| 英文摘要 | We have conducted a detailed mineral magnetic study of loess unit 8 (L8) and paleosol unit 8 (S8) from three localities (Jingbian, Yichuan, and Dunajiapo) along a N-S transect in the Chinese loess plateau. As expected, the low-field magnetic susceptibility (chi) has higher values in S8 and lower values in L8. Similarly, superparamagnetic: particle concentrations increase in S8 with increasingly humid climates along the N-S transect, which suggests that pedogenic magnetic enhancement is related to climate. However, in S8 at Duanjiapo, chi is so low that there is no correlation between chi and the degree of pedogenesis in this loess-paleosol cycle. It therefore appears that chi is not consistently the most suitable indicator of paleoclimate in Chinese loess-paleosol sequences. Our results indicate that there are complexities in the mineral magnetic response to pedogenesis, which could invalidate interpretation of the chi record of Chinese loess-paleosol sequences in terms of paleoprecipitation. |
