分子式:
CAS号:
性质:又称钾-氩法(potassium-argon age dating method)。根据岩石、矿物中40K经K层电子捕获,形成40Ar的衰变规律而建立的一种放射性同位素年代测定方法。计算年龄的公式为:T=1/λ ln(1+(1+R)/R·40Ar/40K);式中,λ=λK+λβ,R=λK/λβ、λK、λβ.分别为40K进行K层电子捕获和β衰变的衰变常数,40K、40Ar分别为这两种同位素的原子数。此方法可测定的年龄范围从太古代到新生代均可,但较古老样品如果具较复杂的演化历史,放射成因氩往往容易丢失,使测定的年龄偏年轻。最适合钾-氩法年龄测定的样品有云母、角闪石、海绿石、未脱玻化的玄武岩。
