| 摘 要： | The Wendeng gold deposit is located 30 km northwest of Wendeng City,Shandong Province, occurring in a brecciated alteration zone in the foot wall of the NNE-striking fault(F1). It consists of quartz, pyrite, specularite, potash feldspar, sericite, carbonates and chlorite hosted in Proterozoic biotite-plagioclasee gneiss. Three generations of quartz are recognized based on cathodoluminescence and micro morphology. Systematic studies of fluid inclusions provide data to establish P-T-V-X relations for the fluid evolution in mineralization process.It is concluded that the ore-forming solution was evolved from meteoric water through ghermal events during Mesozoic tectonics. The precipitation of gold was related to two boiling events.

| Abstract: | The Wendeng gold deposit is located 30 km northwest of Wendeng City, Shandong Province, occurring in a brecciated alteration
zone in the foot wall of the NNE-striking fault(F1). It consists of quartz, pyrite, specularite, potash feldspar, sericite,
carbonates and chlorite hosted in Proterozoic biotite-plagioclasee gneiss.
Three generations of quartz are recognized based on cathodoluminescence and micro morphology. Systematic studies of fluid
inclusions provide data to establish P-T-V-X relations for the fluid evolution in mineralization process. It is concluded
that the oreforming solution was evolved from meteoric water through thermal events during Mesozoic tectonics. The precipitation
of gold was related to two boiling events. |
