Stratigraphic exposures in the middle streams of the Yellow River are mainly composed of carbonate rocks of the Ordovician system, clastic rocks of the Carboniferous and the Permian systems, sandy-mud rocks of the Tertiary, Jurassic, Cretaceous, and Paleogene systems, laterite of the Neogene System, eolian loess and modern aeolian sand of the Quaternary system. The Quaternary loess has a great thickness and is characterized by loose texture, easily incompact with water and collapsibility, which is the major source material of the coarse mud and sand in the middle reaches of the Yellow River, including the aeolian sand distributed in the north part of the middle reaches of the Yellow River.
