Flake mica comes from several sources: the metamorphic rock called schist as a byproduct of processing feldspar and kaolin resources, from placer deposits, and from pegmatites. Sheet mica is considerably less abundant than flake and scrap mica, and is occasionallymica | Structure, Properties, Occurrence, & Facts,,Mica: 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.Mica | Minerals Education Coalition,Mica is a mineral name given to a group of minerals that are physically and chemically similar. They are all silicate minerals, known as sheet silicates because they form in distinct layers. Micas are fairly light and relatively soft, and the sheets and flakes of mica are flexible.The Mica Group of Silicate Minerals - Rocks and Minerals,,The Mica Group Mica is the name given to a group of silicate minerals that have silicon and oxygen as their two major components.

Muscovite may form in layers of sheets (calledUSGS Minerals Information: Mica,The mica group represents 37 phyllosilicate minerals that have a layered or platy texture. The commercially important micas are muscovite and phlogopite. Layering in the univalent (potassium, sodium), or true, micas imparts perfect basal cleavage, allowing crystals to be split into very thin sheets that are tough and flexible.
