Review on K-Ar Dating Method

K-Ar and Ar-Ar Dating

The aim of this chapter is to present the K-Ar and Ar-Ar dating techniques in the context of noble gas studies, since there are already several recent texts on K-Ar and ArAr dating (Dickin 1995; McDougall and Harrison 1999). The focus of this section will be aspects of argon transport and storage in the crust, which affect K-Ar and Ar-Ar dating including Ar-loss from minerals by diffusion and A...

Ar-ar Dating of Thermal Events on Meteorite Parent Bodies

Parent bodies of meteorites have experienced a variety of thermal events caused by early internal metamorphism and impact heating. Among radiometric chronometers, the 39 Ar-40 Ar technique is particularly sensitive to such thermal events. For over two decades the JSC laboratory has acquired 39 Ar-40 Ar data on a wide variety of meteorite types. The purpose here is to summarize some JSC data (an...

Evaluation of the Ar/Ar Dating Process

During the last half of the twentieth century, the argon-argon method of dating geologic rocks and formations became very popular. This method replaced K/Ar as the method of choice for many types of rocks. This paper explores the fundamental mathematics of the argon-argon dating method and evaluates the impact of the assumed date of the “standard sample” on the calculated argon-argon date. A me...
