Optically stimulated luminescence dating of pottery from Turkey

, 2000
In this study, the potential of optically stimulated luminescence (OSL) dating for archaeological potteries was investigated. Firstly, recently purchased OSL and alpha counter systems were calibrated.

Comparative 14C and OSL dating of loess-paleosol sequences to evaluate post-depositional contamination of n-alkane biomarkers [PDF]

, 2017
There is an ongoing controversial discussion as to whether n-alkane lipid biomarkers—and organic matter of loess in general—reflect a synsedimentary paleoenvironmental/climate signal or whether they are significantly affected by postdepositional ...

First Record of Tasmanian Devils in the Pilbara: Late Quaternary Subfossils From Juukan Gorge, Puutu Kunti Kurrama Country, and Insights Into Human—Faunal Relationships and Extinction

Archaeology in Oceania, EarlyView.
ABSTRACT This study presents the first unequivocal evidence for the presence of Tasmanian devils (Sarcophilus harrisii) in the Pilbara region of northwestern Australia, based on material recovered from archaeological excavations at Juukan Gorge on Puutu Kunti Kurrama and Pinikura country.

Repeated Pleistocene Permafrost Episodes in the Western Pannonian Basin

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Concerning the study of past periglacial processes, the Pannonian Basin is a key area as it contains the southernmost frost polygons found in Central Europe. The presence or absence of permafrost is still, however, a matter of debate, and data on the timing of frost action are also scarce.

4th and 5th seasons of the Nubian Expedition of the Anuchin Research Institute and Museum of Anthropology, Lomonosov Moscow State University at the Sites of Deraheib and Onib (the Republic of Sudan). Part I. Survey of the Stone Age Sites at the Onib Depression

Вестник Московского Университета. Серия XXIII: Антропология, 2023
Introduction. The Nubian expedition of the Lomonosov MSU carried out survey in the Onib Depression in December 2022. The survey revealed several surface scatters and two stone age sites Onib-1 and Onib-Outcrop. Materials and methods.

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。

A Bayesian analysis of luminescence dating [PDF]

, 2008
Luminescence dating is a widespread dating method used in the fields of archaeology and Quaternary science. As an experimental method it is subject to various uncertainties in the determination of parameters that are used to evaluate age.

A reappraisal of the Middle to Later Stone Age prehistory of Morocco Réévaluer la préhistoire du Maroc, du Middle Stone Age au Later Stone Age

Journal of the Royal Anthropological Institute, EarlyView.
Over the last 25 years, perceptions of the early prehistory of Northwest Africa have undergone radical changes due to new fieldwork projects and a corresponding growth in scientific interest in the region. Much of this work has been focused in Morocco, known for its extremely rich fossil and archaeological records in caves and rock shelters.

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.

Safelight for OSL dating laboratories: a follow-up study

Ancient TL, 2021
We introduce a new lamp for use in optically stimulated luminescence (OSL) dating laboratories. The lamp is based on an LED with the peak emission wavelength at 594 nm that was previously characterised as safe for both samples and operators by Sohbati et al. (2017). We demonstrate that 48 h exposure to this lamp, delivering a power density of 0.2 µW.cm-
