After skating primarily in Northern California, a Midwest tour was launched in , but flopped due to competition from baseball and football as well as weather-related problems.
On the applicability of post-IR IRSL dating to Japanese loess
Quartz has been the main mineral used for optically stimulated luminescence OSL dating of sediments over the last decade. The application of IRSL dating of feldspars, however, has long been hampered by the anomalous fading effect. These procedures have raised the prospect of isolating a non-fading IRSL component for dating Quaternary deposits containing feldspars. In this study, we review the recent progress made on 1 overcoming anomalous fading of feldspar, and 2 the development of pIRIR dating techniques for feldspar.
