In this study, a sand-loess-soil sequence from the northern margin of the CLP was studied by applying K-feldspar the single aliquot regenerative (SAR) protocol to quartz grains, and the multi-elevated-temperature post-IR IRSL SAR (MET-pIRIR) protocol to K-feldspar grains. For equivalent dose (D ) determination, 63–90 μm quartz and K- MET-pIRIR feldspar grains were used. Our results indicate
