摘要
具有明显分馏效应的硫同位素以各种含硫物种广泛赋存于热液成矿作用过程中,因此硫同位素示踪成为热液成矿作用研究的重要途径之一.在总结前人研究基础上,综述了硫同位素在热液成矿作用中成矿物理化学条件、成矿物质来源、矿体剥蚀程度、矿化富集部位、矿床成因类型等的示踪意义,认为硫同位素示踪应用须在了解热液矿床基础地质前提下,准确区分成矿期次,判别硫同位素分馏平衡状态,结合Ohmoto模式综合研究影响成矿热液体系的各种因素才可以赋予同位素准确的地质内涵.
The tracing of sulfur isotope is one of the significant methods in hydrothermal metallogenesis research for its broad existence in the hydrothermal metallogenesis with obvious fractionation. The application of sulfur isotope tracing involves the physical and chemical conditions, origin of ore-forming minerals, denudating degree of orebody, ore enriching position and genesis types of deposits. In the application, the geology of the hydrothermal deposit should be well understand to distinguish metallogenic epochs and judge the isotopic fractional equilibrium state, combined with the Ohmoto mode to study the factors possibly affecting hydrothermal fluid system.
