Goethite - Sandatlas

Goethite. Goethite is a common weathering product of iron-bearing minerals like magnetite, pyrite and siderite. It is an oxyhydroxide or iron — FeO (OH). The most characteristic feature of this mineral is brown to yellowish color. It may resemble hematite (Fe 2 O 3 ), but hematite is either gray or reddish. It changes to hematite on dehydration.
