Kainotropite is a rare vanadate mineral with the formula Cu4FeO2(V2O7)(VO4). It contains trivalent iron. It is one of many fumarolic minerals discovered on the Tolbachik volcano. The name of its parental fumarole is "Yadovitaya", which means poisonous. [2] [3]

Relation to other minerals

Structure of kainotropite is unique. However, there are other minerals containing both copper and divanadate group, like engelhauptite and volborthite. [4] [5]

Cotunnite

Cotunnite is the natural mineral form of lead(II) chloride with formula PbCl2.

Gurimite

Gurimite is a rare mineral with formula Ba3(VO4)2. It is a simple barium vanadate, one of the most simple barium minerals known. It is named after its type locality - Gurim anticline in Israel. It has formed in the rocks of the Hatrurim Formation. Gurimite's stoichiometry is similar to that of copper vanadates mcbirneyite and pseudolyonsite. An example of other barium vanadate mineral is tokyoite.

Feodosiyite is a very rare chloride mineral, just recently approved, with the formula Cu11Mg2Cl18(OH)8•16H2O. Its structure is unique. Feodosiyite comes from the Tolbachik volcano, famous for many rare fumarolic minerals. Chemically similar minerals, chlorides containing both copper and magnesium, include haydeeite, paratacamite-(Mg) and tondiite.

Mesaite is a very rare mineral with formula CaMn2+5(V2O7)3•12H2O. It is monoclinic (space group P2/n). It is related to fianelite, another manganese-rich divanadate. Examples of other divanadate minerals are volborthite, engelhauptite, karpenkoite, and martyite.

Hendekasartorite is a very rare thallium sulfosalt mineral with formula Tl2Pb48As82S172. It is one of recently approved new members of sartorite homologous series, by enneasartorite and heptasartorite. All new members come from Lengenbach quarry in Switzerland, prolific in terms of thallium sulfosalt minerals. Hendekasartorite is chemically similar to edenharterite and hutchinsonite.

Fluorwavellite

Fluorwavellite is a rare phosphate mineral with formula Al3(PO4)2(OH)2F•5H2O. As suggested by its name, it is a fluorine-analogue of wavellite (hence its name), a rather common phosphate mineral. Chemically similar aluminium fluoride phosphate minerals include fluellite, kingite and mitryaevaite.

Kyawthuite is a rare mineral with a simple formula: Bi3+Sb5+O4. It is a natural bismuth antimonate.

Another examples of natural thallium chlorides are steropesite, Tl3BiCl6, and lafossaite, TlCl. Chrysothallite is one of numerous fumarolic minerals discovered among fumarolic sites of the Tolbachik volcano, Kamchatka, Russia The mineral is named in allusion to its colour and thallium content.
