Trapped-Charge Dating (TCD) is a general term for absolute dating methods that use trapped electrons in crystal lattice, such as optically-stimulated luminescence (OSL) and electron spin resonance (ESR) dating. TCD presented one of the most successful progresses in geoscience and archaeology over the last 20 years, and still has a great potential in innovative applications. Technical progresses in optical dating of quartz and feldspar grains enables determination of depositional ages in a broad range from 10 to 500,000 years. Rock surface dating provides a way to determine surface exposure ages as well as burial ages of gravels. Thermochronometry with TCD is a state of the art method to determine the degradation and uplift rates on high temporal resolution. Further efforts have been made on TCD for extracting chronological information of past seismic activities. Innovative IRPL (infrared photoluminescence) method has also recently been invented. This session covers a wide range of TCD applications to problems in Quaternary geochronology as well as its technical advances. Comprehensive reviews on successful TCD applications and contributions of unestablished, challenging researches are also welcome.
