The Dating and Interpretation of a Field Wall in Öggestorp

Current Swedish Archaeology, 2004
The interpretation of the use and contextual meaning of fossil agrarian forms is connected with their age. In this article we discuss the dating and interpretation of a field wall in Öggestorp, situated on the northern rim of the southern Swedish ...

Dose dependency of aliquot sizes and age models from modern alluvial fan deposits of Helan Mountain, China

Frontiers in Earth Science, 2022
Alluvial fan deposits are identified as evidence of regional climatic variations and tectonic events; therefore, it is crucial to establish absolute time series by dating alluvial fan deposits.

The late Quaternary slip-rate of the Har-Us-Nuur fault (Mongolian Altai) from cosmogenic Be-10 and luminescence dating [PDF]

, 2009
The Altai range (western Mongolia) accommodates NNE–SSW shortening across the northern India–Eurasia collision zone by dextral slip on faults trending NNW–SSE, and anticlockwise, vertical-axis rotations of fault-bounded blocks.

Quantification of termite bioturbation in a savannah ecosystem: Application of OSL dating [PDF]

Quaternary Geochronology, 2015
Abstract Luminescence dating is one of the most promising technique available for studying bioturbation on pedological timescales. In this study, we use multi-grain and single-grain quartz OSL to quantify termite bioturbation processes ( Macrotermes natalensis ) in a savannah ecosystem in Ghana.

Dating the Aterian using techniques of luminescence dating and implications for mapping the dispersal of modern Homo sapiens

, 2022
The Aterian is a Middle Stone Age technocomplex that occurs throughout North Africa, typically identified by the presence of pedunculates. Due to widespread radiocarbon dating of contaminated samples, most Aterian sites are not well-dated.

Data set on sedimentology, palaeoecology and chronology of Middle to Late Pleistocene deposits on the Taimyr Peninsula, Arctic Russia

Data in Brief, 2019
This Data in Brief paper contains data (including images) from Quaternary sedimentary successions investigated along the Bol'shaya Balakhnya River and the Luktakh–Upper Taimyra–Logata river system on southern Taimyr Peninsula, NW Siberia (Russia). Marine

Studies on OSL of Quartz and Feldspar for Dating of Sediments.

RADIOISOTOPES, 2001
石英, 長石の光励起ルミネッセンス (OSL) 現象を年代測定に応用するための基礎実験を行った。4種類の石英と5種類の長石の標本試料および天然の堆積物試料を用いて, 測定温度, 励起光波長, プレヒート条件, アニールおよび光ブリーチの違いによるルミネッセンス強度の変化, また人為的なタイムゼロイングによるルミネッセンスの線量依存性の変化を実験的に調べた。さらに同一試料によって光ルミネッセンスを測定した後の熱ルミネッセンス測定を行った。これらの結果から, OSL法による年代測定条件を検討した。

Apparent OSL ages of modern deposits from Fåbergstølsdalen, Norway : implications for sampling glacial sediments

, 2013
This work was funded by NERC, grant number F008589/1The application of optically stimulated luminescence (OSL) dating within glacial settings can be limited where sediments have not had their OSL signal fully reset by sunlight exposure.

Optically stimulated luminescence and isothermal thermoluminescence dating of high sensitivity and well bleached quartz from Brazilian sediments: from Late Holocene to beyond the Quaternary?

Brazilian Journal of Geology
: The development of optically stimulated luminescence (OSL) dating of sediments has led to considerable advance in the geochronology of the Quaternary.

Investigation of OSL surface exposure dating to reconstruct post-LIA glacier fluctuations in the French Alps (Mer de Glace, Mont Blanc massif) [PDF]

, 2018
Providing quantitative constraints on late Pleistocene glacier fluctuations remains an important challenge for understanding glacier response to past and future climate changes.
