Physical properties. The rockforming micas (other than glauconite) can be divided into two groups: those that are lightcoloured (muscovite, paragonite, and lepidolite) and those that are darkcoloured (biotite and phlogopite).

Anisotropic minerals go extinct every 90° of stage rotation. Many minerals show characteristic optical properties in relation to their form, cleavage, twin plane or exsolution planes. In particular, the angle made between extinction and a prominent lineation is called the extinction angle.

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. It was named by Hausmann in 1847 in honor of the French physicist JeanBaptiste Biot who, in 1816, researched the optical properties of mica, discovering many unique properties.

The arrangement and relationships between minerals in soils is probably more complex than that found in most rocks since many types of mineral and their weathered products can occur in juxtaposition. Therefore it is essential to give an account of the optical properties of the principal minerals in soil including those derived from the parent ...
