摘要
本文通过对二道沟金矿床的地质特征、指示元素的垂直分带序列、地球化学异常分带模式、微量元素的垂直变化规律、石英包裹体测定的热晕特征、H2O和CO2的相对平均光密度的指示意义和黄铁矿的热电性等综合研究，指出二道沟金矿深部还有矿体存在。
By means of syntherical study of geological feature, vertical zoning sequence ofindicative elements, geochemical anomaly zoning medel, verical variability regularization of minorelements, thermal halo feature of quartz fluid inclusion companent distribution, relative averageoptical density of water and carbondioxide, and thermoclectricity of pyrites, we proope thatthere are deep - seated ore they under 600m level. It is estimated that deep - seated ore they maybe extend to 1000 m level, which should increase gold reserves.
