Magnetic remanence and bulk susceptibility measurements are reported from 93 samples spanning the uppermost 27 m of the Red Clay underlying the loess sequence at Baoji, Shaanxi province, China. If a new, previously undetected, short (about 20 ka) excursion or reversed interval near 3.3 Ma be accepted, then a reasonable fit to the standard time scale emerges. A linear accumulation rate of 1.5 cm/ka is implied and the correlation coefficient is 0.992. No significant hiatus occurs between the Red Clay and the overlying loess, so the 27 m investigated reach back to about 4.3 Ma. Fourier analysis of the bulk susceptibility data yields a strong peak near 400 ka in agreement with astronomical calculations of the orbital parameters responsible for climatic forcing. ¿ American Geophysical Union 1991
