Pericline is a term that can refer to a specific type of mineral, known as a variety of the mineral clinopyroxene. In a broader context, pericline can also denote a specific type of twinning in minerals, particularly feldspar. In crystallography, pericline twinning involves a specific orientation of crystal structure that can result in distinctive growth patterns and optical properties.
