Applicants should apply before August 18, DTU Nutech, The Radiation Physics Division, is seeking candidates for a PhD position to investigate the chronology of the migration of early and modern humans using luminescence dating. These studies will be concentrated on the eastern European and western Asian plains, particularly around the famous Kostenki group of sites, and will be in collaboration with colleagues from the Russian and Siberian branches of the Russian Academy of Sciences. The Radiation Physics Division carries out research, innovation and research-based consultancy in the fields of dosimetry, luminescence physics, and neutronics, with applications within e. The division presently consists of approx. The aim of the PhD project is to investigate the hypothesis that Anatomically Modern Humans arrived on the central east European plain well before the presently accepted 42 ka. OSL dating of sand sized grains of quartz and feldspar is today one of the most important chronological tools in Late Quaternary geology and human evolution studies.
Luminescence dating potential
The Luminescence Dating and Dosimetry Laboratory is developing new techniques for application to the dating of artefacts and deposits from sites that range widely in terms of chronological period, geographic location and material type. Recent work as focused on optically stimulated luminescence OSL techniques, in particular a novel experimental approach to the measurement of single grain OSL. A study produced, for the first time, absolute dates for a range of brick stupas located within the hinterland of Anuradhapura , contributing to the further development of a brick monument chronology for the region.
Ongoing work is examining whether unfired clay bricks from various sites can be dated accurately. OSL techniques are being applied to date sediment sequences in stratigraphic contexts associated with irrigation systems. In the absence of suitable organic samples for C dating, these systems are very difficult to date.

Sommerville, Anne Amanda Luminescence dating of wind blown sands from archaeological sites in northern Scotland. PhD thesis, University of Glasgow. The sheltered bays of the Orkney Islands are backed by extensive dune systems that commonly contain archaeological sites, many of which now protrude from cliffed sections due to coastal erosion. In an area where other dating techniques are often precluded due to a lack of organic dating material, this research establishes that optically stimulated luminescence OSL dating can provide a viable and robust alternative by dating wind blown sands within the sites to constrain the archaeological age.
Since this is the case, the OSL chronology can also be applied to natural sites where no archaeological chronology exists and so be used in palaeoenvironmental reconstruction. The phases of sand movement identified using OSL in the Orkney Islands are also identified at other sites in Scotland and north-east Europe and support the chronologies derived from other environmental indicators such as tree rings and peat bogs. It is suggested that at least two events may be related to the deterioration in climate subsequent to the eruption of Hekla 4 in the late Neolithic and Hekla 3 in the late Bronze Age.
However, OSL dating requires that the latent luminescence signal within quartz and feldspar is rapidly reduced to near zero by exposure to light, yet the rate and extent of bleaching depends on the length of time that the grains are exposed and the light intensity at the time of exposure.
The dissertation presents improvements made to luminescent dating in tectonic areas, with examples of the application of luminescence to tectonic questions north of Death Valley, CA. The study of tectonics is incomplete without an understanding of fault processes through time. This can be difficult in areas with limited Quaternary age control. The technique of luminescence dating can provide absolute ages, but tectonic areas tend to exhume fresh material that can have poor luminescent properties.

Mass movement processes landslides, rockfalls are common in glacial and post-glacial landscapes, with timing related to rebound induced seismicity, rock-mass damage. More recently, permafrost degradation has been linked to increased rates of mass movements as thermal thresholds are crossed. With anthropogenic climate change in glacial and permafrost regions, it is important to understand how sensitive the frequency of mass movement processes in these environments are to warming temperatures. This project aims to apply new luminescence techniques to resolve the timing of large rock avalanches and more recent permafrost degradation induced debris flows of superficial sediments in the U.

This Phd project is an awarded grant from the faculty of Archaeology-‐ Yarmouk new techniques in luminescence dating to archaeological problems.
This centre, which was established in , integrates the activities of several colleagues here and abroad who work on geochronology, climate change, environmental change and human impacts, covering a range of different timescales — from the mid-Pleistocene to late Holocene. We carry out environmental reconstruction using a variety of techniques including luminescence dating, tephrochronology, pollen analysis, diatom analysis, dendrochronology and elemental analysis.
Our research into past environmental change can provide the scientific base to inform effective environmental policy and management. For example, recent research contracts have been from Countryside Council for Wales and from Natural England, concerned with assessing recent human impact on blanket bogs and on moorland. Another strand of research concerns recent changes in species distributions and phenology, particularly birds on population and individual-level responses to climate change , but also other taxa including plants.
We also work with a number of Archaeological Trusts and Archaeological consultancies. Anne Goodenough is an ecologist specialising in quantifying linkages between species and their biotic and abiotic environments, as well as how these change in response to external stimuli.
