Investigation into main luminescence properties of various natural salt samples using TL and OSL tecniques

Фізика і хімія твердого тіла
In this study, the natural salt minerals of Turkey were investigated using Thermoluminescence (TL) and optically stimulated luminescence (OSL). For this purpose, luminescence dosimetric properties such as glow curve shape, fading, dose-response ratio ...

Variation of luminescence sensitivity of quartz grains from loess in eastern Tibetan Plateau and its provenance significance

Frontiers in Earth Science, 2022
The loess deposits widely distributed in the eastern Tibetan Plateau (ETP) are important archives for reconstructing the paleoenvironmental changes and dust transportation history of the Tibetan Plateau.

Single‐grain K‐feldspar luminescence dating on primary and re‐deposited aeolian sediments in Mongolia

Boreas, EarlyView.
Owing to its location in the semi‐arid region of northern Central Asia, Mongolia is highly sensitive to climate change and therefore provides an excellent setting for palaeoenvironmental research. Proxy data from different sediment types are crucial for interpreting past climate changes and landscape evolution, while burial ages provide chronological ...

Application of Multi‐Method Dating for Understanding the Gravettian North of Moravia, Central Europe

Archaeometry, Volume 68, Issue 5, Page 1050-1061, October 2026.
ABSTRACT This article presents the results of integrating three methods to assess the age of the Upper Palaeolithic site of Pietraszyn 11 (SW Poland), close to the Moravian Gate. Sediment chronology determined using optically stimulated luminescence produced promising, yet ambiguous results (51.0 ± 3.7 to 20.3 ± 0.7 ka).

Luminescence analysis of a postglacial landscape in northeastern Norway and northern Finland

Boreas
Portable optically stimulated luminescence (pOSL) analysis allows rapid relative dating of sediments that potentially can be calibrated against known OSL ages to provide an age estimate for landforms across a large area.

The Parguera Fault System: Possible Quaternary Reactivation of Bedrock Faults in Southwest Puerto Rico

Tectonics, Volume 45, Issue 9, September 2026.
Abstract We present evidence of a previously unrecognized east‐west‐trending normal fault, named the Parguera Fault, in southwest Puerto Rico. The fault is located at the northwestern edge of seismicity from the southwest Puerto Rico seismic sequence that began in 2019, near the coastal town of La Parguera.

Evaluating post-glacial bedrock erosion and surface exposure duration by coupling in situ optically stimulated luminescence and ¹⁰Be dating [PDF]

Earth Surface Dynamics, 2019
Assessing the impact of Quaternary glaciation at the Earth's surface implies an understanding of the long-term evolution of alpine landscapes. In particular, it requires simultaneous quantification of the impact of climate variability on past glacier ...

Systematic review of physical and dosimetric criteria for managing CIEDs in radiotherapy: A medical physicist's perspective

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Aim Current radiotherapy (RT) guidelines for Cardiac Implantable Electronic Devices (CIEDs) are largely based on clinical management strategies and retrospective reports. This systematic review adopts a medical physics perspective to provide a critical, quantitative analysis of the technical evidence required for developing robust safety ...

Surface ages of alluvial fans in the southern Central Andes recorded by ground‐ and space‐based hyperspectral reflectance

Earth Surface Processes and Landforms, Volume 51, Issue 8, August 2026.
Secondary weathering of alluvial‐fan surfaces records the relative, and even absolute, ages of deposited sediments up to 300 ka. Hyperspectral imagery quantifies evolving mineral‐weathering pathways to unlock high‐resolution mapping and dating of these sedimentary landscapes.
