Abstract
Chinese loess-paleosol sequence has archived the most detailed terrestrial records of past climatic and environmental changes. In this study, we concentrate on Zhuli loess section in northern Shandong, by sedimentary and magnetic and optically stimulated luminescence (OSL) methods. Based on the OSL ages, the basal age of the Zhuli section is 60ka extrapolated by sedimentation rates. Grain-size curves indicate that environment-sensitive size fractions of Zhuli section are 39.81-44.67μm and 79.43-89.12μm respectively, by analyzing grain-size class vs. standard deviation values method. The low-frequency magnetic susceptibility has a good correlation with the high-frequency magnetic susceptibility, and the grain size has a good correlation with the magnetic susceptibility.
