Biotite Mica - Mineral and Healing Properties

Biotite Mica Biotite is a common rock forming mineral, being present in at least some percentage in most igneous and both regional and contact metamorphic rocks. The typical black to brown color of biotite is characteristic although it is difficult to distinguish brown biotite from dark brown phlogopite.

University of Minnesota's Mineral Pages: Biotite

Biotite and phlogopite are easily recognized as mica minerals, because of their perfect single cleavage and the ease with which they are separated into thin flexible sheets. Color is the only easy way to distinguish them from one another and other micas like muscovite.

What is the difference between biotite and muscovite minerals?

Biotite is a "brown" mica group incorporating Mg and Fe. Given their chemical differences you find them in different rocks. As you would expect, white mica would be found in light-coloured felsic rocks, dark mica in Fe/Mg-rich dark, mafic rocks (or in their weathering products).
