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.

This goethite sample was formed after pyrite when chemical conditions changed. It retains the pyrite's basic cubic shape, so it is a pseudomorph. Pyrite is an iron sulfide, and goethite is an iron oxide hydroxide. This compares the goethite sample with a cubic pyrite sample from Ambassaguas mine, Amejun, La Rioja, Spain.
