Tourmaline, which is a borosilicate, is the main source of boron found in soil. It is a mixture of silicates and borates from where boron is extracted. It is available as a complex cyclosilicate, Al6Y3Na[Si6O18](BO3)3(OHF)4, with Y = Mg, Fe, Mn or Li. The rhombohedral system has the shape of an elongated rod or needle type prism. Tourmaline is used as a gemstone, and because of its double refraction and piezo-electric properties, it is used in polarizers and in some pressure gauges. The best known variety of tourmaline is black tourmaline which is rich in iron and is a common mineral in igneous and metamorphic rocks. Magnesium-rich tourmaline is called dravite. Lithium-rich varieties are called elbaite. Ferruginous varieties are called schorlite which is insoluble in water and resistant to weathering and hence releases boron slowly.
