英文摘要	Numerical dating of loess is important for Quaternary studies. Recent progress in post-infrared infrared-stimulated luminescence (pIRIR) signals from potassium-rich feldspar has allowed successful dating of Chinese loess beyond the conventional dating limit based on quartz optically stimulated luminescence (OSL) signals. In this study we tested the multiple-aliquot regenerative-dose (MAR) pre-dose multiple-elevated-temperature post-IR IRSL (pMET-pIRIR) procedure on samples from the palaeosol S5 (similar to 480 ka) and S8 (similar to 780 ka) layers from the Luochuan and Jingbian sections, respectively. The results show that (1) compared to sensitivity-corrected signal (L-x/T-x), a higher saturation dose is observed for the sensitivity-uncorrected MET-pIRIR signals (L-x), suggesting that MAR is advantageous for dating old samples; (2) negligible fading component can be achieved using the pMET-pIRIR procedure; (3) for the sample from the top of palaeosol S5, D-e values (1360 + 226/-167 Gy) broadly consistent with expected D-e (1550 +/- 72 Gy) can be obtained using the sensitivity-uncorrected 300 degrees C MET-pIRIR signal. Our study suggests that a D-e value of about 1800 Gy may be the maximum dating limit of Chinese loess using the MAR pMET-pIRIR procedure. (C) 2015 Elsevier B.V. All rights reserved.
