Mica mineral: Mica is a naturally occurring mineral known

Mica is a naturally occurring mineral known for its unique physical properties, including its ability to split into thin, flexible sheets. This versatility makes mica invaluable across various industries, from electronics to cosmetics. The global distribution and mining of mica reflects its widespread industrial use. Mica deposits are found in significant quantities across different continents, emphasizing its role in economic and industrial developments worldwide. Understanding the origins ... Mica is the term for a large group of sheet silicates that can be parted into flexible or brittle sheets. Includes the True Micas or Common Micas (with monovalent interlayer cations, e.g. muscovite, paragonite, ephesite) and the Brittle Mica s (with divalent interlayer cations, e.g. margarite, clintonite). Also known as the " mica family". Mica, any of a group of hydrous potassium, aluminum silicate minerals . It is a type of phyllosilicate, exhibiting a two-dimensional sheet or layer structure. Among the principal rock-forming minerals , micas are found in all three major rock varieties—igneous, sedimentary, and metamorphic. The micas include several notable mineral species including black mica , margarite, celadonite, and sericite.
