A map of the Inner-Mongolian reaches of the upper Yellow River, the locations of drilling cores and modern sample sites. Photographs ot these modern sampling sections are shown above and below the map.

The results of preheat plateau tests (a, c) and dose recovery tests (b, d). Samples LFQ-07 and LFQ-04 are of modern fluvial sediments; sample HDZ03-06 is from a drilling core.

(a) OSL decay cuives for zero (0), natural (N), test (TD, 3.65 Gy), and regeneration doses (R1 and R3, 1 Gy and 5 Gy, respectively) for Sample LFQ-6. (b). The growth curve for each of the modern samples (shown by the black lines); the red line with open circles denotes the average of all the growth curves, which is taken as the standardised growth curve.

De values of different grain sizes for modern samples versus downstream distance

Frequency distributions, probability density functions and radial plots of individual De values and errors for different grain sizes of LFQ-6 and LFQ-14

Relation between calibrated 14C and OSL ages, and depth.

The correlation between the recalibration 14C (the results were presented on the same time scale as OSL dates) and the OSL ages, and depth, in drilling cores.

OSL dating results for 14 modern fluvial samples.
