Figures & Tables

Location of the studied core (white circle) and previously published data (grey circles) presented in Table 3

Typical dose response curves for sample EMB400 for quartz (OSL), together with a typical decay curve (insets) Response curves were best fitted to a single saturating exponential. The dotted line presents a simple example of equivalent dose determination for one aliquot where Lx/Tx = 1.95 and D = 9.66 Gy.

All luminescence results shown in graphs with relative probability density functions (Berger 2010)

Preheat plateau test for sample EMB400 Each point represents the mean value from five independent aliquots that were measured for each preheat temperature.

Grain size distribution and geochemical parameters in the studied core: black circles – radiocarbon dates; grey circles – OSL dates

Geochemical parameters; lithology legend in Fig. 5

OSL and radiocarbon depth-age model plot: black circles – radiocarbon dates; grey circles – OSL dates, red curve – model based on the weighed mean age for each depth, grey stippled lines – 95% confidence intervals, transparent blue – uncertainty of ages
