Staurolite is a mineral that typically forms in metamorphic rocks, particularly in medium to high-grade metamorphic environments. It is characterized by its complex silicate structure, which includes aluminum, iron, magnesium, and zinc, contributing to its varied composition. Staurolite commonly appears as brown to black, prismatic crystals that often exhibit a distinctive cross-shaped twinning, which is a notable feature of the mineral. Its hardness ranges from 7 to 7.5 on the Mohs scale, making it relatively hard compared to other minerals. Staurolite is also recognized for its high specific gravity and is often used as an indicator mineral in metamorphic studies. The presence of hydroxyl groups in its structure contributes to its stability under varying temperature and pressure conditions. Additionally, staurolite can be found in various geological settings, including schists and gneisses, and is sometimes associated with other minerals such as garnet and kyanite. Its unique properties make it of interest not only in geology but also in the study of metamorphic processes.
