The last 2. To be able to fully understand and interpret past climate variations the development of accurate and precise chronological techniques is crucial. Optically stimulated luminescence OSL dating is a strong geochronological tool that can be used to date across a wide time range, from the modern days to a few hundred thousand years ago.
It has been used to date sediments in nearly all parts of the world.

Optically stimulated luminescence dating at Rose Cottage Cave. A single-grain analysis demonstrates that the testing procedure for feldspar fails to reject single aliquots containing feldspar and the overestimate of age is attributed to this. Seven additional luminescence dates for the Middle Stone Age layers combined with the 14 C chronology establish the terminal Middle Stone Age deposits at 27 years ago, while stone tool assemblages that are transitional between the Middle Stone Age and the Late Stone Age are dated to between 27 years and 20 years ago.
Although there are inconsistencies in the Middle Stone Age dates, the results suggest that the Howiesons Poort at Rose Cottage Cave dates to between 70 years and 60 years ago. Much of the rich archaeological heritage in southern Africa is older than 50 years, which is the limit of the ubiquitous 14 C dating technique. In order to make appropriate inter-site comparisons of artefactual evidence, and further to compare the trajectory of human adaptation with external factors such as changing climates, it is necessary to establish a reliable chronological framework.
Optically stimulated luminescence OSL dating has become one of the foremost techniques in establishing this framework. OSL is based on the build-up and release of radiation energy in crystalline minerals, typically quartz.

At the Netherlands Centre for Luminescence dating we develop new and improved luminescence dating methods, and we apply luminescence dating in collaboration with NCL partners and external users. We develop new and improved luminescence dating methods, and we apply luminescence dating in collaboration with NCL partners and external users. The Netherlands Centre for Luminescence dating is a collaboration of six universities and research centres in The Netherlands.
Luminescence dating determines the last exposure to light or heat of natural minerals, mainly quartz and feldspar. Thereby the method can be used to determine the time of deposition and burial of sediments, or the time of baking of ceramic artefacts pottery, brick.

Kaja Fenn. You might have heard about radiocarbon dating, but do you know about OSL dating? OSL stands for O ptically S timulated L uminescence, and is another method of determining when processes and events occurred in the past. It has some distinct advantages over radiocarbon dating, which I will discuss.
This volume holds a datelist of radiocarbon determinations carried out between and in support of research funded by English Heritage throught the Aggregates Levy Sustainability Fund. It contains supporting information about the samples and the sites which produced them, a comprehensive bibliography, and two indexes for reference and analysis. An introduction provides information about the scientific dating undertaken, and methods used for the analyses reported.
Details of technical reports available for programmes of dendrochronology, luminescence dating, and amino-acid racemization funded under this scheme are also provided. The datelist has been collated from information provided by the submitters of samples and the dating laboratories, in order to provide easy access to raw scientific and contextual data which may be used in further research. Many of the sites and projects from which dates have been obtained are in the process of publication.

COARS have been selected to help develop guidelines on the use of different dating techniques for Pleistocene sites and deposits, and produce a document for publication and web dissemination in the Historic England English Heritage guidelines series. Dating methods currently available for the Pleistocene are applicably to different time frames within this period, vary considerably in precision and accuracy, and in addition are also subject to rapid development and improvement.
The guidelines will cover a range of techniques useful for dating deposits, sites and artefacts of Palaeolithic or Pleistocene age, to cover the period from c. The guidelines will provide practical advice on the application of different dating methods available for Pleistocene archaeological projects in England. Many archaeological projects will be undertaken as a requirement of the planning process.
Historic England, and its predecessor English Heritage, have produced technical For advice in relation to the use of Luminescence Dating please contact Alex.
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.
These slowly decay over time and the ionizing radiation they produce is absorbed by mineral grains in the sediments such as quartz and potassium feldspar. The radiation causes charge to remain within the grains in structurally unstable “electron traps”. The trapped charge accumulates over time at a rate determined by the amount of background radiation at the location where the sample was buried.

Dating terraces, the most prominent feature of the agricultural landscape in many parts of the world, is a problem for archaeologists. This study presents an interdisciplinary approach that combines archaeological survey and excavations with direct sediment dating of terrace fill using Optically Stimulated Luminescence OSL. The study focuses on Ramat Rahel, a multi-period site located in the southern outskirts of modern Jerusalem, Israel, where, on a defined terraced slope chosen for a small-scale landscape archaeology project, three main phases of terrace construction and use were identified.
The results enable a comprehensive reconstruction of the changing local landscape through time and demonstrate the validity of OSL, when combined with archaeological investigations, as a reliable method for terrace dating.

The area was reclaimed by installing extended runoff terrace systems and hydraulic structures.
The agricultural terrace systems have so far been dated based on surface pottery, and the chronology of the systems is under debate. In this study, optically stimulated luminescence OSL and radiocarbon dating techniques were successfully applied to date these terrace systems.
