Cryosuction is the concept of negative pressure in freezing soil resulting from transformation of liquid water to ice in the soil pores whereby water migrates through soil pores to the freezing zone (through capillary action).Fine-grained soils such as clays and silts enables greater negative pressures than more coarse-grained soils due to the smaller pore size. In periglacial environments, this mechanism is highly significant and it is the predominant process in ice lens formation in permafrost areas.Several models for ice-lens formation by cryosuction exist, among others the Hydrodynamic model and the Pre-melting model, many of them based on the Clausius–Clapeyron relation with various assumptions, yielding cryosuction potentials of 11 to 12 atm per degree Celsius below zero depending on

- La criosuzione è la suzione capillare risultante dalla pressione negativa che si forma in un suolo congelato nel quale l'acqua, migrando per capillarità attraverso le porosità del suolo, raggiunge la zona di congelamento dove si trasforma in ghiaccio. I suoli a grana fine, come le argille e il silt, consentono l'instaurarsi di pressioni negative superiori a quelle dei suoli a grana più grossolana a causa della minore dimensione dei loro pori. In ambiente periglaciale questo meccanismo è particolarmente importante ed è il processo predominante nella formazione di lenti di ghiaccio nelle aree a permafrost. (it)
