Lithology and grain-size characteristics of FN1 core at Funing bay, Southeast China. And FN1 and FN2 core are located in intertidal zone and supratidal zone, respectively. (a) The distribution of median diameter with depth. The solid circles on FN1 lithology column represent the sampling location of OSL samples. (b) The distributions of different cumulative percentage composition with depth. (c) The sorting coefficient of sediment.

Luminescence characteristics. (a) and (b). Solid squares display equivalent dose as a function of preheat temperature for the medium grained quartz for the sample PFS005 and PFS012, respectively. Open squares and circles refer to the recycling ratios and recuperation values. (c). Dose recovery test data for sample PFS005 and PFS012.

Luminescence characteristics. Typical natural OSL decay curves (a–c) using the SAR procedure for mid-grained quartz of sample PFS001, PFS002 and PFS005. The OSL dose response curves (d–f) are plotted from all aliquots of each sample. Radial plots showing how broad the distribution of the De values of sample PFS001 (g), PFS002 (h), and PFS005 (i). The resultant De value of the central age model (Table 2) is shaded.
