Quartz pebbles or sandstone with Optically Stimulated Luminescence (OSL) Richter D () Advantages and limitations of thermoluminescence dating of.

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. The most common methods applied to minerals are cosmogenic radionuclides, electron spin resonance ESR and luminescence techniques.

The latter were first applied to burned minerals from archaeological artefacts [thermoluminescence TL method]. Improvements of this technique led to the development, for more than twenty years, of the optical dating method [commonly referred to as Optically Stimuled Luminescence OSL ] which is now applied to sediments from various origins Wintle, The aim of this paper is to provide people involved in geomorphological research a global overview about the principles and procedures of optical dating, from the field sampling to the age interpretation.

Most of the publications actually focus on one part of either the method e. The general principles of the method are described first. The paper then explains how OSL dating is applied to obtain a depositional age, through the field and laboratory procedures employed. These procedures are described as clearly as possible in order to provide useful information for geomorphologists interested in the method, and illustrated by a case study that has involved luminescence dating of fluvial sands samples LUM and LUM from the lower alluvial terrace of the Moselle River M1 terrace as defined by S.

Dating tsunami deposits: Present knowledge and challenges

In luminescence dating, the signal accumulates within minerals over time as a function of low level, natural radiation exposure. The datable event is that point in time when the signal was reset to zero and started to grow again. The signal is essentially a dosimeter, converting to a chronometer by estimating the rate of dose absorption. Find out about our luminescence dating service. The time dependent signal is sourced from naturally ubiquitous silt or sand sized mineral grains; principally quartz or feldspar.

Luminescence Dating

Luminescence characteristics of quartz from Brazilian sediments and constraints for OSL dating. This study analyzes the optically stimulated luminescence OSL characteristics of quartz grains from fluvial, eolian and shallow marine sands of northeastern and southeastern Brazil, with especial focus on the applicability of the single-aliquot regenerative dose SAR dating protocol. All analyzed Brazilian sediments presented relatively high OSL sensitivity and good behavior regarding their luminescence characteristics relevant for radiation dose estimation.

While the shallow marine and eolian samples showed a narrow and reliable dose distribution, the fluvial sample had a wide dose distribution, suggesting incomplete bleaching and natural doses estimates dependent on age models. Luminescence is the light emitted by some materials, previously exposed to ionizing radiation, when stimulated by some type of activating energy Huntley

In these guidelines, section 1 provides a summary of the method and section 5 gives some indications of what samples are suitable and what age limits are.

Recent developments in our understanding of the limitations of optically stimulated luminescence as a dating tool are presented alongside summaries of results obtained on other luminescence signals measured in sedimentary quartz grains.

8. Luminescence Dating in Fluvial Settings: Overcoming the Challenge of Partial Bleaching

The impetus behind this study is to understand the sedimentological dynamics of very young fluvial systems in the Amazon River catchment and relate these to land use change and modern analogue studies of tidal rhythmites in the geologic record. Many of these features have an appearance of freshly deposited pristine sand, and these observations and information from anecdotal evidence and LandSat imagery suggest an apparent decadal stability.

Signals from medium-sized aliquots 5 mm diameter exhibit very high specific luminescence sensitivity, have excellent dose recovery and recycling, essentially independent of preheat, and show minimal heat transfer even at the highest preheats.

Limitations The limiting factor in the age range for luminescence dating is the ‘​saturation’ of the signal at large dose rates i. Accurate age determination therefore.
