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
