In all three rock types: igneous, sedimentary, and metamorphic. By definition, a mineral has a crystalline structure, and rocks are composed of combinations of minerals. Rocks with interlocking crystalline mineral structures are usually igneous or metamorphic.

Minerals are naturally occurring inorganic substances with a specific chemical composition and crystalline structure. While they are primarily found in nature, some minerals can be synthesized in a laboratory setting to mimic their natural counterparts.


Do all minerals have crystalline structures?

No, not all minerals have crystalline structures. Some minerals, called amorphous minerals, do not have a regular crystalline structure and instead have a disordered atomic arrangement. Examples of amorphous minerals include opal and glass.


Are all minerals crystalline?

A mineral, by definition is an inorganic solid with a crystalline structure formed naturally. Wood, paper, or any other organic solids are not minerals because they have no crystalline structure and form organically. Plastic is not a mineral either because it is made synthetically out of organic materials. Some organic materials like coal and other hydrocarbons are considered minerals economically. Bones and teeth contain hydoxylapatite that is organically formed but is still considered a mineral, so there are exceptions. Whewellite is organically formed but has a crystalline structure, and is considered a mineral.
