“12x12x10 mm group of Kesterite crystals covered by dense films of greyish Vismirnovite. Associating mineral is very minor green Malachite. Analytical data are available on the daughter photo. Pavel M. Kartashov analytical data and collection, Jiangbin photo.”

“Back side of 12x12x10 mm group of Kesterite crystals covered by dense films of greyish Vismirnovite. Associating mineral is very minor green Malachite. Analytical data are available on the daughter photo. Pavel M. Kartashov analytical data and collection, Jiangbin photo.”

“SEM image of Vismirnovite film. Note globular structure of the inner side of the film. Pavel M. Kartashov analytical data, collection and photo.”

“Enlarged fragment of previous SEM image of Vismirnovite film. Globular structure of the inner side of the film contacted with Kesterite matrix. Analytical data are available on the daughter photo. Pavel M. Kartashov analytical data, collection and photo. ”

“EDX spectrum of Vismirnovite film groving over Kesterite crystal group from Huya. Small peak of Si is connected with minor admixture of opal. Recalculated formula of Vismirnovite is (Zn0.57Cu0.29Fe0.14)1.00Sn(OH)6.00. Analytical data for other points of the same particle of the film are (Zn0.51Cu0.31Fe0.19)1.01Sn0.99(OH)5.98 and (Zn0.43Cu0.39Fe0.17)0.99Sn1.01(OH)6.02. So we observe here wide isomorphic replacement toward to Mushistonite composition and not so pronounced to Natanite one. Pavel M. Kartashov analytical data, collection and photo.”
