| 摘 要： | NaCl- H2O-CO2体系流体是热液成矿系统中最常见的流体之一,针对该体系相关特征的研究对理解热液矿床的成矿机制和过程、成矿流体特征等具有重要的理论和实际意义.本文利用愈合人工水晶裂隙的技术,开展100 MPa、800℃条件下NaCl-H2 O-CO2体系流体的人工合成包裹体实验,并对其物理化学性质进行了初步探讨.通过对合成的包裹体进行岩相学观察、显微测温以及喇曼光谱分析,结果表明,在实验温压条件下合成的包裹体捕获了既定组成的流体;人工合成NaCl- H2O-CO2体系流体包裹体与天然流体包裹体具有相似的特征,可以作为天然包裹体的参照物应用于流体包裹体及地质流体的研究,特别是在评价CO2在热液矿床成矿过程中的作用方面,NaCl-H2O-CO2体系人工合成包裹体具有广阔的应用前景. |

| Abstract: | NaCl-H2O-CO2,a ternary fluid system,is one of the most common hydrothermal mineralization systems.Therefore,specific research on this system has theoretical and practical significances in understanding hydrothermal mineralization mechanism,processes and the characteristics of ore-forming fluids.By healing the artificial cracks in a crystal,this paper successfully synthesized the NaCl-H2O-CO2 system fluid inclusions at 100 MPa,800℃,and discussed their physical and chemical properties.Petrographic,microthermometric and Raman spectroscopic measurements were conducted on these synthetic fluid inclusions.The results showed that the synthetic fluid inclusions trapped the primary solution under the experimental condition.The physical and chemical characteristics of the synthetic fluid inclusions were consistent with the natural NaCl-H2O-CO2 system,and they can be used as a standard reference for the Geofluid and experimental geochemistry studies.They have a broad application prospects,especially in evaluating the role of CO2 in the formation of hydrothermal deposits. |
