^(36)Ar/^(39)Ar-^(40)Ar/^(39)Ar等时线方法的应用——以新疆查汗萨拉锑、银矿带为例

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

等时线方法在K Ar年代学中得到广泛应用 ,本文利用一种新的3 6Ar 3 9Ar 4 0 Ar 3 9Ar等时线方法 ,计算查南疆汗萨拉锑、银矿带中石英脉的40 Ar 3 9Ar实验数据 ,并与其他等时线方法进行对比 ,得到非常一致的结果。

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.
