Dating of late Pleistocene and Holocene fluvial sediments Using OSL, Uranium series and 14C methods in the Saqqez River [PDF]

Sustainable Earth Trends, 2022
Fluvial sediment dating surveys are one of the quaternary researches which can help to explicit many environmental issues. In the present study, samples taken to direct age determination belong to a depositional profile located in one of the tributaries ...

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.

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.

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.

Towards an improvement of optically stimulated luminescence (OSL) age uncertainties: modelling OSL ages with systematic errors, stratigraphic constraints and radiocarbon ages using the R package BayLum [PDF]

Geochronology, 2021
Statistical analysis has become increasingly important in optically stimulated luminescence (OSL) dating since it has become possible to measure signals at the single-grain scale.

A Review of Single-grain Optically Stimulated Luminescence Technology and Its Application in Geological Archaeology

Yankuang ceshi, 2020
BACKGROUND In recent years, a series of important progressions has been made in the study of single-grain technology in optical stimulated luminescence (OSL) dating, which greatly improves the accuracy of dating and provides more space for geological and

Potential and limits of OSL, TT-OSL, IRSL and pIRIR₂₉₀ dating methods applied on a Middle Pleistocene sediment record of Lake El'gygytgyn, Russia [PDF]

Climate of the Past, 2013
This study tests the paleomagnetic and proxy-data based Mid- to Upper Pleistocene sediment deposition history of Lake El'gygytgyn by applying different approaches of luminescence dating techniques on sediment cores taken from the centre of the 175 m deep

Timing of Medieval Fluvial Aggradation at Bremgarten in the Southern Upper Rhine Graben – a Test for Luminescence Dating [PDF]

Eiszeitalter und Gegenwart, 2009
The Holocene flood plain of the River Rhine is a complex dynamic sedimentary system. A series of geochronological results for the Bremgarten section including optically stimulated luminescence (OSL) and radiocarbon dating was determined to improve the ...
