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.
4. Luminescence Dating of Archaeological Materials
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.

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.
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.
These slowly decay over time and the ionizing radiation they produce is absorbed by mineral grains in the sediments such as quartz and potassium feldspar. The radiation causes charge to remain within the grains in structurally unstable “electron traps”.
Scientific dating uses biological and physical methods for assessing the time when other forms of scientific dating such as archaeomagnetic and luminescence dating. Part of projects funded under the National Heritage Protection Plan.

Abstract Half a century after the publication of the first Thermoluminescence TL ages, the field of Luminescence Dating has reached a level of maturity. Both research and applications from all fields of archaeological science, from archaeological materials to anthropology and geoarchaeology, now routinely employ luminescence dating.
The advent of optically stimulated luminescence OSL techniques and the potential for exploring a spectrum from mono-minerallic single grains to polymineral multi-aliquots enhanced the applicability, accuracy and the precision of luminescence dating.

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

A device that measures exposure to ionizing radiation. The current and most recent of the three periods of the Cenozoic Era in the geologic time scale. It follows the Neogene Period and spans from approximately 2. The Quaternary Period is divided into two epochs: Luminescence dating is frequently used for age determination of Quaternary period materials such as archaeological artefacts, volcanic deposits and a variety of sediments from different environmental settings.
A common property of certain minerals such as quartz and feldspar is that when they are exposed to radioactivity, they are able to store within their crystal structure the energy delivered by the radiation.

Age determination by the luminescence dating method is based on measuring the luminescence of samples that contain quartz or similar minerals. Accurate determination of the luminescence signal is essential and closely related to the sample preparation. Many kinds of techniques are used for sample preparation in Optically Stimulated Luminescence and Thermoluminescence dating. In this study, different sample preparation techniques, including crushing by hand or mortar, sieving by hand or sieve shaker and chemical application were compared.
Different groups of samples were prepared and then the OSL and TL luminescence signals were examined.

Luminescence dating typically refers to a suite of radiometric geologic dating techniques whereby the time elapsed since the last exposure of some silicate minerals to light or heat can be measured.
When dosed minerals are then re-exposed to light or heat, they release the stored electrons, emitting a photon of light that is referred to as luminescence. The electron may become trapped at a defect site T1, T2 etc for some time Storage. When the crystal is stimulated by light or heat, the electrons in the traps are evicted into the conduction band Eviction. From there, they can recombine with holes at the luminescence centers L , resulting in the emission of a photon of light — the luminescence signal that is observed in the laboratory.

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. Active areas of research in which potential doctoral projects can be defined include the dating of: 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. In the case of pottery, the most recent heating is assumed to represent the manufacturing event.
Similarly, erosion, transport and deposition of sediments exposes the quartz to daylight, thereby resetting the stored energy in the quartz. Thus in luminescence dating, the event being dated is this initial resetting, either by heat or by exposure to light. Radioactive decay of ground uranium, thorium and cosmic radiation, provides a constant irradiation field.
Therefore, the minerals in the sediment or archaeological objects are irradiated at a constant rate, and hence acquire luminescence energy at a constant rate.
