摘　　要：通过对辽宁西部火山岩型金矿床流体包裹体研究，讨论了该区火山岩型金矿的成矿作用。辽西地区火山岩型金矿具有中低温热液和低ＣＯ２、高Ｋ＋特点。成矿溶液以岩浆水为主兼有天水地下渗流混合特征。结合成矿地质条件，阐述了火山岩型金矿成矿热液演化过程。Based on the study of fluid inclusions in the volcanic gold deposits in the west of Liaoning province, the gold mineralization of this area is discussed. The volcanic gold deposits in the area have features of media low temperature fluid and low CO 2 , high K +. The ore forming fluid is maily from magmatic solution mixed with groudwater. With the geological condition of the deposits, the evolution of the hydrothermal fluid is illustrated in the article.
