Mica Biotite and Muscovite. In metamorphic rocks with a medium degree of metamorphism, it is very common for biotite to appear together with muscovite, both minerals make up the foliation of the rock and appear elongated. To differentiate them, biotite is easier to see in natural light where its pleochroism is the one that plays an …
Biotite is a mineral that's named after French physicist Jean Baptist who studied and researched about it for its optical properties. It is also known as Black Mica.
