This sediment record and a large set of Optical Stimulated Luminescence dates, 14C dates and biostratigraphical data, allowed to establish detailed relationships between climate change, sea-level oscillation, glaciation history and the sedimentary development of the Rhine fluvial system during the last glacial cycle (Marine Isotope Stages 5e-2, Eemian-Weichselian).
Here, we report optically stimulated luminescence dating of key sedimentary beds in and around a single Chobe Island.
Zenobia Jacobs and Richard Roberts of the University of Wollongong in Australia are experts in the technique of optically stimulated luminescence dating.
Optically stimulated luminescence dated sand dunes and Pleistocene beach ridges in northwest Ohio are used to reconstruct landscape modification more than 5000 yr after deglaciation.
Radiocarbon and optically stimulated luminescence dating of terracette sediments ranged in age from between 1500 and 2000 14C yr BP and between 16 and 0.30 ka, respectively.
Correlation using age estimates is also discussed, in relation to optically stimulated luminescence dating of sand lenses within terrace gravels in this region during the PASHCC project.
Radiocarbon and optically stimulated luminescence dating are applied to add numerical data to the relative ages of the sediments and landforms.
Optically stimulated luminescence dating indicates that the sands enclosing the upper surface accumulated around 270 ky ago, while the sands between the two surfaces were accumulating about 290 ky ago.
Optically stimulated luminescence dating of K-feldspar, (involving the correction for anomalous fading of the luminescence signal), indicates that the younger terraces have a probable age range of: T5 — 31 to 40 ka; and T4 — 100 to ∼ 280 ka.
Optically stimulated luminescence dating of drift sand deposits above and below the micropodzols provides robust ages for periods of aeolian activity, and confines the timing and maximum duration of soil formation.
