Several descriptions of argon diffusion in K-feldspar have been developed, including the quantitative multiple-diffusion-domain (MDD) and multipath models and the qualitative 'recrystallization' model. These models remain contentious and the natural range in behaviour remains poorly understood. Feldspars from the Klokken syenite intrusion show a systematic relationship between 40Ar/39Ar age and microtexture suggesting that the loss of argon from different feldspars operates via different...[Show more]
