| 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 ore s and ore-bearing rock series in the Jijiaogou gold deposit in Subei County, Gans u Province indicates that the deposit was formed in rift environment during post collision orogeny. The ore-forming matters were derived from mainly intermedia te-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 de posit genetically belongs to epithermal type related to magmatism. |
