Muscovite is a silicate material that contains potassium and aluminum. It is also known as Mica or Isinglass. Muscovite may form in layers of sheets ("Books") which are clear with a pearly luster on cleavage faces. Muscovite and Albite var Clevelandite Muscovite mica is a phyllosilicate mineral of aluminum and potassium with the formula KAl 2 (AlSi 3 O 10)(F,OH) 2, or (KF) 2 (Al 2 O 3)3(SiO 2)6(H 2 O). It has a highly-perfect basal cleavage yielding remarkably-thin laminae (sheets) which are often highly elastic.

Biaxial Minerals - Tulane University

Biaxial Positive. A mineral is biaxial positive if β is closer to α than to γ.; In this case the acute angle, 2V, between the optic axes is bisected by the γ refractive index direction. Thus we say that γ is the acute bisectrix (BX A), because it bisects this angle.; If a table of optical properties of minerals reports the 2V angle, it usually refers to this acute angle. This report is a preliminary evaluation of muscovite in the greisen as a commercial mineral resource. The study area includes parts of Nash and Wilson Counties.
