Kaja Fenn. You might have heard about radiocarbon dating, but do you know about OSL dating? OSL stands for O ptically S timulated L uminescence, and is another method of determining when processes and events occurred in the past. It has some distinct advantages over radiocarbon dating, which I will discuss. Scientists look at biological indicators, such as pollen, and geochemical signatures like oxygen isotopes , through to physical properties of sediment, such as the shape and size. From these scientists are able to reconstruct for example past temperatures, climate, precipitation, vegetation, windiness, or animal assemblages. However, without a chronology, we would still have lots of unanswered questions. For example, did events occur on a global scale or just regionally.

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.

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.

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. Once completely charged, the battery-like grain is considered as being saturated. This upper age limit of OSL dating depends on the ability of the grain to store the energy and on the rate at which the grain is charged i.
Luminescence dating refers to a group of methods of determining how long ago mineral grains were last exposed to sunlight or sufficient heating. It is useful to geologists and archaeologists who want to know when such an event occurred. It uses various methods to stimulate and measure luminescence. All sediments and soils contain trace amounts of radioactive isotopes of elements such as potassium , uranium , thorium , and rubidium.

Contact Professor Ian Bailiff email at ian. After reading physics at Sussex University Ian Bailiff joined the Research Laboratory for Archaeology and the History of Art at Oxford as a postgraduate student and subsequently submitted a research MSc on the development of new luminescence dating techniques. Following a further year working on an instrument development project he came to Durham in as a research assistant on a pottery dating project; following a series of appointments as a Research Fellow he was awarded an SERC Advanced Fellowship, and in was appointed a Lecturer.
He was Head of Department between and He has developed a luminescence dating laboratory with the capability to support both dating and methodological investigation, and his research has included the study of the luminescence properties of minerals, their application to dating and also to radiation dosimetry. Currently the primary materials of interest are sediments from prehistoric sites and ceramic materials from medieval buildings and structures. Recent work on the dating of brick from medieval buildings of known age has shown that luminescence is capable of providing reliable and accurate results.
The work on medieval buildings, combined with an interest in instrumentation, has included collaborative work on the application of infrared thermography to the structural analysis of medieval buildings with Prof. Danny Donoghue in the Geography Department. Ian is Joint Editor-in-Chief of the journal Radiation Measurements which, within its broad remit of radiation-related research, includes luminescence and ESR dating.
Optically stimulated luminescence dating at Rose Cottage Cave. A single-grain analysis demonstrates that the testing procedure for feldspar fails to reject single aliquots containing feldspar and the overestimate of age is attributed to this. Seven additional luminescence dates for the Middle Stone Age layers combined with the 14 C chronology establish the terminal Middle Stone Age deposits at 27 years ago, while stone tool assemblages that are transitional between the Middle Stone Age and the Late Stone Age are dated to between 27 years and 20 years ago.
Although there are inconsistencies in the Middle Stone Age dates, the results suggest that the Howiesons Poort at Rose Cottage Cave dates to between 70 years and 60 years ago. Much of the rich archaeological heritage in southern Africa is older than 50 years, which is the limit of the ubiquitous 14 C dating technique.

COARS have been selected to help develop guidelines on the use of different dating techniques for Pleistocene sites and deposits, and produce a document for publication and web dissemination in the Historic England English Heritage guidelines series. Dating methods currently available for the Pleistocene are applicably to different time frames within this period, vary considerably in precision and accuracy, and in addition are also subject to rapid development and improvement.
The guidelines will cover a range of techniques useful for dating deposits, sites and artefacts of Palaeolithic or Pleistocene age, to cover the period from c. The guidelines will provide practical advice on the application of different dating methods available for Pleistocene archaeological projects in England. Many archaeological projects will be undertaken as a requirement of the planning process. For these projects, the National Planning Policy Framework Department for Communities and Local Government sets out planning policies on the conservation of the historic environment in England.
This document clarifies, for all those involved with the planning process, how dating methods can be used to assess the significance of Palaeolithic heritage assets and mitigate impacts of development on them. It is a material consideration for local authorities when preparing development plans and determining planning applications. These guidelines are intended to provide guidance for non-Pleistocene specialists tasked with managing or curating the Palaeolithic and in particular:.

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. The WSI provides for investigations of the archaeological features within the gravel extraction area, using a combination of excavation and recording methodologies.
It also provides for collection of samples for dating the monument features, and in particular for assessment of the suitability for optically stimulated luminescence OSL dating. This summary report describes the fieldwork undertaken by the Scottish Universities Environmental Research Centre SUERC in September and October to retrieve sediment samples from key features to be used in assessing the suitability of the material for OSL dating, and to provide material for OSL dating analyses during post-excavation stages.
