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.
Luminescence Dating Laboratory
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.
One alternative is optically stimulated luminescence.

The OSL optically stimulated luminescence dating method exploits dosimetric properties of grains of minerals naturally occurring in sediments and man-made materials. In archaeology the OSL method is used to date pottery and other heated materials e. When compared with the radiocarbon method it makes possible dating objects containing no organic matter or originating in periods for which the radiocarbon method is less accurate due to the shape or lack of the calibration curve.

Chronology is a crucial scientific question for both archaeologic and paleoenvironmental studies on the Qinghai-Tibetan Plateau QTP. In the QB, very few early archaeological sites were found, because of the erosional environment, which is not suitable for the preservation of human activity remains HARs. As a result, artifacts were usually found on the ground surface, e.
Methodologically, both OSL dating and 14 C dating should be suitable for archaeological sites in aeolian sediments. Hou et al.

1.4 Luminescence dating in archaeology
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.

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. They are now largely used to date not only palaeontological or organic remains, but also minerals that characterise detrital clastic sedimentary material.

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. Given an estimate of the rate of received ionizing radiation the dose rate, or D , and knowing the total accumulated dose the palaeodose; designated D E it is possible to derive an age since burial.
The measurement of time is a critical parameter in archaeology and In this and other contexts OSL dating has provided meaningful age.

Luminescence Dating in Archaeology, Anthropology, and Geoarchaeology: An Overview
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.
Better still, unlike radiocarbon dating , the effect luminescence dating measures increases with time.
(), luminescence dating methods were introduced into the archaeological context by Aitken et al. () with the thermoluminescence (TL) dating of pottery.
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 ].
