Biotite The Full Wiki

Biotite is a common phyllosilicate mineral within the mica group, with the approximate chemical formula K(Mg, Fe) 3 AlSi 3 O 10 (F, OH) 2. 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 endmembers include siderophyllite .
