Hornblende Schist

Hornblende, like other members of the amphibole group, is a common rock-forming mineral. In fact, hornblende is the most prevalent of all the amphiboles. It is widely distributed in igneous and metamorphic rocks, such as schists. Calcium-rich and monoclinic, hornblende displays the characteristic amphibole structure, which involves four metal sites located between double tetrahedral chains.
