The primary loess on the Loess Plateau is an aeolian deposit in the dry and cold climate of Quaternary Glacial Period, and the secondary loess is transformed from the primary loess by flood and alluvial. During the Quaternary loess accumulation period, with the climate rotation of glacial and interglacial periods, the loess strata showed the alternation of loess and paleosol. According to the ancient soil in loess, loess stratum can be divided into Wucheng loess, Lishi loess, Malan loess and Holocene loess from bottom to top.
Loess is an aeolian deposit accumulated in arid and semi-arid environment under the action of wind blowing and transportation. After long-distance transportation and sorting, its material composition is highly uniform. Under the action of the northwest wind, a large amount of dust is transported to the Loess Plateau, deposited due to the weakening of the wind, and finally forms a thick loess accumulation year after year.
