Figure 3.5.5 3.5. 5: Limonite, hydrated oxide of iron. After carbonates, the next most common non-silicate minerals are the oxides, halides, and sulfides. Oxides consist of metal ions covalently bonded with oxygen. The most familiar oxide is rust, which is a combination of iron oxides (Fe 2 O 3) and hydrated oxides.

Mineral luster is a property used to characterize and identify minerals based on their appearance when light interacts with their surfaces. Luster refers to the way light is reflected from a mineral's surface, and it can be described using various terms, each reflecting a specific appearance. Here are the most common types of mineral luster.

Limonite is a mixture of fine-grained hydrated iron oxides. It is chemically similar to goethite (HFeO2), but varies from ideal goethite by having more water. Although goethite is a very common component, limonite can also contain many other minerals. Some are polymorphs of goethite: lepidochrocite, akaganeite and feroxyhyte.
