| 英文摘要 | In the eastern Loess Plateau region of northern China, the Quaternary loess-soil sequences of the last 2.6 Ma are underlain by the Hipparion Red-Earth Formation. Magneto-stratigraphic studies suggest that it is a near continuous terrestrial record for the period from similar to7 to similar to2.6 Ma BP, and therefore, has great potential for the study of Asian paleoclimates. The origin of this formation is controversial and needs further study. In this work, the Xifeng Red-Earth section, a type section for the eastern Loess Plateau region, was studied using optical microscopic analysis, grain-size measurements, and both major- and trace-element geochemical properties to address questions of its origin and environmental implications. The results show that this formation consists of three parts. The Lower part (>6.2 Ma BP) is a water-reworked deposit related to alluvial and slope processes; the Middle part (from similar to6.2 to similar to3.6 Ma BP) was derived from in situ eolian dust deposition, but was significantly affected by groundwater oscillations; and the Upper part (from similar to3.6 to similar to2.6 Ma BP) is an eolian formation, similar to the Quaternary loess-soil sequence. The grain-size of the Upper part is significantly coarser than for the middle part, but finer than for the overlying loess. |
