Abstract

In contrast to the extensive investigation of the pedogenic magnetic component, the origin of long-term variations in the lithogenic susceptibility of Chinese eolian deposits has rarely been investigated. In this study, we conducted a linear correlation analysis of rock magnetic parameters of representative loess-red clay sections from the Chinese Loess Plateau. We found that lithogenic susceptibility of the deposits exhibited three dramatic increases, at similar to 2.75, 0.6, and 0.13 Ma. We argue that intensive erosion or physical weathering in the NE Tibetan Plateau, induced by late Pliocene global cooling and tectonic uplift, may be responsible for the increases in lithogenic susceptibility over the past 3.6 Ma. Furthermore, the magnetic properties of water-reworked sediments deviate from the linear regression line for the eolian deposits of the Chinese Loess Plateau, suggesting that regression analysis may provide a rapid method for distinguishing between sediments of eolian and fluvial origin in the region.
