  • Staurolite: A metamorphic mineral famous for twinned crystals

    翻译此页Staurolite is a mineral that is commonly found in metamorphic rocks such as schist and gneiss. It forms when shale is strongly altered by regional metamorphism. It is often found in association with almandine garnet, muscovite, and kyanite minerals that form under similar temperature and pressure conditions.Chemistry

  • Staurolite: The mineral staurolite information and pictures

    The Mineral staurolite Staurolite is best known for its distinctive, cross-shaped penetration twin s, where two rectangular crystals intersect each other to form a perfect cross. However, its most common twinning habit is in bisecting crystals with a 60° angle that can appear in the shape of an "x" when the crystals are elongated.Онлайн-запрос
