WebBiotite is easy because it forms perfect shiny black cleavages and can be peeled into flakes. It can be confused with hornblene, but hornblende does not flake. Hornblende and augite are often confused. Most reliable is cleavage: hornblende forms ~120°/60° cleavages whereas augite forms ~90° cleavages. WebThat gives rise to the most characteristic feature of micas: perfect basal cleavage. As a result of that, biotite readily cleaves into parallel and flexible sheets.
