Feodosiyite is a very rare chloride mineral, just recently approved,[1] with the formula Cu11Mg2Cl18(OH)8•16H2O. Its structure is unique.[2] Feodosiyite comes from the Tolbachik volcano, famous for many rare fumarolic minerals.[3] Chemically similar minerals, chlorides containing both copper and magnesium, include haydeeite, paratacamite-(Mg) and tondiite.[4]
