The Liverpool Luminescence Laboratory is a world-class research facility with the capabilities to perform cutting-edge luminescence dating techniques for determining the timing of sediment deposition or exposure. Please e-mail Dr Smedley rachel. Luminescence dating is a geochronological technique that can determine the timing of sediment deposition using quartz or feldspar. It relies upon the fundamental principle that mineral grains can store and release energy produced by radioactive decay. The radioactive decay of K, Rb, U and Th emits energy in the form of alpha and beta particles, and gamma rays, which exposes grains to an environmental dose-rate, in addition to the dose provided by the cosmic rays. This energy recharges the battery over time during burial. Defects or impurities in the crystal lattice of quartz or feldspar grains trap electrons, which are then excited and released when stimulated by light or heat.

Influence of pedon history and washing nature on luminescence dating of Holocene colluvium on the example of research on the Polish loess areas. Although colluvium is a valuable record of past human impact, there is a lack of a precise method of age determination.
The luminescence method could be used, but the basic difficulty is partial bleaching of quartz grains. In this study, colluviums from southern Poland were investigated using the OSL method. All examples for this study are colluviums deposited on Holocene fossil soils in dry valleys.

The development of the Risø TL/OSL reader started in with an automated TL education, DTU Nutech offers a training course in luminescence dating.
Over the last 60 years, luminescence dating has developed into a robust chronometer for applications in earth sciences and archaeology. The technique is particularly useful for dating materials ranging in age from a few decades to around ,—, years. In this chapter, following a brief outline of the historical development of the dating method, basic principles behind the technique are discussed. This is followed by a look at measurement equipment that is employed in determining age and its operation.
Luminescence properties of minerals used in dating are then examined after which procedures used in age calculation are looked at. Sample collection methods are also reviewed, as well as types of materials that can be dated. Continuing refinements in both methodology and equipment promise to yield luminescence chronologies with improved accuracy and extended dating range in the future and these are briefly discussed.
Luminescence – An Outlook on the Phenomena and their Applications. Luminescence dating refers to age-dating methods that employ the phenomenon of luminescence to determine the amount of time that has elapsed since the occurrence of a given event. In this chapter, the application of luminescence techniques in dating geological and archaeological events is examined. Generally, the term luminescence dating is a collective reference to numerical age-dating methods that include thermoluminescence TL and optically stimulated luminescence OSL dating techniques.
Other terms used to describe OSL include optical dating [ 1 ] and photon-stimulated luminescence dating or photoluminescence dating [ 2 ]. Luminescence dating methods are based on the ability of some dielectric and semiconducting materials to absorb and store energy from environmental ionizing radiation. In earth sciences and archaeological applications, the dielectric materials are usually minerals such as feldspar and quartz.
Highlands Receives Grant for Luminescence Dating Lab
Luminescence dating including thermoluminescence and optically stimulated luminescence is a type of dating methodology that measures the amount of light emitted from energy stored in certain rock types and derived soils to obtain an absolute date for a specific event that occurred in the past. The method is a direct dating technique , meaning that the amount of energy emitted is a direct result of the event being measured.
OSL dating can be used to date sediments from decades up to , years in exceptional circumstances although the technique is more.

Our research uses a variety of analytical methods from the earth sciences to address key questions in archaeological science in Australia and worldwide, and the deep history of Indigenous cultures. The Archaeological Science Theme, led by Professor Rachel Popelka-Filcoff , Kimberley Foundation Minderoo Chair in Archaeological Science, brings together dating techniques, geochemical, paleomagnetic, mineralogical and isotopic analyses, palynology and geomicrobiological methods to bear on important problems of the deep history of Indigenous cultures in Australia and elsewhere.
Our interdisciplinary work spans cultures and geography to understand key questions around the age, history, provenance, technology and composition of cultural heritage materials and sites and those who created them, and brings together scientists, humanities and social science scholars and communities. Research currently includes a large multi-disciplinary project to date the remarkable Aboriginal rock art in the Kimberley region of north-western Australia, in collaboration with archaeologists, traditional owners and other researchers in Australia and elsewhere.
The work is based on radiocarbon dating of mud wasp nests, uranium-series dating of surface mineral accretions, cosmogenic radionuclide dating of rock falls and optically stimulated luminescence dating of large mud-wasp nest complexes that are related to the previously established rock art sequence. The work also involves detailed studies of the geomorphologic evolution of rock shelters, the mineralogy and geochemistry of rock surface processes, and catchment-wide landscape evolution patterns.
New research is being undertaken to identify the origins and movements of Australian archaeological ochre through the development of a novel tool combining genomic and chemical analysis. This project hopes to answer significant questions about past human behaviour, in terms of trade, cultural interactions, territoriality and colonisation. This collaboration of analytical chemists, archaeologists and genomic scientists and collaboration with Indigenous communities works with advanced methods in compositional analysis, genomic sequencing and experimental archaeology.
Research is also being conducted on important prehistoric sites in Laos and Cambodia , and a variety of palaeoenvironmental studies. Current research in Cambodia is focussed on Iron Age societies and the emergence of socio-political complexity prior to the rise of the Angkorian state. Research in progress includes the isotopic analysis of ancient human skeletal material to investigate residential mobility and resource acquisition strategies, the creation of isotopic baseline maps and compositional analyses of material culture.
This interdisciplinary research includes isotopic analyses of skeletal material found buried around the megaliths, analysis and conservation of material culture, optically stimulated luminescence dating of sediments beneath the jars to gauge the period of emplacement, and remote sensing to record the sites and geo-reference the megaliths for spatial analysis and ongoing conservation measures.
Our researchers also use paleomagnetic and archaeomagnetic analysis for Australian Archaeological Science.
