硼、氯同位素测定方法及地球化学研究进展

近十年来，由于高精度硼、氯同位素测定方法的建立，硼、氯同位素地球化学在研究的深度和广度上都得到了快速发展。硼、氯同位素地球化学的研究已在海洋、盐湖、地下水、蒸发岩、热液矿床、环境等方面开展，并显示出在解决一些地学问题方面所具有的良好前景。该文简要概述了目前国内外硼、氯同位素测定方法和在地球科学的一些领域应用方面取得的成果和进展。

BORON AND CHLORINE ISOTOPIC DETERMINATIONS AND APPLICATIONS FOR EARTH SCIENCES

    Boron has two stable isotopes (¹¹B and ¹⁰B), chlorine also has two stable isotopes (³⁷Cl and ³⁵Cl). The large different in mass ( 11 and 10, 35 and 37) make both boron and chlorine exist big isotopic fractionation in the nature. Variations of boron and chlorine isotopic compositions had not been found in early investigations due to poor precision of determing boron and chlorine. Since 1980s, with some high precise methods of determing boron and chlorine isotopes, the variations of boron and chlorine isotopes in nature have been evidenced by high precise determination and a lot of investigations. δ¹¹B range from -30‰ to 60‰, and δ³⁷Cl range from -2‰ to 7‰.
    Many significant work about boron and chlorine isotopic geochemistry have been maken in oceans, salt lakes, groundwater, evaporated sediment and hydrothermal fluids. This paper give a brief summary of including analytical methods and application in Earth sciences.
