WebAs nouns the difference between biotite and phlogopite. is that biotite is a dark brown mica; it is a mixed aluminosilicate and fluoride of potassium, magnesium and iron while phlogopite is a mica mineral with the chemical formula KMg 3 AlSi 3 O 10 (F,OH) 2, a basic potassium magnesium aluminosilicate, used as an insulator. WebIn a fairly common intermediate stage, weathered biotite is golden yellow, has a bronzy lustre, and may be mistaken by inexperienced observers as flakes of gold. Phlogopite is rare in igneous rocks; it does, however, occur in some ultramafic (silica-poor) rocks. For example, it occurs in some peridotites, especially those called kimberlites ...
