Trapped charge dating refers to two main Quaternary geochronology techniques, luminescence dating and electron spin resonance (ESR) dating, and both are based on the time-dependent storage of energy from natural radioactivity in crystal materials. Luminescence dating is commonly used to date the last time when quartz and feldspars in rocks or sediments were exposed to sunlight or heating, as well as the exposure age of rock surface. ESR is mainly applied to date biogenic materials such as fossil tooth, but can also be used to date quartz. Given its wide range in dating limit (ranging from a few years up to more than one million years) and target (quartz and feldspars, more than 70% of Earth’s crust), trapped charge dating has become one of the most important dating tools for studying earth and its inhabitants during the Quaternary period. The techniques have been successfully applied to various geological and geomorphological processes, such as aeolian, fluvial, alluvial and lacustrine deposits recorded paleoclimatic and paleoenvironmental changes, the provenance of sediments, tectonic activities, accumulation and erosion, and human evolution, etc.
This Research Topic provides an opportunity to present new advances in trapped charge dating applied to various contexts in East Asia, including but not limited to the reconstruction of geomorphology process, aeolian processes in deserts and sandy lands, dating of loess-aeolian sand-paleosol sequences to reconstruct the environmental change, rock exposure dating to reconstruct neo-tectonic activities, and human evolution and migration. We welcome new methodological studies, with a focus on improving accuracy, precision and extending dating range. New attempts to date unconventional materials, such as calcite, tufa, travertine and biogenic materials (such as phytolith, diatoms, snails, etc.) are especially welcome.
This Research Topic welcomes both original research and review articles. The research region should be related to trapped charge dating, while the Research Topic includes but is not limited to:
• Sediments dating and deposition patterns with their environmental/climate implications
• Quaternary lake-level variation and the mechanism
• Fluvial and alluvial deposits dating and geomorphological process
• Rock exposure dating and tectonic activities
• Advance in new dating techniques and their application
• Human migration and human activity
• Desertification and land surface erosion
