Figures & Tables

Geomorphology of the study region and location of the sections. The yellow dots with red centers show the archaeological sites mentioned in this studies, e.g., Yutian site (Han et al., 2014), Erfang site (Hou et al., 2012), Xiao Qaidam site (Huang et al., 1987, Brantingham and Gao, 2006; Sun et al., 2010), Lenghu site in the northern QB (Owen et al., 2006, Brantingham and Gao, 2006), Nuomuhong site (Zeng, 2006), Jiangxigou site (e.g., Madsen et al., 2006; Brantingham and Gao, 2006; Sun et al., 2012), and some sites in this study (HSZ, HBC and XRH). The red dots with white centers display the towns and sections in this region, respectively.
HARs found in Hongshanzui (HSZ) sites and Hebeicun (HBC) sites in the eastern QB.
Sections, samples and ages in this study. The OSL ages in the HBC1 section are cited from Yu et al. (2015), and those in the XRH1 and XRH5 sections are cited from Yu and Lai (2014). Few OSL ages in XRH5 section are a little different from Yu and Lai, (2014) due to the recalibration of average water contents.
OSL growth curves (A), decay curves (B), and component fitting of a decay curve (C) of sample HSZ 3-2.
Influences to the OSL and 14C ages from different positions in a hearth from the heating event.
Field hearth experiment and samples.
OSL and TL signals of samples beneath the hearth.
