| 英文摘要 | Magnetic susceptibility, and its frequency dependence, are reported for 288 individual samples spanning the 8.3 m - thick S3 palaeosol/L4 loess couplet at an important site in the Chinese Loess Plateau. The resulting profile demonstrates that there is a very close link between magnetic properties and soil development: soil and loess sub-divisions recognised visually in the field are clearly reflected in both the bulk susceptibility data and in its frequency dependence. As found at all Chinese sites, the distribution of susceptibilities is bi-modal, one peak representing loess (median = 0.74 x 10(-6)m(3)/kg), the other representing palaeosol (median = 2.99 x 10(-6)m(3)/kg). This is the basis of the climatic proxy information. The Baoji section is the site of one of the most detailed grain-size analyses available anywhere (Ding et al., 1994), and we find a strong correlation between the resulting profile and the susceptibility data reported here. Frequency-dependence of susceptibility exhibits slight differences between the loess and palaeosol populations which we interpret as reflecting reduced transport distances during glacial intervals when the Siberian High causes stronger winds and expands southwards. |
