英文摘要The loess sediments widely distributed in the Central Shandong Mountains are sensitive records of East Asian monsoon changes for situating in a key region connected to the Eurasian Plate and the Pacific Ocean. However, the detailed processes of palaeoclimatic changes are poorly understood for the lack of high-resolution chronology. In this study, the chronology of Heishan loess palaeosol sequence in the Central Shandong Mountains is investigated using quartz SAR OSL and K-feldspar post-IR infrared (IR) stimulated luminescence (post-IR IRSL) dating method. The quartz is sensitive, fast component dominated and saturate at similar to 150 Gy (similar to 50 ka). The measured K-feldspar pIRIR(290) D-e showed no dependency on the first IR stimulation temperature between 50 degrees C and 260 degrees C. The K-feldspar pIRIR(290) ages are consistent with the stratigraphy up to similar to 75 ka. In establishing the chronological sequence for the study section, quartz OSL ages 50 ka were selected. Derived sedimentation rates show two relatively rapid stages of similar to 32.0 +/- 5.5 cm/ka for the palaeosol (similar to 11-8 ka) and similar to 54.8 +/- 1.1 cm/ka for the loess (similar to 34-30 ka). An erosional hiatus of loess between similar to 30 ka and similar to 17 ka is identified. We conclude that the pIRIR(290) of loess sediments is applicable for samples during similar to 8-75 ka.
