Gao, G., 1988. Formation and development of the structure of collapsing loess in China. Eng. Geol., 25: 235–245.It is well known that in China the regional variations in microstructure of loess are in phase with the overall tendency for collapsibility, gradually decreasing from the northwest to the southeast. These differences are consistent with variations in climatic conditions. This indicates that the structure of collapsing loess is closely related to the climatic condition and geological environment. Based on the microstructure analyses, it can be assumed that the formation and development of the structure of collapsing loess in China has undergone five stages: the loessization stage, the formation stage, the development stage, the degeneration stage and the clayization stage. The five stages of loess regularly exist in different regions of the Loess Plateau. This also shows that under the modern climatic condition the collapsing loess in the northwest of the Loess Plateau in China is still developing. However, the feature of collapsing loess is gradually disappearing in the southeast of the Loess Plateau.
