摘要: 通过理论推导,提出了一种新的K-Ar、40Ar-39Ar等时线:40Ar/40K-36Ar/40K、40Ar/39Ar-36Ar/40Ar等时线。通过实例证明它与其它等时线方法可以进行相互检验。在一些不能利用其它等时线方法的情况下,新的40Ar/40K-36Ar/40K和40Ar/39Ar-36Ar/40Ar等时线方法可以充分显示它的使用价值和存在意义。

Abstract: A new K-Ar and 40Ar-39Ar isochron of 40Ar/40K-36Ar/40K、40Ar/39Ar-36Ar/ 39Ar isotope-correlation is proposed based on theoretical induction. Using examples proves that this kind of isochron can be confirmed each other with other isochrons. In some cases, such as other isochrons are not suitable, the new 40Ar/40K-36Ar/40K and 40Ar/39Ar-36Ar/39Ar isochron would indicate its value and significance. However, the difference between these three isochrons and their applicability need to be studied and discussed.
