Goethite vs Limonite What's the difference? | WikiDiff
As nouns the difference between goethite and limonite is that goethite is an iron oxyhydroxide that is the main constituent of rust while limonite is any of several natural hydrous iron oxides; often a mixture of goethite and hemite with clays andAn oxide of iron Limonite Hydrous sesquioxide of iron, an important ore of iron, occurring in stalactitic, mammillary, or earthy forms, of a dark brown color, and yellowish brownGoethite vs Limonite — What’s the Difference?
