    Tl dating range

    Stimulating samples using infrared light causes luminescence, the intensity of which varies depending on the amount of radiation absorbed.Exposure to sunlight resets the luminescent signature and so the time period since the sediment was buried can be calculated.Although a relatively new technique, particularly in subaqueous sediments, Strata Data have pioneered its industrial application in dating superficial seabed deposits for geohazard risk assessment.

    The age range for pottery and other ceramics covers the entire period in which these materials have been produced.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.The potential of red thermoluminescence (RTL) emission from quartz, as a dosimeter for baked sediments and volcanic deposits, has received some attention over the past decade.While there have been some important observations relating to signal stability, saturation characteristics and emission wavebands, there has not been a systematic analysis of RTL properties of older (i.e., 1 Ma), quartz-bearing known age volcanic deposits.
