| 摘 要： | 山东玲珑九曲金矿床位于金矿田的东部，属石英脉--蚀变岩型金矿床，矿化分为4 个阶段，黄铁矿--石英脉阶段，石英--黄铁矿阶段，多金属硫化物阶段和石英--碳酸盐阶段。流体包裹体研究表明，九曲金矿床主成矿阶段石英中发育气液两相和含CO2 三相包裹体，也可见少量的富气相包裹体。气液两相包裹体均一温度范围为133. 5 ℃ ～ 325. 7 ℃，峰值为290 ℃ ～ 310 ℃，盐度为2. 80% ～ 17. 82% NaCl; 含CO2 三相包裹体均一温度范围为236. 5 ℃ ～ 315 ℃，出现两个峰值，为230 ℃ ～ 240 ℃和310 ℃ ～ 320 ℃，盐度为0. 41% ～ 8. 92%NaCl; 富气相包裹体均一温度范围为222. 1 ℃ ～ 236. 4 ℃，峰值为230 ℃ ～ 240 ℃，盐度为7. 71% ～ 9. 98%NaCl。综合地质条件、矿床特征和包裹体显微测温结果认为: 九曲金矿床成矿流体为中温、中低盐度的NaCl --H2O --CO2 型体系，矿床属中温岩浆热液成因类型。

| Abstract: | The Jiuqu gold deposit of Linglong is a quartz vein-altered type gold deposit． The mineralization process can be classified into four stages: pyrite-quartz phase，quartz-pyrite phase，polymetallic sulfides and quartz-carbonate phases． The study of fluid inclusion shows that aqueous two-phase，CO2-bearing three-phase and minor gas-rich fluid inclusions developed in quartz of the main mineralization in Jiuqu gold deposit． Fluid inclusion indicates that the aqueous two-phase homogenization temperature ranges from 133. 5 ℃ to 325. 7 ℃ with the peak value between 290 ℃ and 310 ℃，salinity varies from 2. 80% to 17. 82 % NaCl． The CO2-bearing three-phase homogenization temperature ranges from 236. 5 ℃ to 315 ℃ with two peak values as 230 ℃ ～ 240 ℃ and 310 ℃ ～ 320 ℃，salinity varies from 0. 41% to 8. 92%NaCl． The gas-rich fluid inclusion homogenization temperature ranges from 222. 1 ℃ to 236. 4 ℃ with the peak value between 230 ℃ and 240 ℃，salinity varies from 7. 71% to 9. 98%NaCl． Comprehensive study of ore-forming condition，geological features and microthermometic analysis of fluid inclusions leads to the conclusion that the ore-forming fluid of the Jiuqu gold deposit belongs to the NaCl--H2O --CO2 hydrothermal system with medium temperature and medium-low salinity． The deposit is middle-temperature magmatic and hydrothermal in origin． |
