上宫金矿赋存在中元古界熊耳群安山岩和玄武岩中，矿体受断裂破碎带控制。含矿热液在迁移过程中，与围岩发生了强烈的流体－岩石反应，造成Ａｕ、Ａｇ、Ａｓ、Ｓｂ等成矿及其相关微量元素和Ａｌ２Ｏ３、ＴｉＯ２、Ｎａ２Ｏ等常量元素含量增加，稀土元素及其总量急剧减少。流体－岩石反应第一阶段发生的温度和压力条件为３６５℃～３００℃和２８５～２００ＭＰａ，而大量金沉淀成矿时的温度和压力范围则分别为３２５℃～２４０℃和１６０～１００ＭＰａ。成矿热液类型及其演化比较简单，从初始的低盐度（９．５％～６．３％ＮａＣｌ）、ＸＣＯ２为０．１８～０．２４的含ＣＯ２流体演化为低盐度（５．９％～１．６％ＮａＣｌ）的水溶液流体。流体－岩石反应是造成上宫金矿金沉淀成矿最主要的原因
The Shangong gold deposit is hosted in the Archean Xiong’er Group andesite and basalts, and the orebodies are controlled by the fault zone. During the process of migration, the ore-bearing hydrothermal fluid interacts strongly with the surrounding rocks, causing the formation of Au, Ag, As, Sb and other trace elements and the content of elements such as Al2O3, TiO2 and Na2O. The total amount of elements and their sharp decline. The temperature and pressure conditions in the first stage of fluid-rock reaction range from 365 ℃ to 300 ℃ and from 285 MPa to 200 MPa, while the temperature and pressure range for large amounts of gold deposits are 325 ° C to 240 ° C and 160 to 100 MPa, respectively. The types and evolution of mineralization hydrothermal fluids are relatively simple. From the initial low salinity (9.5% ~ 6.3% NaCl), the CO2-containing fluids with XCO2 of 0.18 ~ 0.24 evolve into low salinity (5 .9% ~ 1.6% NaCl) in water. Fluid-rock reaction is the most important reason for the gold deposits in the Shangong gold deposit
