棚沟金矿床赋存于华北古陆块南缘前寒武纪花岗岩中，在空间上受区域韧性剪切带中的燕山末期花岗斑岩控制。根据矿床地质特点判断属中低温热液型金矿。通过岩石矿物组合及包裹体组成、性质、同位素等测试，确定成矿物质来源于围岩，成矿流体来源于变质水且有岩浆水与雨水的混入。通过电子探针测定的岩矿组分，计算围岩成岩及变质温度，以及成矿温度、压力和沉淀条件，认为金矿床的成矿作用，主要表现为减压环境中的岩浆热液充填和交代蚀变，以及热液的泡腾作用。从找矿标志角度确定富ＣＯ２的泡腾包裹体群、液相高硫富ＨＣＯ－３、气相高ＣＯ２和高ＣＯ２／Ｈ２Ｏ比值等参数是寻找此类金矿的重要标志
The Goupou gold deposit occurs in the Precambrian granite on the southern margin of North China paleosol block and is spatially controlled by late Yanshan granite porphyry in the region ductile shear zone. According to geological characteristics of the deposit to determine the genus of low-temperature hydrothermal gold mine. Through the mineral assemblages of rocks and the composition, nature and isotope of inclusions, it is confirmed that the ore-forming materials come from the surrounding rock, and the ore-forming fluid comes from the metamorphic water with the mixed magmatic water and rainwater. Based on the rock mass composition measured by the electronic probe, the diagenesis and metamorphic temperature of the surrounding rock are calculated, and the metallogenetic temperature, pressure and precipitation conditions are considered. The metallogenic effects of the gold deposit are mainly manifested by the magmatic hydrothermal filling in the decompression environment and Explain alteration, and hydrothermal effervescence. The determination of CO2-rich effervescent inclusions, the high-sulfur-rich HCO-3 in the liquid phase, the high CO2-to-CO2 ratio and high CO2 / H2O ratios from ore prospecting marks are important indicators for finding such gold deposits
