Review:
Biotite Mica
overall review score: 4.2
⭐⭐⭐⭐⭐
score is between 0 and 5
Biotite-mica is a common silicate mineral belonging to the mica group. It is characterized by its thin, sheet-like crystal structure that allows it to be easily cleaved into flexible, transparent sheets. Typically dark brown to black in color, biotite is a vital component in metamorphic and igneous rocks and is valued both for its physical properties and its use in geological studies.
