中文摘要：

八卦庙金矿床是赋存于热水沉积岩系中,并受二里河—八卦庙脆-韧性剪切带构造控制的大型金矿床,矿体严格产出在2期石英脉中及其附近。通过对矿区内2期石英脉的研究,将成矿期次初步划分为（早期）NW向石英脉成矿期、（晚期）NE向石英脉成矿期,早期成矿于190-230 Ma,晚期集中在125-130 Ma。综合研究认为,八卦庙金矿床成因类型应为热水沉积-改造型金矿床。

英文摘要：

Baguamiao Gold Deposit occurs in the hydrothermal - sedimentary rocks and is a large scale gold de- posit controlled by the Erlihe - Baguamiao brittle-ductile shear zone. The ore output is confined in the two quartz veins and their vicinity strictly. Based on the research of the two quartz veins, the metallogenic stages are classified into NW quartz vein mineralization （ early stage） and NE quartz vein mineralization （ late stage）. The early mineralization was formed between 190 -230 Ma, and the late between 125 - 130 Ma. By analyzing the type of deposit, the paper takes that the Baguamiao is hydrothermal - sedimentary transformation type gold deposit.
