  • The Yellow River is of special hydrology, hydodynamics, sedimentary environment and deposits, resulting in forming a lot of unusual sedimentary phenomina: one of them is ice-induced slump or subsidence structure. Ice-induced slump and subsidence structure are considerably common in the lower course of the Yellow River. They mainly develop in the point bar and/or channel bar, sometimes also in levee. Their development influences and remakes the sedimentary views of the point bar and channel bar. Ice-induced slump structure is an unusual structure that is formed in such a state that the sediment is transformed from the being frozen to being melt, and its motion is featured by sliding, mainly with horizontal motion. Those ice-induced structures developing in the point bar and/or channel bar are like scales or wrinkles. Those ones like scales composed by several to more than ten,are dozens of centimeters in diameters with the thickness of mostly ten of centimeters,and their bottom boundaries are frozen ones; and those ones like wrinkles are very small in size and each wrinkle is below one centimeter in width, ten to thirty centimeters in length and two or three centimeters in thickness. Sometimes, a specical ice-induced slump may be seen in levee and it makes the edge of levee look like steps or gullies. Also, the ice-induced subsidence structure is a kind of special structures formed by ice layer's melting and its motion feature is subsiding, mainly moving vertically. Ice-melt-induced subsidence structures have the multangylar shapes and look hole-like. Their diameters are mostly several tens of centimeters to one or two meters and the largest may amount to more than ten meters and the depth is more than ten centemeters. They often develop in groups.

Abstract: The Yellow River is of special hydrology, hydodynamics, sedimentary environment and deposits, resulting in forming a lot of unusual sedimentary phenomina: one of them is ice-induced slump or subsidence structure. Ice-induced slump and subsidence structure are considerably common in the lower course of the Yellow River. They mainly develop in the point bar and/or channel bar, sometimes also in levee. Their development influences and remakes the sedimentary views of the point bar and channel bar. Ice-induced slump structure is an unusual structure that is formed in such a state that the sediment is transformed from the being frozen to being melt, and its motion is featured by sliding, mainly with horizontal motion. Those ice-induced structures developing in the point bar and/or channel bar are like scales or wrinkles. Those ones like scales composed by several to more than ten,are dozens of centimeters in diameters with the thickness of mostly ten of centimeters,and their bottom boundaries are frozen ones; and those ones like wrinkles are very small in size and each wrinkle is below one centimeter in width, ten to thirty centimeters in length and two or three centimeters in thickness. Sometimes, a specical ice-induced slump may be seen in levee and it makes the edge of levee look like steps or gullies. Also, the ice-induced subsidence structure is a kind of special structures formed by ice layer's melting and its motion feature is subsiding, mainly moving vertically. Ice-melt-induced subsidence structures have the multangylar shapes and look hole-like. Their diameters are mostly several tens of centimeters to one or two meters and the largest may amount to more than ten meters and the depth is more than ten centemeters. They often develop in groups.
