Recent Applications of Luminescence Dating in Archaeology

Recent Applications of Luminescence Dating in Archaeology

The field of Luminescence Dating has reached a level of maturity. Both research and applications from all fields of archaeological science, from archaeological materials to anthropology and geoarchaeology, now routinely employ luminescence dating. The advent of optically stimulated luminescence OSL techniques and the potential for exploring a spectrum of grain aliquots enhanced the applicability, accuracy and the precision of luminescence dating. The present contribution reviews the physical basis, mechanisms and methodological aspects of luminescence dating; discusses advances in instrumentations and facilities, improvements in analytical procedures, and statistical treatment of data along with some examples of applications across continents, covering all periods Middle Palaeolithic to Medieval and both Old and New World archaeology. They also include interdisciplinary applications that contribute to palaeo-landscape reconstruction. Convert currency.

Luminescence Dating

Luminescence dating is an absolute radiometric method of determining the age of a material since a key event in its history – typically burial in the case of sediments or firing in the case of ceramics or burnt stone. When a geological sediment is buried, the effects of the incoming solar radiation are removed. With this bleaching effect removed, the influence, albeit often weak, of naturally-occurring radioactive elements primarily potassium, uranium and thorium within the sediment together with incoming cosmic rays results in the accumulation of a signal within individual mineral grains most commonly quartz and feldspars.

It is this signal that is the key to luminescence dating techniques.

Burbidge, C. Technical Report. This study supports a new investigation into the construction, occupation and utilisation history of a Mediaeval ring fort near Newry, southwest Northern Ireland section 2. Optically stimulated luminescence OSL profiling and age determinations have been made for two sequences of sediments accumulated in the ring ditch surrounding the fort, and potential has been assessed for TL dating of a Souterrain-Ware sherd from a pit feature within the site complex section 3.

Luminescence dating quantifies the radiation exposure experienced by target minerals (usually quartzes or feldspars) from the sample as an “equivalent dose”,​.

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. Sauer at the University of Edinburgh, a PhD project has started to investigate the application of OSL and geomorphological techniques to establish the chronology of irrigation systems and settlement sites associated with the demographic growth at the frontiers of the Sasanian Empire.

The availability of chronologies for aeolian horizons obtained using OSL provides a valuable tool in the study of the evolution of coastal landscape and how past coastal communities responded to climate change.

Luminescence dating refers to a group of methods of determining how long ago mineral grains were last exposed to sunlight or sufficient heating. It is useful to geologists and archaeologists who want to know when such an event occurred. It uses various methods to stimulate and measure luminescence. All sediments and soils contain trace amounts of radioactive isotopes of elements such as potassium , uranium , thorium , and rubidium.

Luminescence dating provides a direct age estimate of the time of last exposure of quartz or feldspar minerals to light or heat and has been successfully applied.

Archaeological sites often contain teeth from animals or humans or the site is contained in quartz bearing sediment. When sediments cover an archaeological site they are exposed to light and the mineral grains are bleached.

1.4 Luminescence dating in archaeology

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.

Luminescence dating is a well-established dating technique applicable to materials exposed to either heat or light in the past, including ceramics, fired lithics, and sediments. One advantages of luminescence dating, especially for ceramics, is that it directly dates the manufacture or last use of the pottery, rather than inferring a date from association of pottery with 14C-dated organic materials. In the past two decades, the application of luminescence dating has gradually increased in archaeological studies in the U.

Several studies using luminescence dating for ceramics and sediments have been published recently. Recognizing that luminescence dating may now be “coming of age” in archaeology, we present in this session several recent applications of luminescence dating in archaeology. The goal of the session is to illustrate some of the potential of luminescence dating to answer research questions in archaeology.

This study provides an example of the potential for optically stimulated luminescence OSL dating to resolve chronological questions that cannot be adequately addressed using conventional radiocarbon dating alone. This site can be understood as a persistent place, with several occupations ranging from at least BP to recent times, when Artifact assemblages from the Arizona Strip and adjacent area are characterized by widely distributed ceramics tempered with olivine, a volcanic mineral.

Sources of olivine lie in the vicinity of Mt. Trumbull and Tuweep, near the northwestern part of the Grand Canyon. The olivine-tempered ceramics were distributed mostly westward from Mt. Trumbull, up to km to the lowland Virgin area in southern Nevada between A. Ultimately, the goal of this study is to understand why ceramic

OSL Dating in Archaeology

Desert Archaeology crew chief Caleb E. Ferbrache explains how electrons trapped in rock can be used to date archaeological deposits—and why, unlike the more familiar carbon dating, OSL allows dating in the absence of preserved organic material. Most people know that archaeologists regularly use carbon also called radiocarbon to date materials they find. While radiocarbon dating revolutionized archaeology and remains the most common dating method in the discipline, it is not the only method available.

Under the direction of Dr. Jim Feathers, this laboratory provides dating service using optically-stimulated luminescence (OSL) and thermoluminescence (TL). sediments in order to elucidate depositional sequences at archaeological sites.
