摘要

为探讨夏甸金矿床成矿流体性质和来源,对该金矿-740~-820 m中段Ⅶ号矿体金矿石样品进行包裹体和S、H、O稳定同位素测定。夏甸金矿包裹体类型以富液体包裹体为主,其次为富气体包裹体和H2O-CO2三相包裹体,气液相比一般为10%~15%,VCO2LCO2LCO2LH2O相态占比较少;均一温度为72~342 ℃,主要集中在140~280 ℃之间,峰值为200 ℃;盐度[w(NaCl)]为0.5%~15.0%,主要集中在1.0%~7.0%之间;压力为61~541 MPa,平均压力为321.5 MPa;Ⅱ、Ⅲ成矿阶段的数据表明,夏甸金矿成矿温度、盐度和压力随着成矿阶段的推进而逐渐降低。包裹体物质成分主要为CO2、H2O和CH4δDH2O平均值为 -56.45‰,δOH2O平均值为11.67‰,变化范围窄,黄铁矿δ34SV-CDT值变化范围为+6‰~+8.1‰,平均值为 +7.04‰。富CO2包裹体、纯CO2包裹体和CO2-H2O包裹体是夏甸金矿床在主成矿期捕获的主要包裹体类型,而H2O溶液包裹体则主要出现在成矿晚期阶段,其成矿流体表现为温度中等、H2O-CO2-NaCl的较低盐度体系,并经历了流体相分离作用。H、O同位素特征表明主成矿期流体主要来自于壳源型花岗岩岩浆水,并有大气降水的加入,S同位素则指示硫源主要来自于胶东结晶基底岩系。

Abstract

Gold ore fluid inclusions and S, H and O stable isotopes from -740~-820 m middle section of ore body VII in Xiadian gold deposit were measured to study the ore-forming fluid properties and sources.The fluid inclusions are mainly liquid rich inclusions, followed by gas rich inclusions and H2O-CO2 three-phase inclusions. The gas-liquid ratio is generally 10~15, and VCO2LCO2 and LCO2LH2O phases are less. The average temperature is 72~342 ℃, mainly concentrated in 140~280 ℃, with a peak value of 200 ℃. The salinity of [w(NaCl)] is 0.5%~15.0%, mainly concentrated in 1.0%~7.0%. The pressure is 61~541 MPa, and the average value is 321.5 MPa. The data of Ⅱ and Ⅲ metallogenic stages indicate that the temperature, salinity and pressure of the Xiadian gold deposit decrease gradually with the change of the mineralization stage. The fluid inclusions are mainly composed of CO2, H2O and CH4. The average value of δDH2O is -56.45 ‰, and the average value of δOH2O is 11.67‰, with narrow range of variation. The range of pyrite δ34SV-CDT value is +6‰~ +8.1‰, and the average value is +7.04‰. The inclusions rich in CO2, pure CO2 and CO2-H2O are the main inclusion types captured in the main metallogenic stage of Xiadian gold deposit, while the inclusions of H2O solution mainly appear in the late stage of mineralization. The ore-forming fluid is characterized by medium temperature, low salinity system with H2O-CO2-NaCl, and has experienced fluid phase separation. The H-O isotopic characteristics show that the main metallogenic stage ore-forming fluid mainly comes from magmatic water of crustal granite, with the addition of atmospheric precipitation. The S isotopic characteristics indicate that the sulfur source mainly comes from the crystalline basement rock system in Jiaodong area.
