WebMar 12, 2024 · Goethite is an iron oxide hydroxide, although manganese can substitute for up to 5 percent of the iron. It forms as a weathering product in the oxidation zones of veins of iron minerals, such as pyrite, magnetite and siderite. Where does goethite occur in … WebGoethite can form in a few different ways. The most common process is when iron-rich minerals undergo weathering, oxidizing to change their ferrous (Fe2+) iron to ferric (Fe3+) iron. This oxidation means goethite is often found at Earth’s surface.
