Is goethite a metamorphic?
Is goethite a metamorphic?
Goethite is an iron oxyhydroxide. The formation of goethite is marked by the oxidation state change of Fe2+ (ferrous) to Fe3+ (ferric) iron, which allows for goethite to exist at the earth’s surface. Hematite is one of the most abundant minerals and is found in sedimentary, metamorphic, and igneous rocks.
