摘要鸡叫沟金矿床矿石及含矿岩系的稳定同位素、流体包裹体及稀土元素等地球化学研究表明，金矿床形成于碰撞造山运动后期的裂谷环境，成矿物质主要来自中基性、超基性火山岩，为低温、低盐、浅成的金矿床.硫来自岩浆硫.矿物质水主要来自大气降水，后期又萃取了岩浆水.矿床类型为与岩浆作用有关的浅成低温热液型.

Abstract：Study on the stable isotope, fluid inclusions and REEs for the ores and ore-bearing rock series in the Jijiaogou gold deposit in Subei County, Gansu Province indicates that the deposit was formed in rift environment during post collision orogeny. The ore-forming matters were derived from mainly intermediate-basic to ultrabasic volcanic rocks. It is an epithermal deposit with low-te mperature and low-salinity. The sulfur is magma-derived. The mineral fluid is dominantly from atmospheric water and later extraction of magmatic water. The deposit genetically belongs to epithermal type related to magmatism.

Key words： geochemistry of deposit genesis gold deposit Subei County
