Reducing variability in OSL rock surface dating profiles
Quaternary Geochronology, 2021 Abstract In recent years, rock surface dating has seen the emergence of a technique based on optically stimulated luminescence (OSL). This application translates the depth of OSL signal bleaching within a rock surface into an exposure age or erosion rate at 1-104 a timescales.

Single-grain TT-OSL bleaching characteristics: Insights from modern analogues and OSL dating comparisons [PDF]
Quaternary Geochronology, 2019 Previous assessments of thermally transferred optically stimulated luminescence (TT-OSL) signal resetting in natural sedimentary settings have been based on relatively limited numbers of observations, and have been conducted primarily at the multi-grain scale of equivalent dose (De) analysis.

Evaluating optically stimulated luminescence rock surface exposure dating as a novel approach for reconstructing coastal boulder movement on decadal to centennial timescales [PDF]
Earth Surface Dynamics, 2021 Wave-transported boulders represent important records of storm and tsunami impact over geological timescales. Their use for hazard assessment requires chronological information on their displacement that in many cases cannot be achieved by established ...

Radiocarbon and OSL dating on cores from the Chaoshan delta in the coastal South China Sea
Frontiers in Marine Science, 2022 Accurate chronology plays a crucial role in reconstructing delta evolution. Radiocarbon (14C) and optically stimulated luminescence (OSL) dating are widely used to establish a stratigraphic chronology of the late Quaternary sediments.

Agricultural terraces in the Mediterranean: medieval intensification revealed by OSL profiling and dating [PDF]
Antiquity, 2021 AbstractThe history of agricultural terraces remains poorly understood due to problems in dating their construction and use. This has hampered broader research on their significance, limiting knowledge of past agricultural practices and the long-term investment choices of rural communities.
