K-Ar and Ar-Ar Dating

Reviews in Mineralogy and Geochemistry, 2002
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 Ar-Ar 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 ...

Excess argon in K–Ar and Ar–Ar geochronology

Chemical Geology, 2002
The K–Ar and Ar–Ar dating techniques occasionally produce anomalously old ages attributed to excess argon, and such data is often rejected as not offering any insight into the age, thermal history or geochemistry of the rock. However, improvements in the quantification of argon geochemistry now provide a framework to model excess argon in both open and
