Muscovite is another common mica mineral that has a single perfect cleavage similar to biotite and phlogopite. It also occurs in the same igneous and metamorphic rocks that biotite is found in. However, muscovite is much lighter in color than biotite, typically being colorless to white.
The commercially important micas are muscovite and phlogopite, which are used in a variety of applications. Micaâs value is based on several of its unique physical properties. The crystalline structure of mica forms layers that can be split or delaminated into thin sheets usually causing foliation in rocks.round mica is used in the well-drilling industry as an additive to drilling fluids. The coarsely ground mica flakes help prevent the loss of circulation by sealing porous sections of the drill hole. Well drilling muds accounted for 15% of dry-ground mica use in 2008.
