In nature, boron has two stable isotopes (¹⁰B and ¹¹B), usually δ¹¹B/10-3 values as the isotopic composition of geological bodys. As severe large fractionation between the two isotopes of ¹⁰B and ¹¹B in nature, high mobility of boron during both magmatic and fluid-related processes within a large temperature range takes place and lacks complexity associated with oxidation/reduction reactions, boron isotope has been developed in recent years as a powerful geochemical tool. The main factor of controlling boron isotope fractionation is the source of boron. Commonly, δ¹¹B of the non-marine borate minerals and tourmaline is of negative value and δ¹¹B of some salt lake and the marine minerals is positive.
