| Popis | Veselovskýite, (Zn,Cu,Co)Cu4(AsO4)2(AsO3OH)2 . 9H2O, is a new supergene mineral from the Geister vein, Mine Rovnost at the Jachymov ore district (St. Joachimsthal), Czech Republic, commonly associated with strashimirite and blue amorphous Cu arsenate. It forms aggregates, up to 8 x 5 x 1 mm in size, consisting of lath-like to thin-tabular crystals, up to 1 mm long, commonly forming complicated intergrowths, no twinning was observed. Veselovskyite is translucent (aggregates) to transparent (crystals), colourless to greyish white (with a slight greenish tint). It has a greyish white streak with a greenish tint, a vitreous luster, does not fluoresce under both short- and long-wave ultraviolet light. Cleavage on (001) is perfect, Mohs hardness is similar to 2-3, and veselovskyite is very brittle with an irregular fracture and calculated density 3.28 g/cm3. All structural and chemical data are given in the paper. |
