FTP what is the common name for these minerals, including muscovite, that exhibit perfect cleavage?
This term actually refers to a group of thirty-four phyllosilicate minerals with similar chemical compositions, usually in di- or tri-octahedral forms. They often occur as irregular masses or as thin flakes in igneous rocks like pegmatites, but glauconite is found in sedimentary rocks on the ocean floor, and biotite is common in metamorphic rocks like schists. Consisting of cross-linked, double layers of silica tetrahedrons, almost all of them have a monoclinic crystal structure, explaining their best known property.
