Add to ORKGMineralogical study was made of one sample each of weathering products of siderite and ferroan rhodochrosite. The siderite ore from Fukuo Mine, Fukushima Prefecture, had been altered into goethite by weathering, and ferroan rhodochrosite from Yamato Mine of the same prefecture had been altered into an aggregate of goethite, γ-type ramsdellite, pyrolusite and cryptomelane
