| 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 +)-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 |
