    The minerals kyanite, Adalusite and sillimanite are polymorphs of Al2SiO5, each like a bunch of fibres twisted together when viewed in thin section or even by the naked eye.

    Optical properties: Cleavage: () perfect: thus a basal section of sillimanite, wichh is diamond shaped, has cleavage parallel to the long axis. 85° (D), sillimanite is either fibrous or elongate prismaBc with almost square Staurolite - Optical Properties Fe 2 Al 9 O 6 (SiO 4) 4 (OH) 2 monoclinic n α Staurolite in Thinsection PPL: yellow pleochroic, medium high relief XPL: 1 st order.

    Optical properties As summarized in Tablesillimanite is characterized by are particularly diagnostic because of the nearly square shape [()^() Due to low transition element contents, most sillimanite is colorless in thin section​.

    low-pressure polymorph, kyanite stable at high pressures, and sillimanite stable at of carbonaceous matter on the edges of the nearly square cross-section.

    Sillimanite Mineral information, data and localities.

    In thin section, the mineral has a low birefringence, a medium relief, and a high 2V (-). Its optical properties include an orthorhombic crystal form, a second-​order. Andalusite is an aluminium nesosilicate mineral with the chemical formula Al2​SiO5.
