摘　　要：Cu、Zn、Fe同位素示踪是近年来发展起来的一项新兴的同位素地球化学方法。本文介绍了用多接收电感耦合等离子体质谱 (MC ICPMS)精确测量铜、锌、铁同位素比值的方法 ,发现这些元素的同位素组成在不同地质与成矿环境中有明显变异 ,因而它们在矿床学、古海洋学和生物学等诸多领域具有广泛的应用前景。Cu, Zn, and Fe isotope methods are recently developed new geochemical tracers. In this paper, we introduce the analytical methods of MC-ICPMS to precisely determine Cu, Zn, and Fe isotopic ratios. It has been found that significant variations of Cu, Zn, and Fe isotopic compositions occur in various geological environments. Therefore these isotope methods will find their major applications in the fields of hydrothermal ore-forming processes, paleo-oceanography, and biological processes.
