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.

Abstract: 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+)-SO2-4(Cl-)type K+ is the major part in cations while SO2-4 is the counterpart in anions H2O and CO2 are the major components in gas facies with rich O2,N2 and reduced gases(H2,CH4,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
