| 英文摘要 | Comparisons of red ratings (RR) with Fe-d, Fe-d/Fe-t, clay content, and magnetic susceptibility (chi) of two loess-paleosol sequences at Luochuan and Lingtai on China's Loess Plateau were conducted to study the possible relationship between RR and pedogenic degrees of the two loess-palecsol sequences, and to discuss whether the RR could become new paleo-climatic indicators. Results showed that the RR of the two loess-paleosol sequences had positive, highly significant (P < 0.01) correlations with: 1) citrate-bicarbonate-dithionite (CBD) extracted iron (Fed), 2) ratios of CBD extracted iron to total iron (Fed/Fet), 3) clay (< 2 mum), and 4) magnetic susceptibility (chi). This suggested that the RR of these loess-paleosol sequences could indicate degrees of loess weathering and pedogenesis and were potential paleo-climatic proxies. The strong correlations of RR to Fe-d and chi also implied that during pedogenic processes, pedogenic hematite in loess and paleosols were closely related to the amount of total secondary iron oxides and pedogenic ferrimagnetic minerals (predominantly maghemite). |
