摘　　要：近年来,随着多接收器电感耦合等离子体质谱仪(MC-ICP-MS)的广泛应用和测试精度的不断提高,非传统稳定同位素成为同位素地球化学最前沿和最活跃的研究领域。其中钼同位素作为非传统稳定同位素发展较为成熟的方向之一,已经逐步应用到地球科学、生命科学、环境科学等各个重要领域,并取得了长足的发展。本文对近些年国内外所取得的钼同位素研究成果进行了系统整理、总结,并对钼同位素的应用潜力进行了概括性的综述,主要包括钼元素及其同位素的地球化学特征、钼同位素分析测试技术、钼同位素的分馏机制、不同地球化学储库的钼同位素组成、成矿作用过程中钼同位素组成的变化特征及其在矿床中的应用。以期让更多人了解钼同位素这一非传统稳定同位素的最新研究进展,进一步探索成矿作用过程中钼同位素的组成特征、分馏机制和影响因素等,并有效推动钼同位素地球化学在成矿作用研究方面的应用。With the wide application of multi-collector inductively coupled plasma mass spectrometry (MC-ICP-MS) and the improvement of testing accuracy, non-traditional stable isotopes have emerged at the forefront of the active research field of isotope geochemistry. The analysis of molybdenum (Mo) isotopes in particular is one of the most mature techniques based on non-traditional stable isotopes, and it has been applied with great success to many important fields, such as earth and life sciences. In order to introduce the latest advances of Mo isotope geochemistry based on a large number of documents and data, this paper summarizes the rationale behind Mo isotope geochemistry and its application in ore deposits, which mainly includes the geochemical characteristics of Mo and its isotopes, Mo isotope analysis and testing technology, Mo isotope fractionation mechanism, Mo isotope composition in different geochemical reservoirs, the variation in characteristics of Mo isotope composition in the ore-forming process and their application in ore deposits. To promote the application of Mo isotope geochemistry in the study of mineralization, we propose that geochemists and economic geologists be involved in the exploration of Mo isotope composition, Mo isotope fractionation mechanism and influencing factors in the ore-forming process.
