10Be and magnetic susceptibility have been measured in the top 12 m of a loess profile from Luochuan, Central China. Comparison of the 10Be concentration record with the SPECMAP Δ18O profile of the last 130 ka (Imbrie et al., 1984> results in a new time scale which is in good agreement with that of Kukla et al. [1990>. The calculated loess accumulation reates can be compared with existing records of dusts falls in Pacific deep sea sediments and Antarctic ice cores. A simple model for the 10Be dust flux demonstrates that a significant part of the magnetic susceptibility signal in palaesol horizons is due to in situ pedogenic production. During times of high loess accumulation (cold paleoclimate) this contribution is negligible. ¿American Geophysical Union 1993
