NCL – Netherlands Centre for Luminescence dating
Loess-paleosol sequences LPS are the most extensively available archives for the reconstruction of paleoenvironmental conditions in Central Europe. A huge amount of sections were published during the past centuries providing information concerning stratigraphy, geochemical, biological or sedimentological proxy data. Luminescence dating was applied to develop a chronological framework which allows for correlations to other archives and large-scale proxy data such oxygen isotopic stages or Greenland ice core data.

PhD award in Luminescence Dating for International Students Denmark 2020
Directed by Professor Mark D. Bateman, the Sheffield Luminescence Dating Facility was established in In recent years samples from all around the world have been dated, including archaeological sediments from the USA and South Africa, relict cold-climate desert sands from Arctic Canada, dune sands from Zambia, Zimbabwe, The Netherlands and UK and lake sediments from Mexico.
The Luminescence Dating and Dosimetry Laboratory is developing new techniques for E. Sauer at the University of Edinburgh, a PhD project has started to.
Luminescence dating is a technique used to date Quaternary sediments and for determining when ancient materials such as pottery, ceramics, bricks or tiles were last heated. The technique can be applied to material from about to several hundred thousand years old. It is primarily a research facility for the School and for collaborators in New Zealand. One room serves as preparation laboratory, where all incoming samples are unpacked and chemically treated to purify the sample and extract the desired minerals in the right grain size.
Please contact Ningsheng Wang MSc. We use optically stimulated luminescence OSL to date aeolian, fluvial, lacustrine and shallow water marine sediments, as well as most quartz or feldspar-bearing objects, which have seen sunlight or intense heat during deposition. These sediments can be used to study ancient earthquakes, tsunamis, flooding and volcanic eruptions, as well as climate change, glaciation and tectonic uplift. We are also involved in research projects requiring gammaspectrometry.
Applications involve measurement of artificial radionuclides in sediments such as Cs from atomic bomb tests or Am from the Chernobyl accident or measurement of sedimentation rates using naturally occurring Pb. Our equipment has a very high efficiency and ultra-low background so can be used to measure tiny amounts of radionuclides. We therefore welcome projects where low-level radioactivity is expected such as sediments from New Zealand and the Pacific Islands.
This price includes all irradiation and luminescence measurements required to obtain the equivalent dose, and high resolution laboratory gamma-spectrometry for dose rate determination. Please ask us for a quote for your sample analysis. Turnaround time is dependent on the workload of the lab, so please enquire about the status when submitting samples.
PhD candidate coastal sediment tracing using luminescence dating
Luminescence dating is a geochronological technique important for reconstructing past environments on Earth over the last million years see Smedley, for details. Routine luminescence dating has long been performed on sedimentary grains e. This provides a new, exciting opportunity to apply luminescence dating to mass movement processes e.
However, first we need to better understand the major uncertainty caused by the variability in the internal geochemistry of feldspar grains used for luminescence dating, especially for individual grains Smedley et al.
PhD candidate coastal sediment tracing using luminescence dating Published onFebruary 17, Location Wageningen We are looking for.
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. New approaches are being applied to the dating of post-Roman irrigation systems in Spain to establish when they were created and used. Also, as part of a major investigation supported by the European Research Centre and led by Prof.

PhD award in Luminescence Dating for International Students, Denmark
Location Wageningen. Do you want to explore how novel luminescence dating methods can be used to unravel how sediments move in a coastal system? And would you like to work as a PhD candidate in a multidisciplinary team? We are looking for a talented PhD candidate in the field of advanced methods for investigating earth surface dynamics.
This trapped signal is light sensitive and builds up over time during a period of no light exposure during deposition or burial but when exposed to light natural sunlight or artificial light in a laboratory the signal is released from the traps in the form of light — called luminescence. In this facility we aim to sample these minerals found in all sediments without exposing them to light so that we can stimulate the trapped signal within controlled laboratory conditions with heat thermoluminescence — TL or light optically stimulated-luminescence — OSL.
As most sedimentary processes or events are based on the deposition of sediment these depositional ages are critical to geomorphological research. In addition, the age of sediment deposition is also crucial for the evidence found within the sediment such as pollen, fossils and artefacts and therefore the technique is relevant for paleoclimatology, archaeological and paleontological research.
Therefore the facility supports existing research programs investigating climate change, natural hazards, coastal and river management, and human-environment interactions. The facility houses state-of-the-art luminescence preparation and measuring equipment within two specially designed subdued red-light laboratories. The facility, run by Dr Kira Westaway, contains a fully equip wet room preparation area with a core and tube opening station, HF fume hoods, wet and dry sieving and mineral separation stations, and a ball mill.
The facility was only opened in but already many samples have been processed that have contributed to HDR research in the Macquarie Marshes, research into the arrival of modern humans in northern Laos published in PNAS and methodological advancement into exploring the use of a dual signal approach published in Radiation Measurements. It is not a commercial facility but currently supports 7 Macquarie staff, 7 HDR students, HDR research and undergraduate teaching and 5 external collaborations.

PhD scholarship in Luminescence Dating Apply for the job at DTU Nutech by completing the following form. DTU Nutech, The Radiation.
Job listing. 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. Job description 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. The fundamental challenges in OSL dating are that such target materials may have a residual age at the time of deposition and that they may subsequently migrate within the burial matrix. To address these challenges, we will test the methodological hypotheses that i luminescence dating using multi-grain samples is significantly inaccurate compared to independent age control, and ii only single-grain dating provides accurate dates for Kostenki and related sites.
The successful applicant will work on all aspects of testing these hypotheses. Qualifications Master’s or equivalent degree in physics, chemistry, geoscience, archaeological science or similar.
