Abstract

To provide more insight in the formation of S5 and its environmental significance, the pedogenesis and clay mineral transformation in the the fifth paleosol complex (S5) of the Wugong section (Shaanxi Province) on the southernmost Chinese Loess Plateau (CLP) are analyzed. S5, here, is essentially composed of 3 well-developed reddish pedons which signify three glacial–interglacial climatic fluctuations during its formation. Moreover, completely decalcification and clay transformation and translocation occur in the S5. However, chemical alteration of phyllosilicate minerals mainly is weak. Mineral weathering is restrained by calcic horizon, argillic horizon, flat terrain. Therefore, pedogenesis in a loess–paleosol sequence and its pedogenic environment can best be deduced from combined data on pedogenic properties, and geochemical and mineralogical characteristics
