Biotite

(after the French scientist J. B. Biot, 1774–1862), a mineral of the mica group. Biotite is structurally related to the micaceous aluminosilicates. Its chemical formula is K(Mg, Fe)₃AlSi₃O₁₀(OH,F)₂. The color of the thin sheets is from blackish-brown to brownish-green. Biotite occurs widely as a rock-forming mineral in igneous and metamorphic rocks. The largest biotite crystals, reaching 1–1.5 m, are found in pegmatite veins. Biotite is used in light-duty electrical insulating articles, and its powder is used in the preparation of bronze paint.,

biotite

[′bī·ə‚tīt] (mineralogy) A black, brown, or dark green, abundant and widely distributed species of rock-forming mineral in the mica group; its chemical composition is variable: K₂[Fe(II),Mg]_6-4[Fe(III),Al,Ti]_0-2(Si_6-5,Al_2-3)O_20-22(OH,F)_4-2. Also known as black mica; iron mica; magnesia mica; magnesium-iron mica.
