Fukuchilite Cu3FeS8 is a copper iron sulfide named after the Japanese mineralogist Nobuyo Fukuchi (1877–1934) that occurs in ore bodies of gypsum-anhydrite at the intersection points of small masses of barite covellite gypsum and pyrite and is mostly found in the Hanawa mine in the Akita prefecture of Honshū Japan where it was first discovered in 1969.
