摘要
西天山阿希金矿含金石英脉内流体包裹体粒度细小，形态多样，以单一液相为主．化学成分上属Ｋ＋（Ｎａ＋）－ＳＯ２－４（Ｃｌ－）型，其中阳离子成分以Ｋ＋为主，Ｎａ＋次之；阴离子成分以ＳＯ２－４为主，Ｃｌ－次之；气相成分以Ｈ２Ｏ、ＣＯ２为主，富含Ｏ２、Ｎ２等气体，还原性气体（Ｈ２、ＣＨ４、ＣＯ等）含量亦较高．成矿作用发生于浅成（３００～９００ｍ）、低温（１２０～１８０℃）和较封闭的还原环境．成矿流体盐度低，主要为大气降水并混以少量火山成因的岩浆水．
The fluid inclusions of Axi gold deposit are characterized by fine size,various shapes and mostly single liquid facies They chemically belong to K +(Na +)-SO 2- 4(Cl -)type K + is the major part in cations while SO 2- 4 is the counterpart in anions H 2O and CO 2 are the major components in gas facies with rich O 2,N 2 and reduced gases(H 2,CH 4,CO,etc ) The ore forming process took place in low temporature (120～180℃),shallow seated (300～900m) and reduced evironment with low salinity fluid which is majorly atmospheric water mixed with minor volcanic origin magmatic water
