The standardised growth curve (SGC) method has been applied to potassium-rich feldspar (K-feldspar) from samples at the Nihewan Basin, northern China. It was observed that the shapes of SGCs obtained from multiple-aliquot regenerative-dose (MAR) and single-aliquot regenerative-dose (SAR) procedures are different at high doses (>900 Gy) for the multiple-elevated-temperature post-IR IRSL (MET-pIRIR) signals observed at high temperatures (e.g., 290 °C) This difference can be attributed to the presence of residual signals in the MAR SGCs due to solar bleaching involved in the MAR procedure. Similar shapes of the SAR and MAR SGCs were obtained after correcting for the residual signals. Comparing the D_e estimates for both methods suggests that the SAR SGCs yield more reliable results. We tested the SAR SGCs for sediments from the Dadaopo section in the Nihewan Basin, including materials from the Brunhes/Matuyama (B/M) boundary (~780 ka). By interpolating the central re-normalised L_n/T_n ratios onto the corresponding SAR SGCs, the 290 °C MET-pIRIR signals yielded ages in stratigraphic order, and the sample from the B/M boundary yielded an age estimate broadly consistent with the expected age. Our results suggest that the MET-pIRIR SAR SGC method has the potential to date samples up to ~700–800 ka in this region.
