Luminescence Dating in Archaeology

Luminescence Measurements demonstrated by Ed Rhodes

This paper aims to provide an overview concerning the optically stimulated luminescence OSL dating method and its applications for geomorphological research in France. An outline of the general physical principles of luminescence dating is given. A case study of fluvial sands from the lower terrace of the Moselle valley is then presented to describe the range of field and laboratory procedures required for successful luminescence dating. The paper also reviews the place of OSL dating in geomorphological research in France and assesses its potential for further research, by focusing on the diversity of sedimentary environments and topics to which it can be usefully applied. Hence it underlines the increasing importance of the method to geomorphological research, especially by contributing to the development of quantitative geomorphology.

A review of current research on TL dating of loess. Share Flipboard Email. Kris Hirst. Kris Hirst is an archaeologist with 30 years of field experience. Updated August 24, Pottery : The most recent heating measured in pottery sherds is assumed to represent the manufacturing event; the signal arises from quartz or feldspar in the clay or other tempering additives.

Although pottery vessels can be exposed to heat during cooking, cooking is never at sufficient levels to reset the luminescence clock.

Luminescence can also be used to determine the original firing temperature. Lithics : Raw material such as flints and cherts have been dated by TL; fire-cracked rock from hearths can also be dated by TL as long as they were fired to sufficiently high temperatures.

Luminescence Dating: Applications in Earth Sciences and Archaeology

The best success from TL dates on chipped stone artifacts likely are from events when they were deposited into a hearth and accidentally fired. Surfaces of buildings and walls : The buried elements of standing walls of archaeological ruins have been dated using optically stimulated luminescence; the derived date provides the age of burial of the surface. In other words, the OSL date on a foundation wall of a building is the last time that foundation was exposed to light before being used as the initial layers in a building, and hence when the building was first built.

Others : Some success has been found dating objects such as bone tools, bricks, mortar, mounds, and agricultural terraces. Corrected feldspars ages are in good agreement with the quartz results for both samples.

This Luminescence dating is used to date the time since last practice of reporting .. that younger samples are better suited to optical dating than to TL dating. Optically Stimulated Luminescence (OSL) can routinely measure the age of flint using OSL and TL (thermoluminescence), respectively, can provide the best means of It is crucial that at the timescale PalaeoChron is working multiple dating. Preface. These guidelines are designed to establish good practice in the use of luminescence dating for providing chronological frameworks. They provide.

Huntley et M. At a shorter time scale e. Finally, historical phases of sediment aggradation were dated, with the accuracy of the age results being confirmed by historical archives.

The method was integrated into several research topics tab. In parallel it allowed methodological improvements e. However, it is worth noting that most of the data are used for local reconstructions, and that quantitative large-scale studies e.

This might be explained by the methodological limits of the OSL method, which in particular relate to the anomalous fading of feldspars, the partial bleaching, and the age uncertainty. This latter derives from the addition of uncertainties which concern both the dose rate e. As a consequence it is important especially for old sediments not to exclude it from the interpretation. Despite these limits the weak number of publications including OSL dating in France should however not be interpreted in terms of the accuracy of the method, as it may be successfully compared with other common dating methods: i the thermoluminescence methods are commonly used for archaeological or volcanic materials, especially because of the mineral composition of the studied material.

For other sediments OSL dating is typically used as it focuses on the light-sensitive part of the signal which is faster and more completely bleached while TL also measures the non-bleachable signal Duller, ; hence OSL dating makes it possible to date younger sediments, and to reduce the occurrence of partial bleaching; ii in opposition to radiocarbon, OSL dating is applied to sediment sequences that contain no organic material.

It can also be used for longer time-scales up to several hundreds of kawhile radiocarbon cannot be used for materials older than ka. From a geomorphological point of view optical luminescence also presents the advantage that it dates directly the deposited material; iii cosmogenic dating methods are used principally for age estimates of surfaces e.

Furthermore, it is more difficult to obtain several ages on a given vertical profile, while the OSL dating methods makes it possible to get a high-resolution chronological reconstruction; iv the Electron Spin Resonance method is applicable to material that is up to several hundreds of thousands years old, but is typically applied to palaeontological remains bones or teeth. Even if accurate ages have been obtained for aeolian or fluvial sediments Antoine et al.

It is however important to try and get as often as possible an independent age-control to improve the reliability of the results. It may derive from archaeological or historical data, from the recognition of palaeoenvironmental evidence pollens, periglacial features; Wintle,or from comparison with other absolute dating techniques e.

It is however important to note that the comparisons between optical dating of quartz and independent age controls often show good correlations e.

The above-mentioned methodological limits should not be considered as fixed in regard to the constant improvements which have characterised the OSL method for more than twenty years SAR protocol, development of the small aliquots and single grain analyses, improvements in the anomalous fading estimate and in the statistical treatment, applications to new kinds of sediments.

Hence the reason justifying the rarity of studies using OSL should very likely be attributed to the lack of laboratories in France in comparison with other countries 2 laboratories in France but ca.

This fact is all the more regrettable in that research worldwide shows that the optical dating method represents one of the most useful geochronological tools in geomorphological studies. However, it is important to keep in mind that not all sediments from all sections can be successfully dated: geomorphological field expertise before sampling remains essential in order to target the sediments showing a higher probability for complete bleaching, since only these sediments will allow an accurate age to be obtained.

Methodological improvements have enlarged the field of applications, but have also supported the development of quantitative geomorphology. In the same way it is an essential tool for research focusing on the existence of morphological thresholds, or dealing with the influence of forcing e.

For example L. Clemmensen et al. Based on these statements, the perspectives for applying the OSL method to geomorphological research in France are various. This can subsequently be used for sediment budget estimation during the Pleistocene climatic cycles, completing the results presented by M.

Frechen et al. The reconstruction of coastal dune formation may actually help us to understand their dynamics, which in turn can be used to assess their response to an increase of storms and their management in a context of sea-level rise; iii in fluvial environments OSL may be applied both to sediments which lack age control as it is the case for many terrace staircases and to sediments which have already been dated using other methods such as ESR e.

From an applied point of view, the acquisition of an extensive dataset is essential for a better understanding of fluvial response to environmental changes and for sediment budget reconstructions e. This is especially the case of glaciogenic deposits especially fluvio-glacial to glacio-lacustrine which are preserved in all the French mountains and often include sand-sized deposits potentially suitable for OSL dating; v the dating of slope-deposits lato sensu may be used to achieve a better understanding of the influence of human societies on slope dynamics, as well as for hazard management.

Evidence for this is shown by the worldwide increase in the number of laboratories and publications. A similar observation has been made in the general review of S.

Stokesbut associated with the persistence of methodological problems. Ten years later, most of these problems seem to have been overcome: even if the operating procedures may vary from one laboratory to another e.

The method should therefore contribute to the development of quantitative geomorphology Singhvi and Porat,as it makes it possible to recognise sedimentary discontinuities identification and dating of the thresholds separating erosive and aggradational periodsor to estimate aggradation rates.

Luminescence properties of minerals used in dating are then incremental doses are administered on top of the natural dose and then. The best sampling strategies are those that involve communication between a geomorphologist and luminescence dating expert prior to and during the field. derived sediments are usually considered the best candidates for luminescence dating because airborne time allows ample sun exposure.
