红外显微镜是研究不透明矿物中流体包裹体的重要手段,但红外光发热可能对不透明矿物中流体包裹体的盐度和均一温度测定有影响。本文以辉锑矿中流体包裹体为例,系统评价了红外光强度对测定辉锑矿中流体包裹体冰点的影响。结果表明,红外光强度对辉锑矿中流体包裹体的冰点测定有显著影响,导致过高估计流体包裹体的盐度,并提出了解决这一问题的方法。 |

Infrared microthermometry is useful for determining salinity and homogenization temperature of fluid inclusions in opaque minerals.Previous study showed that temperature of phase changes of fluid inclusion in opaque minerals varied with the infrared light source intensity,resulting in an overestimate of fluid salinities and an underestimate of homogenization temperatures.In this study,we evaluated the influence of infrared light source intensity on salinity of fluid inclusions in stibnite.The results reveal that the infrared light source intensity affects notably salinities of fluid inclusions in stibnite,resulting in an overestimate of fluid salinities. |
