Abstract Optically stimulated luminescence OSL dating is a versatile technique that utilises the two most ubiquitous minerals on Earth quartz or K-feldspar for constraining the timing of sediment deposition. It has provided accurate ages in agreement with independent age control in many fluvial settings, but is often characterised by partial bleaching of individual grains. Partial bleaching can occur where sunlight exposure is limited and so only a portion of the grains in the sample was exposed to sunlight prior to burial, especially in sediment-laden, turbulent or deep water columns. OSL analysis on multiple grains can provide accurate ages for partially bleached sediments where the OSL signal intensity is dominated by a single brighter grain, but will overestimate the age where the OSL signal intensity is equally as bright often typical of K-feldspar or as dim sometimes typical of quartz. In such settings, it is important to identify partial bleaching and the minimum dose population, preferably by analysing single grains, and applying the appropriate statistical age model to the dose population obtained for each sample. To determine accurate OSL ages using these age models, it is important to quantify the amount of scatter or overdispersion in the well-bleached part of the partially bleached dose distribution, which can vary between sediment samples depending upon the bedrock sources and transport histories of grains.

Kinnaird, T. Technical Report. This study supports an investigation into the construction, occupation and utilisation history of the Scorton Cursus site, undergoing archaeological investigations by Northern Archaeological Associates Ltd NAA in advance of gravel extraction at the Scorton Quarry, Scorton, North Yorkshire.

Scientific Research An Academic Publisher. Luminescence Characteristics of Feldspar from Nigeria. The luminescence characteristics of feldspar from Nigeria were investigated. The TL signal is reduced by IR stimulation, and the longer the stimulation the more pronounced the effect. The dose response curves for both the TL and the IRSL showed a linear relationship for the doses considered in the study.

Dating terraces, the most prominent feature of the agricultural landscape in many parts of the world, is a problem for archaeologists. This study presents an interdisciplinary approach that combines archaeological survey and excavations with direct sediment dating of terrace fill using Optically Stimulated Luminescence OSL. The study focuses on Ramat Rahel, a multi-period site located in the southern outskirts of modern Jerusalem, Israel, where, on a defined terraced slope chosen for a small-scale landscape archaeology project, three main phases of terrace construction and use were identified.
The results enable a comprehensive reconstruction of the changing local landscape through time and demonstrate the validity of OSL, when combined with archaeological investigations, as a reliable method for terrace dating.

The last 2. To be able to fully understand and interpret past climate variations the development of accurate and precise chronological techniques is crucial. Optically stimulated luminescence OSL dating is a strong geochronological tool that can be used to date across a wide time range, from the modern days to a few hundred thousand years ago. It has been used to date sediments in nearly all parts of the world. The event that is being dated is the last time the sediment has been exposed to daylight, which means that the luminescence age is directly related to the time of sediment deposition.
OSL dating is based on the ability of minerals to store energy Preusser et al. They work like small batteries, which get charged when the sediment is buried Fig. This is due to radiation from naturally occurring radioactive material uranium, thorium and potassium in the surrounding sediment, and from cosmic rays for samples closer to the surface.
Like a battery, the quartz and feldspar grains have a finite capacity for storing energy.

At the Netherlands Centre for Luminescence dating we develop new and improved luminescence dating methods, and we apply luminescence dating in collaboration with NCL partners and external users. We develop new and improved luminescence dating methods, and we apply luminescence dating in collaboration with NCL partners and external users. The Netherlands Centre for Luminescence dating is a collaboration of six universities and research centres in The Netherlands.
Luminescence dating determines the last exposure to light or heat of natural minerals, mainly quartz and feldspar. Thereby the method can be used to determine the time of deposition and burial of sediments, or the time of baking of ceramic artefacts pottery, brick. The method has a wide age range, covering the period from a few years to half a million years. Luminescence dating is ideally suited for aeolian and coastal deposits, but is increasingly and successfully used for a wide range of other depositional environments e.
