中文摘要:
      探讨了胶东大柳行金矿区矿床特征和成因,通过地质特征、成矿流体来源和物质来源等方面研究,对大柳行多个矿体进行样品采集工作,采用电子探针、光谱定量、流体包裹体、硫碳氢氧同位素等分析方法,认为大柳行金矿床可划分为3个成矿阶段;成矿流体为大气水和岩浆水的混合物;具有富H2O、富CO2流体特征;成矿物质可能主要为地幔来源,混合有大气降水;具壳幔混源特征。属于低盐度、低密度、中低温、中深成矿床。
英文摘要:
      This paper discusses the characteristics and genesis of Daliuhang gold deposit in Jiaodong. The samples from several ore bodies of Daliuhang are collected and analyzed by electron microprobe, spectral quantification, fluid inclusions, and sulfur-carbon-hydrogen-oxygen isotopes from the aspects of geological characteristics, ore-forming fluid sources and material sources. It is considered that the Daliuhang gold deposit can be divided into three metallogenic stages. The ore-forming fluid is a mixture of meteoric water and magmatic water, rich in H2O and CO2.The ore-forming material may mainly derive from mantle, mixed with meteoric water and characterized by mixed crust mantle source. Daliuhang gold deposit belongs to medium plutonic deposits with low salinity, low density, and medium-low temperature.
