The thickest loess occurs in central China on the Loess Plateau, where it reaches a thickness of about 330 m near Lanzhou. |
It has a relatively large component of loess and contains ovoid inclusions of loessic silt which were deposited by solifluction. |
The regionally immense deposits of rich loess soils, for example in the Midwest, are also of aeolian origin. |
The original substrate of the soils on the terrace surfaces in North Reutlingen consist of loess deposits in varying thicknesses. |
Many researchers have concluded this sediment is actually loess, or wind-blown silt, which is mixed with some clay and sand. |
The series consists of very deep, well drained, fine silty alfisol formed in loess. |
