摘要
通过野外观察和硫、碳、氧、氢同位素、微量元素和包裹体测定资料，对李家沟金矿床成矿物质的来源作了系统分析，证明金元素主要来自接官享组地层，硫来自地层，脉石碳酸盐矿物中的碳来自围岩硅质白云岩及碳质板岩，介质（水）主要来自变质水及地下热水。
Based on the field work and analysis of C,S, H,O isotopes and fiuid inclusions, the origin of ore - forming material of the li-jiagou gold deposit is systematically studied . lt is indicated that gold was derived from strata of Jieguanting Formation,sulfur from strata, andcarbon of carbonated from recrystalization and solution of silisic dolomite and carboniferous slate. Water was derived from metamorphic waterand underground water .
