Color is important in mineral identification, but it can be a complicated subject. Experts use color all the time because they have learned the usual colors and the usual exceptions for common minerals. If you're a beginner, pay close attention to color but do not rely on it.
Olivine always has silicon and oxygen as well as iron or magnesium or both, (Mg, Fe)2SiO4. The physical properties of minerals include: How physical properties are used to identify minerals is described in the lesson on Mineral Formation. Mineralogists divide minerals into groups based on chemical composition. mineral is formed through natural processes and has a definite chemical composition. Minerals can be identified by their characteristic physical properties such as crystalline structure, hardness, density, flammability, and color. Minerals are crystalline solids.
