Lithium Isotope Geochemical Research Progress

Lithium has two stable isotopes(6Li and 7Li)with great mass difference.Hence,Lithium istope fractionation is significant.Due to the improvement of analysing and measuring technology,lithium isotope geochemistry has been developing rapidly.Researches have shown that temperature is a key factor which control lithium isotope fractionation.In addition,The difference of lithium coordination in different minerals and bond strength can also affect lithium isotope fractionation.Larger isotope fractionation and different lithium isotopic values in geological reservoirs make lithium isotope geological application very extensive.Up to now,lithium isotope research has made great achievements in continetal weathering,submarine hydrothermal solution and oceanic crust altering,plates subduction and brine origin and evolution tracing.Furthermore,lithium isotope has been applied to deposit research.
