流体包裹体中流体的同位素组成 ,广泛应用在推测流体来源及确定流体成矿年龄方面。由于流体包裹体一般是多成因及多期的 ,在用流体同位素研究成矿流体时 ,需要注意到流体包裹体的捕获是否与成矿同期。本文主要以 Rb- Sr同位素为例探讨了流体包裹体同位素在成矿流体来源及确定成矿年代方面的意义。
The fluid isotope composition of fluid inclusions is widely used to infer the source of fluids and determine the age of fluid mineralization. Since fluid inclusions are generally multi-generative and multistage, it is important to note whether the fluid inclusions are trapped during the ore-forming phase when studying fluid-forming fluids with fluid isotopes. This paper mainly discusses the significance of isotopes of fluid inclusions in the source of ore-forming fluid and determination of metallogenic age by taking Rb-Sr isotope as an example.
