| 中文摘要:太行山金矿中流体包裹体的显微红外光谱研究表明，金矿成矿流体的化学组成从简单的H2O+NaCl、H2O+ CO2、H2O+ CO2+ NaCl到复杂的H2O+ CO2+ NaCl+H2S+CH 4和CO2+ CH4和H2O+NaCl体系。首次在太行山金矿的单个流体包裹体中检测到H2S和CH4谱峰对探讨该区成矿流体的演化具有重要理论意义。金矿中存在3类物理性质和化学性质截然不同的流体包裹体，同一样品中几乎同时出现物理性质和化学性质完全不同的两类甚至三类流体包裹体，说明在流体包裹体被捕获的环境中，存在相互不混溶的两种或3种流体，并且这些不混溶流体处于强烈的动荡状态中。 |

| Abstract:Three kinds of fluid inclusions were studied by using micro FTIR. The results show that the gold-forming fluids evolved chemically from simple H2O+ NaCl H2O+ CO2 and H2O+CO2+ NaCl to complex H2O+ NaCl+ CO2+ H2O+ CH4 and CO2+ CH4+ H2O+ NaCl systems. This paper reports for the first time the presence of H2S and CH4 in the ore-forming fluids in the Taihang Mountains, which is significant in the study of the mineralization in this area. There are three physically different fluid inclusions in the gold deposits. The existence of such different fluid inclusions in the same sample suggests that there exist three kinds of unmixed or coexistent fluids in the environments where the inclusions were trapped, and these unmixed fluids were violently variable. |
