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.[1][2]

Relation to other minerals

Structure of kainotropite is unique. However, there are other minerals containing both copper and divanadate group, like engelhauptite and volborthite.[3][4]
