral is yellow-brown to reddish brown, transparent, with vitreous lustre. It is moderately brittle, slightly plastic. The Mohs' hardness is ca. 2. Cleavage is not observed, the fracture is uneven. D-meas = 2.46(2) and D-calc = 2.49 g cm(-3). Mellizinkalite is optically biaxial (-), alpha = 1.556(5), beta = 1.612(5), gamma = 1.663(5) and 2V(meas) = 85(5)degrees. The Rama
