Short summary
Andreybulakhite, ideally Ni(C2O4) · 2H2O, is a new oxalate mineral, which was discovered on the Kola Peninsula, Russia. Andreybulakhite forms segregations of crystals up to 2 × 1 × 1 mm in size disseminated within the fruiting bodies of Lecanora cf. polytropa lichen, whose colonies overgrow the oxidized surfaces of pyrrhotite–pentlandite–chalcopyrite ore. Andreybulakhite is named in honour of Andrey Glebovich Bulakh of Saint Petersburg State University.
