Alexander F. Volborth

Formula:

Cu₃(V₂O₇)(OH)₂ · 2H₂O

Colour:

Olive-green, yellow-green; green to yellow-green in transmitted light.

Lustre:

Vitreous, Waxy, Greasy, Pearly

Hardness:

3½

Specific Gravity:

3.5 - 3.8

Crystal System:

Monoclinic

Member of:

Volborthite Group

Name:

Named in honor of Alexander Fedorovich Volborth (Александр Федорович Фольборт) (1800, Mogilev, Russian Empire - 1876, St. Petersburg, Russian Empire), paleontologist, who first noted the mineral. At least ten fossil species are also named after him.

Type Locality:

ⓘ Sofronovskii Cu Mine, Yugovskii Zavod (Kalinino), Kungursky District, Perm Krai, Russia

A secondary mineral found in the oxidized zones of vanadium-bearing hydrothermal deposits.

At least two different monoclinic space-group variants (C2/m, C2/c) seem to be stable at ambient temperature.

Visually similar to vésigniéite.
Structurally related to engelhauptite.
