Goethite oxide
WebGoethite (FeO (OH)): Goethite is an iron oxide hydroxide mineral that often occurs as a weathering product of other iron -bearing minerals, such as hematite and magnetite. It is typically found in soil and sedimentary environments, as well as in some ore deposits. WebIron (hydr)oxides are the most abundant metal oxides, which are widespread on Earth’s surface in the major form of micro/nanoparticles. Dissolution of iron (hydr)oxides significantly controls their compositions on Earth’s surface and is a critical step for the global Fe cycling.
