| 摘 要： | 新城金矿是胶东招远-莱州成矿带内重要的蚀变岩型金矿.流体包裹体研究表明,新城金矿蚀变岩石和各成矿阶段金矿石中的流体包裹体主要有3种类型:H2O-CO2包裹体、富CO2包裹体和H2O溶液包裹体.早期乳白色石英中主要赋存原生的H2O-CO2包裹体；成矿期黄铁矿石英脉中的富CO2包裹体主要为原生,随机分布,常与同时期的H2O...

| Abstract: | The Xincheng gold deposit is a typical altered rock type gold deposit in the Zhaoyuan-Laizhou gold ore belt of Jiaodong Peninsula,eastern China.Fluid inclusions in altered wall rocks and gold ores show that CO2-H2O-NaCl fluids have three main types,namely H2O-CO2,CO2-rich and aqueous inclusions.Early milky white quartz contains original H2O-CO2 inclusions.In the pyrite quartz vein,CO2-rich inclusions occur in isolation or cluster,whereas the aqueous inclusions occur as secondary trails in microfractures cut... |
