Definition

A hydrous silicate of aluminum and/or potassium that has crystallized into forms that allow perfect cleavage into very thin sheets (a phyllosilicate).

Description

Often used as dielectrics because of their resistance to electricity. Mica is a common mineral in many magmatic and metamorphic rocks and is often rock-building in metamorphic claystones like mica-schists. Based on their chemical composition and associated colour differences they are subdived into two groups: white mica (for example: muscovite) and dark mica (for example: biotite).
