数值拟合法在修正K-Ar全岩年龄值方面的应用

Application of Numerical Value Inducation to Revise the K-Ar Isotopic Age

K Ar法是地质工作中常用的测年方法 ,根据测试对象的不同 ,可分为全岩以及单矿物K Ar法。通常情况下 ,前者的结果要比后者的结果偏低。本文在对华南及华北地区部分K Ar同位素年龄值进行详细分析的基础上 ,以黑云母年龄为基准值 ,采用数值拟合法 。

K-Ar Isotopic Age be applied to geological work. According to different object determined, can be divided into rock-age and single mineral-age. But rock-age is younger than single mineral-age. By in-depth analysis the K-Ar Isotopic Age of rock and single mineral, the paper take the K-Ar Isotopic Age of Bi as the cardinal number, and take the Numerical Value Inducation to Revise the K-Ar Isotopic Age of rock.
