SU Ying, LIU Jun-feng. Study on Micro-structures of Loess in the Xianyang Downtown Area[J]. Bulletin of Soiland Water Conservation, 2006, 25(5): 4-9.DOI:
Micro-structural characteristics of loess in the Xianyang downtown area were revealed using scanning electron microscope.Results show that loess microstructures are horizontally different with different landscape units
and vertically vary with different loess layers.The micro-structural difference between loess layers and paleosols in a given profile is most obvious.Loess layers mainly have supporting-macrospore and mosaic-microspore semi-cementation structures
whereas paleosols mainly have flocculent and coagulum cementation structures.Within a landscape unit
loess in the third and second terraces of the Weihe River is mainly characterized by supporting-macrospore and mosaic-microspore semi-cementation structures
and loess in the first terrace
by mosaic-microspore and flocculent cementation structures.Structure characteristics are mainly controlled by the environments of sedimentation
