Mineral Description
Biotite is a common rock forming mineral, being present in at least some percentage in most igneous and both regional and contact metamorphic rocks. Biotite mica is sometimes called iron mica because it is iron-rich. It is also sometimes called black mica as opposed to white mica (muscovite) both form in some rocks, in some instances side-by-side.

Sheets of biotite are flexible they can be bent and they go back to their original shape. Mica possesses great resistance to the passage of electricity and heat and is therefore used as an electronic insulator.

Biotite is also useful in assessing temperature histories of metamorphic rocks, because the partitioning of iron and magnesium between biotite and garnet is sensitive to temperature.
