Application of New ~(36)Ar/~(39)Ar-~( 40)Ar/~(39)Ar Isochron Method──Exampled by Chahansala Sb-Ag Ore Belt in Southern Xinjiang

Isochron analysis method has been used widely in K-Ar and Ar-Ar geochronology. A new 36Ar/ 39Ar- 40Ar/ 39Ar isochrone method be used to calculate the 40Ar- 39Ar data of Chahansala Sb-Ag ore belt in south Xinjiang in this paper .The result is uniform with traditional isochron method.
