Biotite distinguishing property
WebThe most distinguishing feature is color, with biotite mica being dark brown or black while muscovite mica is colorless to a very pale color. What is unique about muscovite? It is a combination of the pearly sheen, colorless to pale color, and perfect cleavage which makes muscovite unique among the minerals in the mica group. WebAs has already been described, igneous rocks are classified into four categories: felsic, intermediate, mafic, and ultramafic, based on either their chemistry or their mineral composition.
