It had long been thought that ancient man had abandoned the shores of Britain during the period , to 65, BCE, but new excavations in Kent England shed some doubt on this. A combined team from Southampton University and Oxford Archaeology, funded by the UK’s Highways Agency, have found worked flints whilst excavating a new motorway junction near Dartford.
The sediment in which they were found has been dated at , BCE, at a time when the severe cold dropped the sea levels and the Neanderthals walked on a land bridge from what is now Northern France, into Kent, folowing the game which was migrating northward. The system of dating used was OSL optically stimulated luminescence. This technique measures the amount of light emitted from a grain of sand or other crystalline material, to calculate when it was last exposed to sunlight. Dr Whittle, from Durham University, has doubts over how accurate OSL dating is, postulating that the technique is “in constant development”.
He also stated that “I suspect there is a possibility that OSL dating might not be giving us the true date”.

Sections sampled for optically stimulated luminescence (OSL) dating within the Screen Hills complex, near the southeast coast of Ireland. (A).
Optically stimulated luminescence OSL dating has been applied to determine the burial age of sediment horizons within a sequence containing Lower Palaeolithic artefacts on an upland site associated with a solution feature doline at West Cliffe, located on the North Downs in Kent, UK. A detailed examination of the uniformity of the distribution of radionuclide sources in the sampled volumes was also performed and this included the application of a spatially-resolved technique for beta dose rate measurement.
The OSL ages, obtained for the burial of brickearth positioned stratigraphically below and above a clay and flint clast layer containing the artefacts and debitage, place the deposition of the artefacts to between ca and 80 ka ago. If displacement occurred on other upland sites this finding has important implications for establishing the timing of hominin use of the upland areas which, beyond broad attribution to Lower or Middle Palaeolithic origin, is uncertain and similar doubts apply to the interpretation of the environments that prevailed.

EP41A Fluvial fan evolution during Late Quaternary climate changes: field and chronological constraints from the Indo—Gangetic basin. Abstract: The stratigraphic evolution of fluvial fans is to a large extent governed by channel avulsion. Spatial variations in alluvial architecture are influenced by avulsion magnitude and frequency. However due to the absence of long—term chronostratigraphic records of fan stratigraphy, it has proved difficult to test patterns of fan evolution against records of climate variability.
In order to understand the processes of channel avulsion during fan evolution, it is important to determine the spatio—temporal pattern of fluvial channel aggradation, incision, and migration. In this study, we reconstruct the shallow sub—surface alluvial stratigraphy of fluvial fan systems formed by the major Himalayan rivers, the Sutlej and Yamuna, in the northwestern Indo—Gangetic basin.

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.

Luminescence Dating of Medieval and Early Modern Brickwork
Document reference: Search. Comprises archaeological assessments of brick buildings in Essex dating from the 11th to the 16th centuries, with revisions based on luminescence dating. Suggests evidence for a small scale late Saxon brick industry, and for widespread re-use of bricks. Includes discussion of the production and use of brick in medieval England and specifically in Essex, methods of dating, and theory and practice of optically stimulated luminescence OSL.

Access to water resources was vital for the survival of ancient peoples inhabiting arid landscapes. In such regions, surface water quickly becomes unavailable through evaporation or infiltration into the subsurface. To gain access to the subterranean water supply required new and innovative techniques. One example of this innovation was the development of the qanat: an underground channel. Through the construction of qanats, the groundwater supply could be unlocked and utilised for irrigation and consumption.
Along the path to its final destination, a number of vertical shafts are dug into the horizontal tunnel to: 1 allow for better oxygen supply to the workers; 2 easily remove the excavated material; and 3 provide ease of access during routine maintenance of the tunnel.

Although the type site for the LGM glaciation of Britain is on the Holderness coast at Dimlington, very poor chronological control is otherwise available for the pattern of advance and recession by the North Sea Lobe NSL , the major outlet of the British-Irish Ice Sheet whose potentially dynamic and pulsed behaviour has been the subject of considerable speculation due to limited chronological control on marginal oscillations. Not only the dynamics but also the configuration of this large outlet of the BIIS are poorly understood, and existing palaeoglaciological reconstructions depict a glaciologically improbable configuration, with east coast-parallel flow that requires a buttressing ice mass in the North Sea despite the lack of unequivocal evidence for such a shelf-based ice mass1,2.
An alternative scenario is that the forebulge of the Scandinavian Ice Sheet could have confined the flow of the NSL3, although this remains untested. Our understanding is hampered by a lack of knowledge of offshore sediment-landform assemblages and a dearth of dates on their emplacement. Ice flow directional indicators reveal a clear pattern of onshore, radial flow by the western margin of the NSL, which deposited prominent till sheets, moraines and ice-dammed lake sediments, but offshore limits are related only tentatively to the extent of the weakly chronologically constrained Bolders Bank Formation4, and marginal recession patterns and rates are unknown.
Because of the late marine inundation of the North Sea during immediate deglaciation, there is no glacimarine or glacioisostatic record of ice sheet recession along the eastern England coast, but the region was subject to glacial loading nonetheless and therefore would have been extensively flooded by proglacial lake waters, as evidenced by the extensive glacilacustrine sediments in the onshore stratigraphies.

With few exceptions in which dating is implied by indirect association with adjacent settlements or incorporation of diagnostic artefacts in upcast sediment, individual qanats have proven very difficult to date. This absence of a chronological framework hampers both our understanding of technology transfer, as well as the study of local settlement and landscape evolution and the temporal correlation of land use with climatic and palaeoenvironmental data.
However, surface shaft mounds potentially contain a sequence of upcast deposits collected periodically from the tunnel, starting with initial construction and persisting until the last maintenance episode, less any material lost by surface erosion.
