作为一种重要的成矿元素,铜广泛分布于不同地质体中,并广泛参与成岩成矿作用.近年来,由于同位素分析方法的改进和新一代多接收等离子质谱仪(MC-ICPMS)的应用,使得铜同位素的高精度测试成为现实,并已成为国际地学领域的一个前沿研究方向.铜同位素在自然界中具有较大的变化范围,δ65Cu值介于-3.03‰～5.74‰之间.本文介绍和评述了铜同位素的分析方法和可能的分馏机制,并根据已发表数据,重点讨论了铜同位素组成与成矿温度、矿化阶段和成矿物质来源的关系.认为铜同位素有可能作为一种灵敏的地球化学示踪剂,对指示成矿物质来源、成矿作用过程和矿床形成机理具有重要作用. |

In recent years, copper isotope can be measured precisely thanks to the improvement of analytical methods and the use of MC-ICPMS, and hence this field has become a new frontier in earth sciences. Copper isotope shows considerable variation in nature (from ~3.03‰ to 5.74‰). This paper briefly describes and reviews the analytical methods and fractional mechanism of copper isotope. On the basis of data available, this paper focuses on the relationship between copper isotope composition and temperature, stages of mineralization and sources of ore-forming elements. As an important ore-forming element, copper exists widely in different geological systems and is active in ore-forming and rock-forming processes. Therefore, copper isotope may become a sensitive geochemical tracer and can play an important role in showing the sources of ore-forming elements as well as the ore-forming process and mechanism. |
