book review: Luminescence dating: guidelines on using luminescence dating in archaeology: G.A.T. Duller, Swindon: English Heritage,

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.

Site visits took place on the 8th – 9th September and the 6th October , over which period six sections were sampled for luminescence profiling and additional samples were collected for full dating analysis. Initial OSL screening was performed on site using portable OSL equipment, and in-situ gamma spectrometry was used to record environmental dose rates in the positions of the dating tube samples. During the field trip gamma dose rate measurements were made at the positions of all 11 full dating samples.

Profile 1 was taken through the main ditch section ; 14 profiling samples covering the primary substrate, the lower coarse fills, and two finer fills representing natural sedimentation after the primary use and infilling of the ditches. A set of five dating samples was collected through this section, which represent the sequence of early and later fills, with the aim of dating the infilling chronology.

In a section section between the southern and northern ditches a preserved soil was exposed which lies on material presumed to represent the gravel substrate, and is in turn covered by material attributed to part of the bank associated with the southern cursus ditch. A series of eight profiling samples was collected through these deposits to assess the suitability of the material for OSL dating, and five dating tubes were collected with associated gamma spectrometry data to represent the depositional sequence.

The significance of these samples is that the lower units will define the environmental history of the substrate and early soil formations prior to construction of the cursus monument.

Luminescence Dating of Pottery and Bricks

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.

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:. Services Expertise Experience News Contact us.

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.

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 area was reclaimed by installing extended runoff terrace systems and hydraulic structures. The agricultural terrace systems have so far been dated based on surface pottery, and the chronology of the systems is under debate.

In this study, optically stimulated luminescence OSL and radiocarbon dating techniques were successfully applied to date these terrace systems. Samples were taken from the fills of agricultural terraces and underneath their walls to determine the chronology of the construction, use and abandonment.

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. This journal is the primary source of information for physics related aspects of these two methods, and since , the journal has included Special Issues devoted to the papers of the International Conference on Luminescence and ESR Dating. The experimental techniques developed for dating can also be applied to the measurement of radiation dose in the environment using ceramic materials, a field in which the laboratory has developed world-leading expertise.

Over the last 20 years the Clarendon Park Project CPP has investigated and sought to conserve the royal palace, park and hunting lodge of England’s Norman and Plantagenet kings at Clarendon, Wiltshire. CPP has broken new ground in both the approach taken and the results obtained, namely in:. Clarendon Park is best known for its royal palace, a rare example of a royal residence outside London in the period The estate was sold by the Crown in , and subsequently passed through the hands of several private owners including the Earls of Clarendon between and , but has remained a coherent whole.

The present Clarendon Estate, with the palace ruins at its centre, is thus uniquely coterminous with the medieval royal park — the largest in England at ha — and therefore of considerable significance Richardson , James and Gerrard Despite its importance the palace and park have until recently been poorly maintained.

Protons which are positively charged. Neutrons which do not have a charge. The protons and the neutrons make up the centre of the atom called the nucleus and the electrons are constantly spinning above the nucleus in a small cloud. The number of protons in an atom of an element always remains constant but the number of neutron and electrons can change.

The number of neutrons in an atom can vary within small limits. For example, there are three kinds of carbon atom 12C, 13C and 14C.

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.
