What is Mica?
Mica refers to a group of silicate minerals renowned for their remarkable ability to be split into thin, elastic sheets. This attribute, known as perfect basal cleavage, sets mica apart in the mineral kingdom.
Mica is typically easily identifiable from its thin sheet structure.
This feature arises from its unique crystal structure, where layers of silicon-oxygen tetrahedra are sandwiched between layers of metal ions, typically aluminum, iron, or magnesium.
These sheets are held together by weak van der Waals forces, which permit the layers to be easily separated.
Predominantly found in igneous and metamorphic rocks, mica occasionally appears in sedimentary rocks as well. It forms under a range of high-temperature conditions, commonly in granite and pegmatite, and also as a by-product of the alteration of minerals during metamorphism in schists.
