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。
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.
