Luminescence dating of glacial and associated sediments: review, recommendations and future directions
Dating glacial and associated sediments is essential to provide a temporal framework for accurate reconstructions of past climatic conditions and for helping to determine the nature and magnitude of glaciation for landscape evolution studies. There are few widely applicable, accurate and precise methods available to date Quaternary landforms and sediments, despite the numerous numerical dating ...
متن کاملPrecision and Accuracy in the Optically Stimulated Luminescence Dating of Sedimentary Quartz: a Status Review
Optically stimulated luminescence (OSL) dating of light-exposed sediments is used increasingly as a mean of establishing a sediment deposition chronology in a wide variety of late Quaternary studies. There has been considerable technological development in the last few years – in instrumentation, in the preferred mineral, and in various measurement protocols. New approaches to the latter, espec...
متن کاملUse of luminescence dating in archaeology
With improvements in methodology and instrumentation, luminescence dating is becoming a much more useful chronometric tool in archaeology. Procedures for dating ceramics are relatively routine and their accuracy has been demonstrated in a number of studies. Research is aimed at applying ceramic dating in situations where other methods lack the direct dating ability of luminescence to resolve ch...
متن کاملOptically stimulated luminescence in synthetic quartz
Optically stiniulated luminescence (OSL). has been studied in synthetic quartz crystals. which had previously been exposed to Jtor X-irradiations. The main emission hands appeared at 380 and -~440 nm. The excitation spectra of these emission bands were now measured and showed both a maximum at 330nm. This maximum coincides with an excitation maximum of the phototransferred thermoluminescence (P...
متن کاملIsochron dating of sediments using luminescence of K-feldspar grains
[1] A new method for dating well-bleached sediments is presented, with results for thirteen samples from China. The method uses an isochron constructed from the measurement of natural radiation doses received by potassium-feldspar grains in a range of grain sizes using the infrared stimulated luminescence (IRSL) signal. The age of deposition of the sediment is calculated from this isochron and ...
