Magnetic polarity stratigraphy of loess in West Qinling (Mts.) demonstrates that loess began to deposit in West Qinling at ca. 800 kaBP. Its material may come from the nearby Tibetan Plateau to the west. This suggests that a sharp change in air circulation and surface environment on and around the Tibetan Plateau occurred at that time.
