摘　　要：石英脉体中石英的气-液包裹体成分能反映其形成时的溶液性质.作者通过对几个有代表性石英脉型金矿床中石英气-液包裹体红外光谱特征的研究,提出包裹体中H_2O和CO_2的特征谱线强度可作为石英脉含金性的评价标志.Compositions of gas-fluid inclusions in quartz veins are able to reflect the properties of the solution produced. Through an investigation of infrared spectra of gas-fluid inclusions in some typical quartzvein type gold deposits, the author suggests that the intensity of characteristic spectra of H_2O and CO_2in the inclusions can be used as a mark for evaluating the ore potential of gold-bearing quartz veins.
