A collection of over 100 individually orientated hand-samples was obtained from a 335 m loess section near Lanzhou, Northern China. Previous studies defined the Brunhes-Matuyama (B-M) boundary and Jaramillo normal subchron within the section. The position of these magnetic `markers' led to the suggestion of a basal age for the section of ~ 1.3 Ma. This disagrees significantly with a date of 2.45 Ma for the onset of loess accumulation at Lochuan, 500 km to the east of Lanzhou. The present study considers the section in far greater detail and has derived a complex magnetostratigraphy, isolating seven normal events within the lower 130 m of the section. A simple interpretation of this magnetostratigraphy suggests a basal age for the section in the region of 2.4 Ma. However, the relative chronology of the loess/palaeosol sequence, although appearing to confirm this basal age, has revealed that this simple interpretation of the magnetostratigraphy may not be justified.
