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.
I am interested in dryland desert environments, and their interaction with climate. I investigate these climatic changes by studying the landscape dryland geomorphology , sediments sands and carbonates , and ground water chemistry hydrogeology and through applying luminescence dating and U-Th dating as geochronological methods. At the University of Manchester I convene a third year option about Dryland Environments, second year options in Quaternary Science and in Geomorphology and contribute to Physical Geography teaching within the first year programme Dynamic Earth module and Key Ideas module and within cross-disciplinary courses De-colonising Geographies.

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.

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.

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. They all have the same number of protons, but the number of neutrons varies. The fact that they have varying numbers of neutrons makes no difference whatsoever to the chemical reactions of the carbon.

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.
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.
