【摘要】 本文详细研究了察尔汗首采区卤水及其周边水源中的锂同位素组成,结果表明,察尔汗首采区平均δ~6Li值为-30.5‰,与海水的δ~6Li值相似,这样低的δ~6Li值与首采区卤水中发生的锂同位素分馏有关,且受具有低δ~6Li值的周边补给水的影响。更多还原

【Abstract】 The lithium isotopic compositions of brine and source water in the first exploitation area in Chaerhan have been studied. The results show that the average δ~6Li value for this area is—30.5‰, which is similar to that of sea water. The low δ~6Li value is relative to isotopic fractionation of lithium associated with lithium incorporation into clay minerials and isomorphous substitution between lithium and magnesium and affected by source water which has low δ~6Li values.更多还原
