[H-QR06] Luminescence and ESR: Applications to Dating and Earth Surface Processes

Tue. May 26, 2026 9:00 AM - 10:30 AM Exhibition Hall Special Setting (2) (Exhibition Hall 7&8, Makuhari Messe)

Chairperson:Tamura Toru(Institute of Geology and Geoinformation Geological Survey of Japan, AIST), Ogata Manabu(Tono Geoscience Center, Japan Atomic Energy Agency)

Over the past two decades, luminescence and electron spin resonance (ESR) dating have made remarkable advances, enabling accurate age determinations from several decades to several million years. These techniques have contributed greatly to geoscience and archaeology by providing ages of volcanic eruptions, stratigraphy, sedimentary landforms, archaeological sites, fault activity, and rock-surface exposure. More recently, luminescence and ESR dating have been extensively applied to studies of earth surface processes, including low-temperature thermochronometry for assessing mountain denudation and uplift rates, quantification of sediment transport in fluvial and coastal systems, and provenance analysis of sediments. These developments demonstrate the growing potential of luminescence and ESR measurements as powerful tools not only in Quaternary geochronology but also in understanding dynamic earth surface processes. Based on these technical advances, this session will showcase recent progress in both fundamental research and innovative applications of luminescence and ESR measurements. We welcome contributions addressing methodological developments as well as applications to a broad range of geological and environmental problems. By bringing together researchers from related disciplines, we aim to foster new collaborations and promote further advances and wider dissemination of luminescence and ESR techniques.
