Goethite | mineral | Britannica, Goethite, a widespread iron oxide mineral [α-FeO(OH)] and the most common ingredient of iron rust It was named in 1806 for JW von Goethe, a German poet and philosopher with a keen interest in minerals The name was originally applied to lepidocrocite [γ-FeO(OH)], a less common mineral with the smagnetite hematite limonite and siderite are ores, Types of Iron Ore: The Difference Between Hematite vsKnow More Ore is most often found in the form of hematite and magnetite, though goethite, limonite and siderite types are also common Approximately 98 percent of the iron,What is goethite used for?, Limonite is not a true mineral but a mixture of similar hydrated iron oxide minerals Most of limonite is made up of Goethite Massive Goethite and Limonite can be indistinguishable Limonite forms mostly in or near oxidized iron and other metal ore deposits, and as sedimentary bedsClassification of Sedimentary Rocks, Chiefly: Limonite, Siderite, Goethite, Chamosite, Hematite: Hematite Oolite: >50% oolitic Limonite Oolite: >50% oolitic Oolitic Iron Ore: < 50% oolitic Siderite (Iron carbonate): chiefly siderite, crystalline: Limonitic or Hematitic (Ferruginous) Limestone, Etc All varieties in the Calcite-Dolomite horizontal column are possible here CarbonLimonite | mineral | Britannica, Limonite, one of the major iron minerals, hydrated ferric oxide (FeO(OH) n H 2 O) It was originally considered one of a series of such oxides; later it was thought to be the amorphous equivalent of goethite and lepidocrocite, but X-ray studies have shown that most so-called limonite is actually goethite.
