ルミネッセンスおよびESR年代測定は，過去20年間にその測定技術が大きく進歩し，過去数十年から数百万年という広い範囲の，火山噴火，地層および堆積地形，考古遺跡，断層活動，岩石表面の露出の年代を決定できるようになった．これによって，地球科学や考古学の研究に大きく寄与したほか，最近では，山地の削剥隆起速度を求める熱年代学，河川や海岸の堆積物移動の定量，堆積物起源の推定といった，地球表層プロセスの解明への応用研究が進められている．本セッションでは，ルミネッセンスおよびESR年代測定の最新の技術の発展を踏まえ，これらの手法の基礎に関する研究，さまざまな地球表層プロセスの諸問題に対する応用研究など，第四紀年代学に資する研究発表を行う．関連分野との新たな連携を通じて，さらなる発展・普及を目指したい．

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.
