Weathering of Iron-Rich Minerals: Goethite often forms as a weathering product of other iron-bearing minerals, such as pyrite (iron sulfide), magnetite (iron oxide), and siderite (iron carbonate). These minerals can undergo oxidation and hydrolysis in the presence of water and oxygen, leading to the formation of goethite.
