Biotite | Revolvy

Biotite Biotite is a common phyllosilicate mineral within the mica group, with the approximate chemical formula K(Mg,Fe)AlSiO(F,OH). More generally, it refers to the dark mica series, primarily a solid-solution series between the iron-endmember annite, and the magnesium-endmember phlogopite; more aluminous end-members include siderophyllite.

Discover Mica Minerals - ThoughtCo

The mica minerals are distinguished by their perfect basal cleavage, which means that they are easily split into thin, often transparent, sheets. Two micas, biotite, and muscovite, are so common that they are considered rock-forming minerals. The rest are relatively uncommon, but phlogopite is the ...

University of Minnesota's Mineral Pages: Amphibole

In igneous rocks, amphibole minerals are usually associated with the intermediate feldspar minerals, while in metamorphic rocks they are associated with mica minerals. In metamorphic rocks, amphibole minerals may themselves be altered into other iron-magnesium silicates such as chlorite, epidote and biotite.

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.
