Dating mortar by optically stimulated luminescence: A feasibility study [PDF]

open access: yesGeochronometria, 2011
Quartz is the datable component in mortar. Although its luminescence properties are very well studied, the problem of mortar dating arises from a low level of optical bleaching. In order to reduce the time consuming efforts for dating lime mortar in monuments by optically stimulated luminescence, we investigated the most suitable methods of dose and ...

Towards the optically stimulated luminescence dating of unheated flint

open access: yesQuaternary Geochronology
Flint tools are important archaeological finds, but unheated specimens remain challenging to date. The optical luminescence properties of the microcrystalline flint differ from sedimentary quartz grains, and optically stimulated luminescence (OSL) has, therefore, only occasionally been used to date heated flint specimens.

Mid- to Late-Quaternary evolution of the Wilderness Barrier dunes, South Africa [PDF]

open access: yes, 2011
Barrier dunes represent potentially long-term, but complex, archives of coastal evolution. The examples occupying the Wilderness embayment, on the southern Cape coast of South Africa, form a regionally unique system of three shore-parallel barriers ...

Timing of Sedimentary Evolution and Transgressions in the Bohai Sea During the Last ∼200 ka: Constraints from Luminescence Dating of a Core from the Yellow River Delta

open access: yesFrontiers in Earth Science, 2022
The southwestern coast of the Bohai Sea is a favorable area to study land-sea interactions and palaeoenvironmental changes. The Bohai Sea hosts vast volumes of sediment discharged from rivers of mainland China and has undergone large-scale sea-level ...

On the analysis of photon arrival time distributions obtained using the pulsed optically stimulated luminescence technique [PDF]

open access: yes, 2022
The objective of this work is to address the analysis of photon arrival time distributions (PATDs) obtained using the pulsed optically stimulated luminescence (POSL) technique in two particular situations: (a) when the interval between pulses is ...

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

open access: yesEiszeitalter 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 ...

Timing and dynamics of Late Wolstonian Substage ‘Moreton Stadial’ (MIS 6) glaciation in the English West Midlands, UK

open access: yesRoyal Society Open Science, 2022
Glaciation during the late Middle Pleistocene is widely recognized across continental northwest Europe, but its extent and palaeoenvironmental significance in the British Isles are disputed. Although glaciogenic sediments at Wolston, Warwickshire, in the

The problem of dating quartz 1 : Spectroscopic ionoluminescence of dose dependence [PDF]

open access: yes, 2010
This work is partially supported by NERC studentship F008589/1.A suite of quartz samples of different provenances, irradiation, thermal and depositional histories were analysed using spectroscopic ionoluminescence (IL) to investigate variations in ...

Luminescence characteristics of muddy sediments in the turbidity maximum zone of the Yangtze River mouth and implications for the depositional mechanisms

open access: yesFrontiers in Earth Science, 2022
Muddy sediments are the most prominent constituents of sedimentary successions in tide-dominated river deltas and have highly complex depositional mechanisms.

Last interglacial (MIS 5e) sea-level proxies in southeastern South America [PDF]

open access: yesEarth System Science Data, 2021
Coastal southeast South America is one of the classic locations where there are robust, spatially extensive records of past high sea level. Sea-level proxies interpreted as last interglacial (Marine Isotope Stage 5e, MIS 5e) exist along the length of the
