| 摘 要： | 论文通过对碱泉子金矿床和文峪金矿床成矿地质背景的认识,得出了两矿床的矿床地质特征都显示了明显的造山型热液金矿床的矿床地质特点。在此基础上对比研究了两矿床的流体包裹体特征及氢氧同位素组成特征。研究结果表明,两矿床的成矿流体均以中温、低盐度、高CO2含量为特征,这些特征也吻合了典型的造山型热液金矿床成矿流体的基本特征;两矿床氢氧同位素组成的数据投影点主要落在变质水与岩浆水的混合区附近、并有向大气降水漂移的趋势。基于以上分析结果,推断出两矿床在成矿机制方面也有很大的相似性,并由此探讨了碱泉子金矿床的成矿机制特点。

| Abstract: | The researches on the metallogenic geological settings of the Jianquanzi gold deposit and Wenyu gold deposit show that they both have geological characteristics of orogenic hydrothermal gold deposits.On this basis,the characteristics of fluid inclusions as well as hydrogen and oxygen isotope compositions are analyzed and compared.It is found that the ore-forming fluids are characterized by medium temperature,low salinity and rich CO2,which accords with the characteristics of the fluid inclusions at typical ... |
